Installing wxWindows 2.3
------------------------

This is wxWindows 2.3 for Microsoft Windows 3.1, 95, 98 and
Windows NT/Windows 2000. This is an unstable development release.

IMPORTANT NOTE: If you experience problems installing, please
re-read this instructions and other related files (changes.txt,
readme.txt, notes on the Web site) carefully before mailing
wx-users or the author. Preferably, try to fix the problem first and
then send a patch to the author. Please report bugs using the
bug report form on the wxWindows web site.

Unarchiving
-----------

A setup program is provided (setup.exe) to automatically copy files to a
directory on your hard disk. Do not install into a path that contains spaces.
The installation program should set the WXWIN environment variable, which
will be activated when your machine is rebooted. The setup
program contains the following:

- All common, generic and MSW-specific wxWindows source;
- samples;
- documentation in Windows Help format;
- makefiles for most Windows compilers, plus BC++ and
  VC++ IDE files;
- JPEG library source;
- TIFF library source;
- Object Graphics Library;
- Tex2RTF source;
- Dialog Editor binary.

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.

Other add-on packages are available from the wxWindows Web site, such as:

- mmedia.zip. Audio, CD, video access for Windows and Linux.
- ogl3.zip. Object Graphics Library: build network diagrams, CASE tools etc.
- tex2rtf3.zip. Tex2RTF: create Windows Help, HTML, and Word RTF files from
  the same document source.

General installation notes
--------------------------

Alter your WXWIN environment variable to point to this directory.
For Cygwin or Mingw32 compilation, make sure WXWIN contains only
forward slashes.

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

Compilation
-----------

The following sections explain how to compile wxWindows with each supported
compiler.

Visual C++ 4.0/5.0/6.0 compilation
----------------------------------

Using project files (VC++ 5 and 6 only):

1. Unarchive wxWindows-x.y.z-vc.zip, the VC++ 5/6 project
   makefiles (already included in wxMSW-x.y.z.zip and the setup version).
2. Open src/wxvc.dsp, set Debug or Release configuration for
   the wxvc project, and compile. Alternatively, use Batch Build
   to build both Debug and Release configurations.
   This will produce lib/wx.lib (release) and lib/wxd.lib (debug),
   plus various subordinate libraries. It assumes you have
   the TIFF and JPEG source, which is already in the setup
   version of the distribution.
   The project file src/wxvc_dll.dsp will make a DLL version of wxWindow,
   which will go in lib/wxdll.[lib,dll] and lib/wxdlld.[lib,dll].
3. Open a sample project file, choose a configuration such as
   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/SamplesVC.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. Make sure your WXWIN variable is set.
2. If you do NOT have the TIFF or JPEG source code, please remove
   the tiff and jpeg targets from the 'all' target in
   src\msw\makefile.vc. Also ensure the settings in
   include\wx\msw\setup.h specify not to use JPEG or TIFF.
3. Change directory to wx\src\msw. Type:

  'nmake -f makefile.vc'

   to make the wxWindows core library with debug information
   (wx\lib\wxd.lib), then

  'nmake -f makefile.vc cleanall FINAL=1'
  'nmake -f makefile.vc FINAL=1'

   to make the wxWindows core library without debug information
   (wx\lib\wx.lib).
4. Change directory to wx\samples and type 'nmake -f makefile.vc'
   to make all the samples. You can also make them individually.

Makefile notes:

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

  To build the release version using makefiles, add FINAL=1 to your
  nmake invocation, both when building the library and for samples.
  You MUST use the 'cleanall' target (with FINAL=1 or FINAL=0)
  before making a different configuration, because otherwise
  object files used to build the previous configuration may be
  used accidentally for the current configuation. You might see
  this manifested in unexpected link errors or warnings. This problem
  doesn't occur when using project files to build wxWindows.

  Note that the wxWindows core library allows you to have debug
  and release libraries available simultaneously, by compiling the
  objects in different subdirectories, whereas samples must be
  cleaned and re-made to build a different configuration.

To build the DLL version using makefiles:

1. Change directory to wx\src\msw. Type 'nmake -f makefile.vc dll pch'
   to make both a suitable DLL and import library, and to build a
   suitable precompiled header file for compiling applications.
   The resulting libraries are called:

      wx\lib\wx[version].lib(dll) (debug version)
      wx\lib\wx[version].lib(dll) (release version, using FINAL=1)

2. Invoke a sample makefile with 'nmake -f makefile.vc WXUSINGDLL=1'
   (or edit src\makeprog.vc to set WXUSINGDLL to 1 for all
   applications).

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 wxWindows.

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): VC++ 5's optimization code seems to be broken and can
cause both compile and run-time problems: this can be seen when
deleting an object Dialog Editor, in Release mode with optimizations
on. If in doubt, switch off optimisations, although this will result in much
larger executables. It seems possible that the library can be created with
strong optimization, so long as the application is not strongly
optimized. For example, in wxWindows project, set to 'Minimum
Size'. In Dialog Editor project, set to 'Customize: Favor Small
Code' (and no others). This will then work.

Similarly, in VC++ 4, optimization can cause internal compiler
errors, so edit src\makevc.env and change /O1 to /Od before
trying build a release version of the library. Or, type:

nmake -f makefile.vc noopt FINAL=1

and then resume compilation in the normal way. This will build
troublesome files with no optimization. However, there now seems to be
an internal linker error using VC++ 4, in addition to internal
compiler errors for most of the samples, so this version of the compiler
cannot be recommended!

Note (4): 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 (5): for some further notes about upgrading your project
files to be compatible with wxWindows 2.1.14, please see
"Highlights of wxWindows" from the Download page of the
web site or CD-ROM.

Note (6): to create your own IDE files, see the technical note on the
wxWindows web site or CD-ROM, entitled "Compiling wxWindows
applications in the VC++ IDE" (technical note docs/tech/tn0010.htm in the
wxWindows distribution). You can also copy .dsp and .dsw
files from an existing wxWindows sample and adapt them.

Visual C++ 1.5 compilation (16-bit)
-----------------------------------

1. Make sure your WXWIN variable is set, and uses the FAT (short
   name) form.
2. Change directory to wx\src\msw. Type 'nmake -f makefile.dos' to
   make the wxWindows core library.
3. Change directory to a sample, such as wx\samples\minimal, and
   type 'nmake -f makefile.dos'.

Add FINAL=1 to your makefile invocation to build the release
versions of the library and samples.

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

Borland C++ 4.5/5.0 compilation
-------------------------------

Compiling using the makefiles:

1. Make sure your WXWIN variable is set, and uses the FAT (short
   name) form if doing a 16-bit compile.
2. Change directory to wx\src\msw. Type 'make -f makefile.b32' to
   make the wxWindows core library. Ignore the warnings about
   'XXX' not found in library.
3. Change directory to a sample or demo such as samples\minimal, and type
  'make -f makefile.b32'.
4. For release versions, recompile wxWindows and samples using
   'make -f makefile.b32 clean'
   'make -f makefile.b32 FINAL=1'
   for the library and samples.
5. To make and use wxWindows as a DLL, type
   'make -f makefile.b32 clean'
   'make -f makefile.b32 DLL=1'
   and then for each sample,
   'make -f makefile.b32 WXUSINGDLL=1'
   Please note that the samples have not been exhaustively tested
   with this configuration.

Note (1): the wxWindows library and (some) samples compile in 16-bit mode
using makefile.bcc, but at present the wxWindows resource system is switched
off in this mode. See issues.txt for details.

Note (2): unfortunately most samples won't link in 16-bit mode,
because the automatic data segment exceeds 64K. The minimal
sample links and runs, however.

Note (3): the wxWindows makefiles assume byte 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, add a suitable option to the $(CFG) target code
in src/msw/makefile.b32.

Note (4): 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 wxWindows. The same applies if compiling using the IDE.

Note (5): BC++ 4.5 (not 5.0) trips up over jdmerge.c in the JPEG folder;
you will therefore need to set wxUSE_LIBJPEG to 0 in setup.h and remove
the jpeg target from src\msw\makefile.b32, and remove jpeg from
src\makeprog.b32.

Note (6): If using C++Builder 4 and above (BC++ 5.4 and above), change LINK=tlink32 to
LINK=ilink32 in src\makeb32.env. You may also need to disable
wxUSE_LIBJPEG because there is a conflict in the BC++ headers
(actually this problem seems to have gone away with 5.5 and SP1).

Note (7): If you wish debug messages to be sent to the console in
debug mode, edit src\makeb32.env and change /aa to /Tpe in
LINK_FLAGS.

Compiling using the IDE files:

1. Load src\bc32.ide (Release settings)
2. Go to Options|Project... and specify the correct BC++ include and lib path for
   your file structure.
3. Press F9 to compile the wxWindows library.
4. Load samples\bc32.ide.
5. Go to Options|Project... and specify the correct BC++ include and lib path for
   your file structure.
6. Press F9 to compile the samples (build each node separately if
   you prefer, by right clicking and choose Build Node).
7. Run each sample: you may need to run from each sample's directory
   since some (notably the wxHTML samples) look for files
   relative to the working directory.

Note (1): the samples project file contains a selection of
samples, and not all samples. The remaining samples can be made
with the makefiles. See also the demos hierarchy which doesn't
have any BC++ project files yet.

Note (2): to make the png, zlib, jpeg and tiff libraries (needed for
some samples) you need to compile them with bc32.ide.

Note (3): the debug version of the wxWindows library is about 40 MB, and the
release version is around 5 MB.

See also the file docs/tech/tn0007.txt for further instructions and details
of how to create your own project files.

Borland C++ 5.5 compilation
---------------------------

Before compiling wxWindows with Borland C++ 5.5, there are a few 
issues concerning the compiler installation: 

1. The compiler must be installed to a path that does not contain 
   spaces, such as c:\Borland\Bcc55 (in particular, do not install 
   it below "C:\Program Files").

2. Make sure that you downloaded and installed the service pack 1 
   for Borland C++ 5.5.  This SP1 can be downloaded from:
   http://www.borland.com/devsupport/bcppbuilder/file_supplements.html

   IMPORTANT:
   When installing SP1, make sure that you extract (UnZip) the files 
   to the directory where you installed Borland C++ 5.5 (e.g., 
   c:\Borland\Bcc55) with the option "use folder names" selected. 
   This is necessary, to ensure that the files (mostly include files) 
   are extracted to the right directory.

3. Create the following two files in the same directory where you 
   installed Borland C++ 5.5 (e.g., c:\Borland\Bcc55):

   a. bcc32.cfg
      text file containing the following two lines:
      -I"c:\Borland\Bcc55\include"
      -L"c:\Borland\Bcc55\lib"

   b. ilink32.cfg
      text file containing the following line:
      -L"c:\Borland\Bcc55\lib"

   (replace c:\Borland\Bcc55 with the actual path where you installed 
   Borland C++ 5.5)

4. Add the borland BIN directory to your path (e.g., c:\Borland\Bcc55\bin), 
   and define the environment variable BCCDIR=<Borland C++ 5.5 path>
   (e.g., set BCCDIR=c:\Borland\Bcc55)

Compiling wxWindows:

Once the compiler and its service pack are properly installed, you build 
wxWindows using the provided makefile.b32 in the src/msw directory:

a. To build wxWindows in DEBUG mode:

    cd c:\wx2\src\msw
    make -f makefile.b32

    (replace c:\wx2 with the actual path where you installed wxWindows)

b. To build wxWindows in RELEASE mode:

    cd c:\wx2\src\msw
    make -f makefile.b32 FINAL=1   

    (if you had previously built wxWindows, you need to clean all of
    the object and intermediate files.  Before the above make command, 
    run: 'make -f makefile.b32 CLEANALL')

IMPORTANT:
The Service Pack 1 for Borland C++ 5.5 must be installed before wxWindows 
is compiled.  If you compiled wxWindows before, it is advised that you 
re-compile it following the next steps:

    cd c:\wx2\src\msw
    make -f makefile.b32 CLEANALL
    make -f makefile.b32   (or make -f makefile.b32 FINAL=1)

    (replace c:\wx2 with the actual path where you installed wxWindows)

** REMEMBER **

In all of your wxWindows 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 C++Builder compilation
------------------------------

1. Build the wxWindows libraries using the Borland make utility as
   specified in the section called "Borland C++ 4.5/5.0 compilation"
   above. (C++ Builder includes a stand-alone C++ compiler.  For example,
   C++ Builder 4.0 comes with C++ 5.4.)

2. You can build samples using the makefiles as per the
   instructions for BC++ above, or you can follow the instructions
   in docs/tech/tn0004.htm or http://biolpc22.york.ac.uk/wx/bc/ide.html.

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

1. Make sure your WXWIN variable is set, and uses the DOS short
   name form.
2. Change directory to wx\src\msw. Type 'wmake -f makefile.wat' to
   make the wxWindows core library.
3. Change directory to wx\samples\minimal and type 'wmake -f makefile.wat'
   to make this sample. Repeat for other samples of interest.

Note (1): makewat.env uses the odbc32.lib supplied in wxWindows' 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++.
Note (3): if Watcom can't read the precompiled header when
building a sample, try deleting src\msw\watcom.pch and
compiling the sample again.

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

1. Downloaded and unzip wxWindows-x.y.z-cw.zip.
2. Load the make_cw.mcp project in wx\src, and compile.
3. Load the make_cw.mcp project in wx\samples\minimal, and compile.
   Further project files for samples will be available in due
   course.

Note (1): you need CodeWarrior Pro 4 plus the patches to 4.1 from the
Metrowerks Web site.

Note (2): unfortunately these files are not yet up-to-date for the
current release.

Symantec C++ compilation
------------------------

1. Make sure your WXWIN variable is set, and uses the FAT (short
   name) form.
2. Edit setup.h and set wxUSE_DRAG_AND_DROP to 0.
3. Change directory to wx\src\msw. Type 'make -f makefile.sc' to
   make the wxWindows core library.
4. Change directory to wx\samples\minimal and type 'make -f makefile.sc'
   to make this sample.

Note: the minimal sample doesn't link properly ('Error: no
start address').
32-bit compilation only (partially) supported at present, using SC++ 6.1.
Some functionality is missing using this compiler (see makefile).
Add -D__WIN95__ if your SC++ has Windows 95 support, and ignore
Step (2). 16-bit compilation is left as an excercise for the user!

Salford C++ compilation
-----------------------

1. Make sure your WXWIN variable is set, and uses the FAT (short
   name) form.
2. Edit SALFORDDIR and RESOURCEDIR in src/makesl.env as per
   notes.
3. Change directory to wx\src\msw. Type 'mk32 -f makefile.sl all' to
   make the wxWindows core library.
4. Change directory to wx\samples\minimal and type 'mk32 -f makefile.sl'
   to make this sample.

Unfortunately, Salford C++ seems to have problems with its code generation for
operations on objects, as seen in wxFrame::OnMenuHighlight
(minimal sample) or wxWindow::SetValidator (mdi sample). Also the
the debugging version of the library is 90MB, with samples coming in
at 40MB :-) However, wxWindows at least makes a good test suite for
improving the compiler.

Cygwin/Mingw32 compilation
----------------------------------

wxWindows 2 supports Cygwin (formerly GnuWin32) betas and
releases, and Mingw32.

Thanks are due to Keith Garry Boyce (garp@opustel.com), Cygnus
and others for making it all possible.

Both Cygwin and Mingw32 (the minimal distribution of Cygwin) can be used
with the same makefiles.

Here are the steps required:

- Retrieve and install the latest beta of Cygwin, or Mingw32, as per the
  instructions with either of these packages.

- If using Mingw32, you need some extra files to use the wxWindows
  makefiles. You can find these files in ports/mingw32 on the
  wxWindows ftp site or CD-ROM, as extra.zip. These should be extracted
  to the Mingw32 directory. If you have alread downloaded rm, cp, mv
  from elsewhere, you won't need this.

  If using Mingw32 2.95 and below with wxWindows 2.1 or above, you
  must hand-patch with Mingw32-gcc295.patches (located in the
  top-level of the wxWindows 2 installation). Mingw32 2.95.2
  and above contain the fixes already.

- 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 wxWindows compilation: a pre-generated .c file is
  supplied).

- Edit wx/src/makeg95.env and set the MINGW32 variable at the top of
  the file to either 1 (you have Mingw32 or Cygwin 1.x releases) or 0
  (if you have Cygwin betas). If using Mingw32, also set the
  MINGW32VERSION variable appropriately.

- Set your WXWIN variable to where wxWindows is installed.
  *** IMPORTANT: For Cygwin/Mingw32, use forward slashes in the path, not
  backslashes.

- Use the makefile.g95 files for compiling wxWindows and samples,
  e.g.:
  > cd c:\wx\src\msw
  > make -f makefile.g95
  > cd c:\wx\samples\minimal
  > make -f makefile.g95

  Ignore the warning about the default entry point.

- Use the 'strip' command to reduce executable size.

- 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.

- If using GnuWin32 b18, you will need to copy windres.exe
  from e.g. the Mingw32 distribution, to a directory in your path.

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

Notes:

1. See also the Cygwin/Mingw32 on the web site or CD-ROM for
   further information about using wxWindows with these compilers.

2. libwx.a is 48 MB or more - but much less if compiled with no
   debug info (-g0) and level 4 optimization (-O4).

3. There's a bug in Mingw32 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).

4. If there's a problem with the copy or remove commands in
   src/msw/makefile.g95, you may need to change the COPY and
   RM variables in makeg95.env.

5. If there's a problem executing the windres program, try
   commenting out RCPREPROCESSOR in makeg95.env.

6. OpenGL support should work with Mingw32 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.

     http://sourceware.cygnus.com
 - Mingw32 is available at:
     ftp://www.mingw.org

TWIN32 and gcc on Linux
-----------------------

The wxWindows 2 for Windows port may be compiled using
the TWIN32 emulator package from www.willows.com. However,
TWIN32 is by no means finished so this should be taken as
something to think about for the future, rather than
a tool for writing products with.

Use makefile.twn in much the same way as makefile.g95, as
described above. Not all sample makefiles are supplied yet.

For some reason, I found I had to copy TWIN32's Windows resource
compiler (rc) to the current working directory for it to be found.

General Notes
-------------

- Debugging: under Windows 95, debugging output isn't output in
  the same way that it is under NT or Windows 3.1.
  Please see DebugView (bin/dbgview.exe in the distribution), also
  available from http://www.sysinternals.com and on the wxWindows CD-ROM
  under Packages.

- If you are installing wxWindows 2 from CVS, you may find that
  include/wx/msw/setup.h is missing. This is deliberate, to avoid
  developers' different setup.h configurations getting confused.
  Please copy setup0.h to setup.h before compiling. Also, read
  the BuildCVS.txt for other hints.
