Installing wxWidgets for Windows
-----------------------------------------------------------

This is wxWidgets for Microsoft Windows 9x/ME, Windows NT,
Windows 2000, Windows XP and Windows CE.

These installation notes can be found in docs/msw/install.txt
in your wxWidgets distribution.

IMPORTANT NOTE: If you experience problems installing, please
re-read this instructions and other related files (changes.txt,
readme.txt, FAQ) carefully before mailing wx-users. Preferably,
try to fix the problem first and then upload a patch to
SourceForge:

  http://sourceforge.net/patch/?group_id=9863

Please report bugs using the SourceForge bug tracker:

  http://sourceforge.net/bugs/?group_id=9863

Unarchiving
============================================================

A setup program is provided (wxMSW-x.x.x-setup.exe) to automatically copy
files to a directory on your hard disk. Do not install into a
path that contains spaces.

The setup program contains the following:

- All common, generic and MSW-specific wxWidgets source;
- samples and demos;
- documentation in MS HTML Help format;
- makefiles for most Windows compilers, plus CodeWarrior,
  BC++ and VC++ IDE files;
- JPEG library source;
- TIFF library source;
- Object Graphics Library, Tex2RTF, wxSTC, etc.

Alternatively, you may unarchive the .zip form by hand:
wxMSW-x.y.z.zip where x.y.z is the version number.

Unarchive the required files plus any optional documentation
files into a suitable directory such as c:\wx.

General installation notes
==========================

If installing from the SVN server, copy include/wx/msw/setup0.h to
include/wx/msw/setup.h and edit the resulting file to choose
the features you would like to compile wxWidgets with[out].

Compilation
===========

The following sections explain how to compile wxWidgets with each supported
compiler. Search for one of Microsoft/Borland/Watcom/Symantec/Metrowerks/
Cygwin/Mingw32 to quickly locate the instructions for your compiler.

All makefiles and project are located in build\msw directory.

Where compiled files are stored
-------------------------------

After successful compilation you'll find the libraries in a subdirectory
of lib directory named after the compiler and DLL/static settings.
A couple of examples:

  lib\vc_lib                    VC++ compiled static libraries
  lib\vc_dll                    VC++ DLLs
  lib\bcc_lib                   Static libraries for Borland C++
  lib\wat_dll                   Watcom C++ DLLs

Names of compiled wxWidgets libraries follow this scheme: libraries that don't
depend on GUI components begin with "wxbase" followed by version number and
letters indicating if the library is compiled as Unicode ('u') and/or debug
build ('d'). Last component of them name is name of wxWidgets component
(unless you built the library as single monolithic library; look for
"Configuring the build" below). This is a typical set of release ANSI build
libraries (release versions on left, debug on right side):

  wxbase29.lib              wxbase29d.lib
  wxbase29_net.lib          wxbase29d_net.lib
  wxbase29_xml.lib          wxbase29d_xml.lib
  wxmsw29_core.lib          wxmsw29d_core.lib
  wxmsw29_html.lib          wxmsw29d_html.lib
  wxmsw29_adv.lib           wxmsw29d_adv.lib

Their Unicode debug counterparts in wxUniversal build would be

  wxbase29ud.lib
  wxbase29ud_net.lib
  wxbase29ud_xml.lib        (notice these libs are same for wxUniv and wxMSW)
  wxmswuniv29ud_core.lib
  wxmswuniv29ud_html.lib
  wxmswuniv29ud_adv.lib

These directories also contain subdirectory with wx/setup.h header. This
subdirectory is named after port, Unicode, wxUniv and debug settings and 
you must add it to include paths when compiling your application. Some
examples:

  lib\vc_lib\msw\wx\setup.h          VC++ static, wxMSW
  lib\vc_lib\mswud\wx\setup.h        VC++ static, wxMSW, Unicode, debug
  lib\vc_lib\mswunivd\wx\setup.h     VC++ static, wxUniversal, debug

Below are compiler specific notes followed by customizing instructions that
apply to all compilers (search for "Configuring the build").

Microsoft Visual C++ compilation
----------------------------------------------------------------

You may wish to visit http://wiki.wxwindows.org/wiki.pl?MSVC for a more
informal and more detailed description of the process summarized below.

Please note that the VC++ 6.0 project files will work for VC++ .NET also.

VC++ 5.0 can also be used, providing Service Pack 3 is applied. Without it
you will have trouble with internal compiler errors. It is available for
download at: ftp://ftp.microsoft.com/developr/visualstudio/sp3/full.

Using project files (VC++ 6 and later):

1. Unarchive wxWidgets-x.y.z-vc.zip, the VC++ 6 project
   makefiles (already included in wxMSW-x.y.z.zip and the setup version).
2. Open build\msw\wx.dsw, which has configurations for static
   compilation or DLL compilation, and each of these available in
   Unicode/ANSI, Debug/Release and wxUniversal or native variations.
   Normally you'll use a static linking ANSI configuration.
   Choose the Win32 Debug or Win32 Release configuration (or any other that
   suits your needs) and use Batch Build to compile _all_ projects. If you
   know you won't need some of the libraries (i.e. html part), you don't have
   to compile it.  It will also produce similar variations on jpeg.lib,
   png.lib, tiff.lib, zlib.lib, and regex.lib.

   If you want to build DLL configurations in wx.dsw project you unfortunately
   need to build them in the proper order (jpeg, png, tiff, zlib, regex, expat,
   base, net, odbc, core, gl, html, media, qa, adv, dbgrid, xrc, aui, richtext)
   manually because VC6 doesn't always respect the correct build order.

   Alternatively, use the special wx_dll.dsw project which adds the
   dependencies to force the correct order (but, because of this, doesn't work
   for the static libraries) or simply redo the build several times until all
   DLLs are linked correctly. Pleae notice that it's normal that dbgrid project
   doesn't build if wxUSE_ODBC is set to 0 (default).
3. Open a sample project file, choose a configuration such as
   Win32 Debug using Build | Set Active Configuration..., and compile.
   The project files don't use precompiled headers, to save disk
   space, but you can switch PCH compiling on for greater speed.
   NOTE: you may also use samples/samples.dsw to access all
   sample projects without opening each workspace individually.
   You can use the Batch Build facility to make several samples
   at a time.

Using makefiles:

1. Change directory to build\msw. Type:

  'nmake -f makefile.vc'

   to make the wxWidgets core library as release DLL.
   See "Configuring the build" for instruction how to build debug or static
   libraries.

2. Change directory to samples and type 'nmake -f makefile.vc'
   to make all the samples. You can also make them individually.

Makefile notes:

  Use the 'clean' target to clean all objects, libraries and
  executables.

Note (1): if you wish to use templates, please edit
include\wx\msw\setup.h and set wxUSE_DEBUG_NEW_ALWAYS to 0.
Without this, the redefinition of 'new' will cause problems in
the headers. Alternatively, #undef new before including template headers.
You will also need to set wxUSE_IOSTREAMH to 0 if you will be
using templates, to avoid the non-template stream files being included
within wxWidgets.

Note (2): libraries and applications generated with makefiles and
project files are now (hopefully) compatible where static libraries
are concerned, but please exercise caution nevertheless and if
possible, use one method or the other.

Note (3): some crash problems can be due to inconsistent compiler
options. If strange/weird/impossible things start to happen please
check (dumping IDE project file as makefile and doing text comparison
if necessary) that the project settings, especially the list of defined
symbols, struct packing, etc. are exactly the same for all items in
the project. After this, delete everything (including PCH) and recompile.

Note (4): to create your own IDE files, copy .dsp and .dsw
files from an existing wxWidgets sample and adapt them, or
visit http://wiki.wxwindows.org/wiki.pl?MSVC.

Microsoft Visual C++ compilation for 64-bit Windows
----------------------------------------------------------------

Visual Studio 2005 includes 64-bit compilers, though they are not installed by
default; you need to select them during the installation. Both native 64-bit
compilers and 32-bit hosted cross compilers are included, so you do not need a
64-bit machine to use them (though you do to run the created executables).
Visual C++ Express Edition does not include 64-bit compilers.

64-bit compilers are also available in various SDKs, for example
the .NET Framework SDK:
    http://msdn.microsoft.com/netframework/programming/64bit/devtools/

Using project files:

1. Open the VC++ 6 workspace file: build\msw\wx.dsw. Visual Studio will then
   convert the projects to the current Visual C++ project format.

2. To add 64-bit targets, go to the 'Build' menu and choose 'Configuration
   Manager...'.  In the 'Active solution platform' drop down choose '<new>',
   then you can choose either 'Itanium' or 'x64'.

   For more detailed instructions see:
    http://msdn2.microsoft.com/en-us/library/9yb4317s(en-us,vs.80).aspx

   Note: 64-bit targets created this way will use the build directory of the
         corresponding 32-bit target for some files. Therefore after building
         for one CPU it is necessary to clean the build before building the
         equivalent target for another CPU. We've reported the problem to MS
         but they say it is not possible to fix it.

3. To build, go to the 'Build' menu and choose 'Batch Build...'. Tick all the
   all the 'x64|Debug' or all the 'Itanium|Debug' projects, and click 'Build'.

   This will build a debug version of the static libs. The section above on
   Visual C++ in general has more information about adjusting the settings to
   build other configurations.

4. To compile one of the samples open one of the sample projects, such as
   samples\minimal\minimal.dsw. Visual Studio will convert the project as in
   step 1, then add a 64-bit target as in step 2, and build.

Using makefiles:

1. Open a 64-bit build command prompt, for either x64 or Itanium. Change
   directory to build\msw. Then for x64 type:

    nmake -f makefile.vc TARGET_CPU=AMD64

   or for Itanium:

    nmake -f makefile.vc TARGET_CPU=IA64

   This will build a debug version of wxWidgets DLLs. See "Configuring the
   build" for instruction how to build other configurations such as a release
   build or static libraries.

2. Change to the directory of one of the samples such as samples\minimal. Type
   the same command used to build the main library, for example for x64:

    nmake -f makefile.vc TARGET_CPU=AMD64

Notes:

The versions of the VC++ 8 compiler included with some SDKs requires an
additional library to be linked or the following error is received.

    LNK2001 unresolved external symbol __security_check_cookie

If you receive this error add bufferoverflowu.lib to link, e.g.:

    nmake -f makefile.vc TARGET_CPU=AMD64 LDFLAGS=bufferoverflowu.lib

See http://support.microsoft.com/?id=894573 for more information.

Borland C++ compilation
----------------------------------------------------------------

The minimum version required is 5.5 (last version supported by BC++ 5.0 was
2.4.2), which can be downloaded for free from:
http://www.borland.com/products/downloads/download_cbuilder.html

We have found that the free Turbo Explorer and commercial BDS work fine; the 
debugger is very good. To avoid linker errors you will need to add 
-DSHARED=1 to the makefile line for the library

The version 5.6 included in Borland C++ Builder 2006 works as well after the
following small change: please remove the test for __WINDOWS__ from line 88
of the file BCCDIR\include\stl\_threads.h.

Compiling using the makefiles:

1. Change directory to build\msw. Type 'make -f makefile.bcc' to
   make the wxWidgets core library. Ignore the compiler warnings.
   This produces a couple of libraries in the lib\bcc_lib directory.

2. Change directory to a sample or demo such as samples\minimal, and type
  'make -f makefile.bcc'. This produces a windows exe file - by default 
   in the bcc_mswd subdirectory.

Note (1): the wxWidgets makefiles assume dword structure alignment. Please
make sure that your own project or makefile settings use the
same alignment, or you could experience mysterious crashes. To
change the alignment, change CPPFLAGS in build\msw\config.bcc.

Note (2): if you get undefined _SQL... symbols at link time,
either install odbc32.lib from the BC++ CD-ROM into your BC++ lib
directory, or set wxUSE_ODBC to 0 in include\wx\msw\setup.h and
recompile wxWidgets. The same applies if compiling using the IDE.

Note (3): If you wish debug messages to be sent to the console in
debug mode, edit makefile.bcc and change /aa to /Tpe in link commands.

Using the Debugger and IDE in BDS or Turbo Explorer
---------------------------------------------------


Doubleclick / open samples\minimal\borland.bdsproj. The current version 
is to be used with a dynamic build of wxWidgets-made by running
make -f Makefile.bcc -DBUILD=debug -DSHARED=1
in wxWidgets\build\msw. You also need the wxWidgets\lib\bcc_dll
directory in your PATH. The debugger tracks your source and also
traces into the wxWidgets sources.

To use this to debug other samples, copy the borland_ide.cpp
and borland.bdsproj files, then replace all occurences of
"minimal" with the name of the new project files

Compilation succeeds with CBuilderX personal edition and CBuilder6, but 
you may have to copy make.exe from the 5.5 download to the new bin directory.

Compiling using the IDE files for Borland C++ 5.0 and using CBuilder IDE 
(v1-v6): not supported 



** REMEMBER **

In all of your wxWidgets applications, your source code should include
the following preprocessor directive:

#ifdef __BORLANDC__
#pragma hdrstop
#endif

(check the samples -- e.g., \wx2\samples\minimal\minimal.cpp -- for
more details)

Borland 16 Bit compilation for Windows 3.1
----------------------------------------------------------------

The last version of wxWidgets to support 16-bit compilation with Borland was
2.2.7 - Please download and read the instructions in that release

Watcom C++ 10.6/11 and OpenWatcom compilation
----------------------------------------------------------------

1. Change directory to build\msw. Type 'wmake -f makefile.wat' to
   make the wxWidgets core library.

2. Change directory to samples\minimal and type 'wmake -f makefile.wat'
   to make this sample. Repeat for other samples of interest.

Note (1): if your installation of Watcom doesn't have odbc32.lib file and
          you need it (i.e. you have wxUSE_ODBC=1), you can use the file
          from lib\watcom directory. See the notes in that directory.

Note (2): if variant.cpp is compiled with date/time class options, the linker
          gives up. So the date/time option is switched off for Watcom C++.
          Also, wxAutomationObject is not compiled with Watcom C++ 10.

Note (3): RawBitmaps won't work at present because they use unsupported template
          classes

Note (4): if Watcom can't read the precompiled header when building a sample,
          try deleting .pch files in build\msw\wat_* and compiling
          the sample again.

Note (5): wxUSE_STD_STRING is disabled in wx/string.h for Watcom as this
          compiler doesn't come with standard C++ library headers by default.
          If you install STLPort or another STL implementation, you'll need to
          edit wx/string.h and remove the check for Digital Mars in it (search
          for __WATCOM__).


Metrowerks CodeWarrior compilation
----------------------------------------------------------------

** NOTE: We don't use Metrowerks compiler any more and so depend on
**       your contributions to keep it up to date. It is possible that
**       the project files mentioned below are out of date due to recently
**       added files, please add them manually if you get linking errors.
**       The authoritative list of files is in build/bakefiles/files.bkl

1. CodeWarrior Pro 7 project files in XML format are already
   included in wxMSW-2.8.x.zip and the setup version.

2. Review the file include\wx\msw\setup.h (or include\wx\msw\setup0.h if
   you are working from the SVN version) to make sure the settings reflect
   what you want.  If you aren't sure, leave it alone and go with the
   default settings.  A few notes:
       - Don't use wxUSE_DEBUG_NEW_ALWAYS: it doesn't mix well with MSL
       - wxUSE_GLOBAL_MEMORY_OPERATORS works, but memory leak reports
         will be rather confusing due to interactions with the MSL ANSI
         and runtime libs.

3. The project file to build the Win32 wxWidgets libraries relies on the
   Batch File Runner plug-in.  This plug-in is not installed as part of
   a normal CW7 installation.  However, you can find this plug-in on the
   CodeWarrior Reference CD, in the Thrill Seekers folder; it's call the
   "Batch File Post Linker".

4. If you choose not to install the Batch File Runner plug-in, then you
   need to do the following by hand:
      (1) Create the directories lib\cw7msw\include\wx and copy the file
          include\wx\msw\setup.h (or include\wx\msw\setup0.h if you are
          working from the SVN version) to lib\cw7msw\include\wx\setup.h
      (2) Create the directories lib\cw7mswd\include\wx and copy the file
          include\wx\msw\setup.h (or include\wx\msw\setup0.h if you are
          working from the SVN version) to lib\cw7mswd\include\wx\setup.h

5. Import src\wxWidgetsW7.xml to create the project file wxWidgetsW7.mcp.
   Store this project file in directory src.  You may get warnings about
   not being able to find certain project paths; ignore these warnings, the
   appropriate paths will be created during the build by the Batch File Runner.

6. Choose the wxlib Win32 debug or wxlib Win32 Release target and build.  You
   will get some warnings about hidden virtual functions, illegal conversions
   from const pointers to pointers, etc., all of which you can safely ignore.
   ***Note:  if you get errors that the compiler can't find "wx/setup.h", just
   stop the build and build again.  These errors occur because sometimes the
   compiler starts doing its thing before the copying of setup.h has completed.

7. The following libraries will be produced depending on chosen
   target:
       - wx_x86.lib             ANSI Release (static)
       - wx_x86_d.lib           ANSI Debug (static)

8. Sorry, I haven't had time yet to create and test unicode or DLL versions.
   Volunteers for this are welcome (as neither DLLs nor unicode builds are
   big priorities for me ;).

9. CodeWarrior Pro7 project files (in XML format) are also provided for some
   of the samples.  In particular, there are project files for the minimal,
   controls, dialogs, dnd, nd docview samples.  You can use these project
   files as templates for the other samples and for your own projects.
       - For example, to make a project file for the "grid" sample,
         just copy the project file for the "minimal" sample, minimalW7.mcp
         (made by importing minimalW7.xml into CodeWarrior), into the
         sample/grid directory, calling it gridW7.mcp.  Open
         newgridW7.mcp and revise the project by deleting the files
         minimal.rc and minimal.cpp and adding the files griddemo.rc and
         griddemo.cpp.  Build and run....


Cygwin/MinGW compilation
----------------------------------------------------------------

wxWidgets supports Cygwin (formerly GnuWin32) betas and
releases, and MinGW. Cygwin can be downloaded from:

    http://sources.redhat.com/cygwin/

and MinGW from:

    http://www.mingw.org/

Both Cygwin and MinGW can be used with configure (assuming you have MSYS
installed in case of MinGW). You will need new enough MinGW version, preferably
MinGW 2.0 (ships with gcc3) or at least 1.0 (gcc-2.95.3). GCC versions older
than 2.95.3 don't work; you can use wxWidgets 2.4 with them.

NOTE: some notes specific to old Cygwin (< 1.1.x) are at the end of this
      section (see OLD VERSIONS)

There are two methods of compiling wxWidgets, by using the
makefiles provided or by using 'configure'.

Retrieve and install the latest version of Cygwin, or MinGW, as per
the instructions with either of these packages.

If using MinGW, you can download the add-on MSYS package to
provide Unix-like tools that you'll need to build wxWidgets using configure.

Using makefiles directly
----------------------------------------------------------------

NOTE: The makefile.gcc makefiles are for compilation under MinGW using
      Windows command interpreter (command.com/cmd.exe), they won't work in
      other environments (such as UNIX or Unix-like, e.g. MSYS where you have
      to use configure instead, see the section below)

Here are the steps required using the provided makefiles:

- If you are using gcc-2.95, edit build\msw\config.gcc and set the GCC_VERSION
  variable to "2.95".

- Use the makefile.gcc files for compiling wxWidgets and samples,
  e.g. to compile a debugging version of wxWidgets:
  > cd c:\wx\build\msw
  > make -f makefile.gcc BUILD=debug
  > cd c:\wx\samples\minimal
  > make -f makefile.gcc BUILD=debug
  (See below for more options.)

  Ignore the warning about the default entry point.

- Use the 'strip' command to reduce executable/dll size (note that
  stripping an executable/dll will remove debug information!).

All targets have 'clean' targets to allow removal of object files
and other intermediate compiler files.

Using configure
----------------------------------------------------------------

Instead of using the makefiles, you can use the configure
system to generate appropriate makefiles, as used on Unix
and Mac OS X systems.

Change directory to the root of the wxWidgets distribution,
make a build directory, and run configure and make in this directory.

For example:

  cd $WXWIN
  mkdir build-debug
  cd build-debug
  ../configure --with-msw --enable-debug --enable-debug_gdb --disable-shared
  make
  make install % This step is optional, see note (6) below.
  cd samples/minimal
  make
  ./minimal.exe

Notes:

1. See also the Cygwin/MinGW on the web site or CD-ROM for
   further information about using wxWidgets with these compilers.

2. libwx.a is 100 MB or more - but much less if compiled with no
   debug info (-g0) and level 4 optimization (-O4).

3. If you get a link error under MinGW 2.95.2 referring to:

   EnumDAdvise__11IDataObjectPP13IEnumSTATDATA@8

   then you need to edit the file objidl.h at line 663 and add
   a missing PURE keyword:

   STDMETHOD(EnumDAdvise)(THIS_ IEnumSTATDATA**) PURE;

4. There's a bug in MinGW headers for some early distributions.

   in include/windows32/defines.h, where it says:

   #define LPSTR_TEXTCALLBACKA (LPSTR)-1L)

   it should say:

   #define LPSTR_TEXTCALLBACKA ((LPSTR)-1L)

   (a missing bracket).

5. OpenGL support should work with MinGW as-is. However,
   if you wish to generate import libraries appropriate either for
   the MS OpenGL libraries or the SGI OpenGL libraries, go to
   include/wx/msw/gl and use:

     dlltool -k -d opengl.def -llibopengl.a

   for the SGI DLLs, or

     dlltool -k -d opengl32.def -llibopengl32.a

   and similarly for glu[32].def.

6. The 'make install' step is optional, and copies files
   as follows:

   /usr/local/lib - wxmswXYZd.dll.a and wxmswXYZd.dll
   /usr/local/include/wx - wxWidgets header files
   /usr/local/bin - wx-config

   You may need to do this if using wx-config with the
   default root path.

7. With Cygwin, you can invoke gdb --nw myfile.exe to
   debug an executable. If there are memory leaks, they will be
   flagged when the program quits. You can use Cygwin gdb
   to debug MinGW executables.

8. Note that gcc's precompiled headers do not work on current versions of
   Cygwin. If your version of Cygwin is affected you will need to use the
   --disable-precomp-headers configure option.

OLD VERSIONS:

- Modify the file wx/src/cygnus.bat (or mingw32.bat or mingegcs.bat)
  to set up appropriate variables, if necessary mounting drives.
  Run it before compiling.

- For Cygwin, make sure there's a \tmp directory on your
  Windows drive or bison will crash (actually you don't need
  bison for ordinary wxWidgets compilation: a pre-generated .c file is
  supplied).

- If using GnuWin32 b18, you will need to copy windres.exe
  from e.g. the MinGW distribution, to a directory in your path.


Symantec & DigitalMars C++ compilation
----------------------------------------------------------------

The DigitalMars compiler is a free succssor to the Symantec compiler
and can be downloaded from http://www.digitalmars.com/
   
1. You need to download and unzip in turn (later packages will overwrite
   older files)
      Digital Mars C/C++ Compiler Version 8.40 or later
      Basic utilities
   from http://www.digitalmars.com/download/freecompiler.html

2. Change directory to build\msw and type 'make -f makefile.dmc' to
   make the wxWidgets core library.

3. Change directory to samples\minimal and type 'make -f makefile.dmc'
   to make this sample. Most of the other samples also work.


Note that if you don't have the files makefile.dmc you may create them yourself
using bakefile tool according to the instructions in build\bakefiles\README:

    cd build\bakefiles
    bakefile_gen -f dmars -b wx.bkl
    bakefile_gen -f dmars -b ../../samples/minimal/minimal.bkl


Note that wxUSE_STD_STRING is disabled in wx/string.h for Digital Mars as this
compiler doesn't come with standard C++ library headers by default. If you
install STLPort or another STL implementation, you'll need to edit wx/string.h
and remove the check for Digital Mars in it (search for __DMC__).


16-bit compilation is no longer supported.

Configuring the build
================================================================

So far the instructions only explained how to build release DLLs of wxWidgets
and did not cover any configuration. It is possible to change many aspects of
the build, including debug/release and ANSI/Unicode settings. All makefiles in
build\msw directory use same options (with a few exceptions documented below)
and the only difference between them is in object files and library directory
names and in make invocation command.

Changing the settings
----------------------------------------------------------------

There are two ways to modify the settings: either by passing the values as
arguments when invoking make or by editing build\msw\config.$(compiler) file
where $(compiler) is same extension as the makefile you use has (see below).
The latter is good for setting options that never change in your development
process (e.g. GCC_VERSION or VENDOR). If you want to build several versions of
wxWidgets and use them side by side, the former method is better. Settings in
config.* files are shared by all makefiles (samples, contrib, main library),
but if you pass the options as arguments, you must use same arguments you used
for the library when building samples or contrib libraries!

Examples of invoking make in Unicode debug build (other options described
below are set analogically):

Visual C++:
  > nmake -f makefile.vc BUILD=debug UNICODE=1

Borland C++:
  > make -f makefile.bcc -DBUILD=debug -DUNICODE=1
  (Note that you have to use -D to set the variable, unlike in other make
  tools!)

Watcom C/C++:
  > wmake -f makefile.wat BUILD=debug UNICODE=1

MinGW using native makefiles:
  > mingw32-make -f makefile.gcc BUILD=debug UNICODE=1

MinGW using configure:
  > ./configure --enable-debug --enable-unicode
  (see ./configure --help on details; configure is not covered in this
  section)

Cygwin using configure:
  > ./configure --disable-precomp-headers --enable-debug --enable-unicode
  (use --disable-precomp-headers if Cygwin doesn't support precompiled
  headers)

Brief explanation of options and possible values is in every
build\msw\config.* file; more detailed description follows.

Basic options
----------------------------------------------------------------

BUILD=release
  Builds release version of the library. It differs from default 'debug' 
  in lack of appended 'd' in name of library, does not define __WXDEBUG__
  and not include debug information compiled into object files and the 
  executable.

SHARED=1
  Build shared libraries (DLLs). By default, DLLs are not built
  (SHARED=0).

UNICODE=0
  To build ANSI versions of the libraries, add UNICODE=0 to make invocation
  (default is UNICODE=1). If you want to be able to use Unicode version on
  Windows9x, you will need to set MSLU=1 as well.

  This option affect name of the library ('u' is appended) and the directory
  where the library and setup.h are store (ditto).

WXUNIV=1
  Build wxUniversal instead of native wxMSW (see
  http://www.wxwidgets.org/wxuniv.htm for more information).

Advanced options
----------------------------------------------------------------

MONOLITHIC=1
  Starting with version 2.5.1, wxWidgets has the ability to be built as 
  several smaller libraries instead of single big one as used to be the case
  in 2.4 and older versions. This is called "multilib build" and is the
  default behaviour of makefiles. You can still build single library
  ("monolithic build") by setting MONOLITHIC variable to 1.

USE_GUI=0
  Disable building GUI parts of the library, build only wxBase components used
  by console applications. Note that if you leave USE_GUI=1 then both wxBase
  and GUI libraries are built. If you are building monolithic library, then
  you should set wxUSE_GUI to 1 in setup.h.

USE_OPENGL=1
  Build wxmsw29_gl.lib library with OpenGL integration class wxGLCanvas.
  You must also modify your setup.h to #define wxUSE_GLCANVAS 1. Note that
  OpenGL library is always built as additional library, even in monolithic
  build!

USE_ODBC=1
  Build two additional libraries in multilib mode, one with database
  classes and one with wxGrid database support. You must
  #define wxUSE_ODBC 1 in setup.h

USE_HTML=0
  Do not build wxHTML library. If MONOLITHIC=1, then you must also
  #define wxUSE_HTML 1 in setup.h.

USE_XRC=0
  Do not build XRC resources library. If MONOLITHIC=1, then you must also
  #define wxUSE_HTML 1 in setup.h.

RUNTIME_LIBS=static
  Links static version of C and C++ runtime libraries into the executable, so
  that the program does not depend on DLLs provided with the compiler (e.g.
  Visual C++'s msvcrt.dll or Borland's cc3250mt.dll).
  Caution: Do not use static runtime libraries when building DLL (SHARED=1)!

MSLU=1
  Enables MSLU (Microsoft Layer for Unicode). This setting makes sense only if
  used together with UNICODE=1. If you want to be able to use Unicode version
  on Windows9x, you will need MSLU (Microsoft Layer for Unicode) runtime DLL
  and import lib.  The former can be downloaded from Microsoft, the latter is
  part of the latest Platform SDK from Microsoft (see msdn.microsoft.com for
  details). An alternative implementation of import library can be downloaded
  from http://libunicows.sourceforge.net - unlike the official one, this one
  works with other compilers and does not require 300+ MB Platform SDK update.

DEBUG_FLAG=0
DEBUG_FLAG=1
  If set to 1, define __WXDEBUG__ symbol, append 'd' to library name and do
  sanity checks at runtime. If set to 0, don't do it. By default, this is
  governed by BUILD option (if 'debug', DEBUG_FLAG=1, if 'release' it is 0),
  but it is sometimes desirable to modify default behaviour and e.g. define
  __WXDEBUG__ even in release builds.

DEBUG_INFO=0
DEBUG_INFO=1
  Same as DEBUG_FLAG in behaviour, this option affects whether debugging
  information is included in the executable or not.

TARGET_CPU=AMD64|IA64
  (VC++ only.) Set this variable to build for x86_64 systems. If unset, x86
  build is performed.

VENDOR=<your company name>
  Set this to a short string identifying your company if you are planning to
  distribute wxWidgets DLLs with your application. Default value is 'custom'.
  This string is included as part of DLL name. wxWidgets DLLs contain compiler
  name, version information and vendor name in them. For example
  wxmsw290_core_bcc_custom.dll is one of DLLs build using Borland C++ with
  default settings. If you set VENDOR=mycorp, the name will change to
  wxmsw290_core_bcc_mycorp.dll.

CFG=<configuration name>
  Sets configuration name so that you can have multiple wxWidgets builds with
  different setup.h settings coexisting in same tree. See "Object and library
  directories" below for more information.

COMPILER_PREFIX=<string>
  If you build with multiple versions of the same compiler, you can put
  their outputs into directories like "vc6_lib", "vc8_lib" etc. instead of
  "vc_lib" by setting this variable to e.g. "vc6". This is merely a
  convenience variable, you can achieve the same effect (but different dir
  names) with the CFG option.


Compiler specific options
----------------------------------------------------------------

* MinGW

If you are using gcc-2.95 instead of gcc3, you must set GCC_VERSION to
2.95. In build\msw\config.gcc, change 
> GCC_VERSION = 3
to
> GCC_VERSION = 2.95

* Visual C++

DEBUG_RUNTIME_LIBS=0
DEBUG_RUNTIME_LIBS=1
  If set to 1, msvcrtd.dll is used, if to 0, msvcrt.dll is used. By default
  msvcrtd.dll is used only if the executable contains debug info and
  msvcrt.dll if it doesn't. It is sometimes desirable to build with debug info
  and still link against msvcrt.dll (e.g. when you want to ship the app to
  customers and still have usable .pdb files with debug information) and this
  setting makes it possible.

Fine-tuning the compiler
----------------------------------------------------------------

All makefiles have variables that you can use to specify additional options
passed to the compiler or linker. You won't need this in most cases, but if you
do, simply add desired flags to CFLAGS (for C compiler), CXXFLAGS (for C++
compiler), CPPFLAGS (for both C and C++ compiler) and LDFLAGS (the linker).

Object and library directories
----------------------------------------------------------------

All object files produced during library build are stored in a directory under
build\msw. It's name is derived from build settings and CFG variable and from
compiler name. Examples of directory names:

  build\msw\bcc_msw            SHARED=0
  build\msw\bcc_mswdll         SHARED=1
  build\msw\bcc_mswunivd       SHARED=0, WXUNIV=1, BUILD=debug
  build\msw\vc_mswunivd        ditto, with Visual C++

Libraries and DLLs are copied into subdirectory of lib directory with 
name derived from compiler and static/DLL setting and setup.h into directory
with name that contains other settings:

  lib\bcc_msw
  lib\bcc_lib\msw\wx\setup.h
  lib\bcc_dll
  lib\bcc_dll\msw\wx\setup.h
  lib\bcc_lib
  lib\bcc_lib\mswunivd\wx\setup.h
  lib\vc_lib
  lib\vc_lib\mswunivd\wx\setup.h

Each lib\ subdirectory has wx subdirectory with setup.h as seen above.
This file is copied there from include\wx\msw\setup.h (and if it doesn't exist,
from include\wx\msw\setup0.h) and this is the copy of setup.h that is used by
all samples and should be used by your apps as well. If you are doing changes
to setup.h, you should do them in this file, _not_ in include\wx\msw\setup.h.

If you set CFG to something, the value is appended to directory names. E.g.
for CFG=MyBuild, you'll have object files in
  
  build\msw\bcc_mswMyBuild
  build\msw\bcc_mswdllMyBuild
  etc.

and libraries in

  lib\bcc_libMyBuild
  lib\bcc_dllMyBuild
  etc.

By now it is clear what CFG is for: builds with different CFG settings don't
share any files and they use different setup.h files. This allows you to e.g. 
have two static debug builds, one with wxUSE_SOCKETS=0 and one with sockets
enabled (without CFG, both of them would be put into same directory and there
would be conflicts between the files).

General Notes
=================================================================

- Debugging: under Windows 95, debugging output isn't output in
  the same way that it is under NT or Windows 3.1.
