                How to build the sources from SVN\r
------------------------------------------------------------------------\r
\r
Please use the install.txt files in docs/gtk, docs/msw, docs/motif, docs/mac\r
etc. alongside these instructions.\r
\r
I) Windows using plain makefiles\r
----------------------------------------\r
\r
a) If using Microsoft Visual C++ 5.0 or 6.0\r
\r
Ensure that the command-line compiler and tools (including\r
nmake) are installed and ready to run.  Depending on your\r
installation there may be a batch file (commonly named VCVARS32.BAT)\r
that needs to be run to set correct environment variables and PATH entries.\r
\r
Continue with item c) below.\r
\r
\r
b) If using the MinGW or Cygwin compilers\r
\r
You can get MinGW from  http://www.mingw.org/\r
\r
Cygwin is available at  http://www.cygwin.com/\r
\r
If you are using Cygwin or MinGW together with the MSYS environment, you\r
can build the library using configure (see "Unix ports" and\r
"Windows using configure" below). You can also\r
build wxWidgets without configure using native makefile, but only with\r
MinGW. Using Cygwin together with Windows makefile is no longer supported.\r
\r
If building with MinGW without configure:\r
\r
-> Set your path so that it includes the directory\r
   where your compiler and tools reside\r
\r
-> Make sure you have GNU Make installed. It must be Windows native version.\r
   Download it from http://www.mingw.org, the executable will be called\r
   mingw32-make.exe.\r
\r
-> Modern version of MinGW is required; preferably MinGW 2.0 (with gcc3),\r
   but MinGW with gcc-2.95.3 will suffice. If you are using 2.95, you will\r
   have to change variable GCC_VERSION in config.gcc (see msw/install.txt\r
   for details).\r
\r
If using configure, Unix instructions apply.\r
\r
\r
c) Build instructions\r
\r
Assuming that you installed the wxWidgets sources into c:\wxWidgets:\r
\r
-> Copy c:\wxWidgets\include\wx\msw\setup0.h\r
   to   c:\wxWidgets\include\wx\msw\setup.h\r
-> Edit c:\wxWidgets\include\wx\msw\setup.h to choose\r
   the features you would like to compile wxWidgets with[out].\r
\r
   and std iostreams are disabled with\r
   #define wxUSE_STD_IOSTREAM   0\r
\r
-> type: cd c:\wxWidgets\build\msw\r
-> type: make -f makefile.gcc  (if using GNU tools)\r
or type: nmake -f makefile.vc   (if using MS VC++)\r
etc.\r
\r
   See also docs/msw/install.txt for additional compilation options.\r
\r
d) Borland (including free command line tools)\r
   Download tools from http://www.borland.com/downloads/\r
\r
   See docs/msw/install.txt for details; in brief:\r
\r
-> type cd c:\wxWidgets\build\msw\r
-> type make -f makefile.bcc\r
\r
You can customize many things in the build process, detailed description is\r
in docs/msw/install.txt.\r
\r
\r
II) Unix ports\r
--------------\r
\r
Building wxGTK or wxMotif completely without configure\r
won't ever work, but there is now a new makefile system\r
that works without libtool and automake, using only\r
configure to create what is needed.\r
\r
In order to create configure, you need to have the\r
GNU autoconf package (version > 2.54) installed\r
on your system and type run "autoconf" in the base\r
directory (or run the autogen.sh script in the same\r
directory, which just calls autoconf). Note that you usually don't\r
need to do this because configure is included in SVN.\r
\r
Set WXWIN environment variable to the base directory such\r
as ~/wxWidgets (this is actually not really needed).\r
\r
-> type: export WXWIN=~/wxWidgets\r
-> type: md mybuild\r
-> type: cd mybuild\r
-> type: ../configure --with-motif\r
or type: ../configure --with-gtk\r
-> type: make\r
-> type: su <type root password>\r
-> type: make install\r
-> type: ldconfig\r
-> type: exit\r
\r
Call configure with --disable-shared to create a static\r
library. Calling "make uninstall" will remove the installed\r
library and "make dist" will create a distribution (not\r
yet complete).\r
\r
III) Windows using configure\r
----------------------------------------\r
\r
wxWidgets can be built on Windows using MSYS (see\r
http://www.mingw.org/), which is a POSIX build environment\r
for Windows. With MSYS you can just ./configure && make (see also VII,\r
Unix->Windows cross-compiling using configure).\r
\r
Of course, you can also build the library using plain makefiles (see\r
section I).\r
\r
IV) Classic MacOS using CodeWarrior (eg MacOS 8.x/9.x)\r
----------------------------------------\r
\r
Refer to the readme.txt and install.txt files in docs/mac to build\r
wxWidgets under Classic Mac OS using CodeWarrior.\r
\r
If you are checking out the SVN sources using svn under Mac OS X and\r
compiling under Classic Mac OS:\r
\r
- make sure that all text files have a Mac OS type of 'TEXT' otherwise\r
  CodeWarrior may ignore them. Checking out the SVN sources using svn\r
  under Mac OS X creates untyped files which can lead to compilation\r
  errors under CodeWarrior which are hard to track down.\r
\r
- convert the xml files to CodeWarrior binary projects using the supplied\r
  AppleScript in docs/mac (M5xml2mcp.applescript for CodeWarrior 5.3)\r
\r
V) MacOS X using configure and the Developer Tools\r
----------------------------------------\r
\r
You need to have the Developer Tools installed. If this is not the case,\r
you will need to register at the Apple Developer web site (this is a free\r
registration) in order to download the Developer Tools installer.\r
\r
In order to create configure, you need to have the\r
GNU autoconf package (version >= 2.54) installed\r
on your system and type run "autoconf" in the base\r
directory (or run the autogen.sh script in the same\r
directory, which just calls autoconf).\r
\r
-> type: mkdir macbuild\r
-> type: cd macbuild\r
-> type: ../configure --with-mac\r
or type: ../configure\r
-> type: make\r
\r
VI) OS/2\r
----------------------------------------\r
No notes.\r
\r
VII) Unix->Windows cross-compiling using configure\r
--------------------------------------------------\r
\r
First you'll need a cross-compiler; linux glibc binaries of MinGW and\r
Cygwin (both based on egcs) can be found at\r
ftp://ftp.objsw.com/pub/crossgcc/linux-x-win32. Alternative binaries,\r
based on the latest MinGW release can be found at\r
http://members.telering.at/jessich/mingw/mingwcross/mingw_cross.html\r
Otherwise you can compile one yourself.\r
\r
[ A Note about Cygwin and MinGW: the main difference is that Cygwin\r
binaries are always linked against cygwin.dll. This dll encapsulates most\r
standard Unix C extensions, which is very handy if you're porting unix\r
software to windows. However, wxMSW doesn't need this, so MinGW is\r
preferable if you write portable C(++). ]\r
\r
You might want to build both Unix and Windows binaries in the same source\r
tree; to do this make subdirs for each e.g. unix and win32. If you've\r
already build wxWidgets in the main dir, do a 'make distclean' there,\r
otherwise configure will get confused. (In any case, read the section 'Unix\r
using configure' and make sure you're able to build a native wxWidgets\r
library; cross-compiling errors can be pretty obscure and you'll want to be\r
sure that your configure setup is basically sound.)\r
\r
To cross compile the windows library, do\r
-> cd win32\r
(or whatever you called it)\r
Now run configure. There are two ways to do this\r
-> ../configure --host=i586-mingw32 --build=i586-linux --with-mingw\r
where --build= should read whatever platform you're building on. Configure\r
will notice that build and host platforms differ, and automatically prepend\r
i586-mingw32- to gcc, ar, ld, etc (make sure they're in the PATH!).\r
The other way to run configure is by specifying the names of the binaries\r
yourself:\r
-> CC=i586-mingw32-gcc CXX=i586-mingw32-g++ RANLIB=i586-mingw32-ranlib \\r
   DLLTOOL=i586-mingw32-dlltool LD=i586-mingw32-ld NM=i586-mingw32-nm \\r
   ../configure --host=i586-mingw32 --with-mingw\r
\r
(all assuming you're using MinGW)\r
By default this will compile a DLL, if you want a static library,\r
specify --disable-shared.\r
\r
Type\r
-> make\r
and wait, wait, wait. Don't leave the room, because the minute you do there\r
will be a compile error :-)\r
\r
NB: if you are using a very old compiler you risk to get quite a few warnings\r
    about "ANSI C++ forbids implicit conversion from 'void *'" in all places\r
    where va_arg macro is used. This is due to a bug in (some versions of)\r
    MinGW headers which may be corrected by upgrading your compier,\r
    otherwise you might edit the file\r
\r
    ${install_prefix}/lib/gcc-lib/i586-mingw32/egcs-2.91.57/include/stdarg.h\r
\r
    (instead of egcs-2.91.57 you may have something different), searching for\r
    the lines\r
\r
/* Define __gnuc_va_list.  */\r
\r
#ifndef __GNUC_VA_LIST\r
#define __GNUC_VA_LIST\r
#if defined(__svr4__) || defined(_AIX) || defined(_M_UNIX) || defined(__NetBSD__)\r
typedef char *__gnuc_va_list;\r
#else\r
typedef void *__gnuc_va_list;\r
#endif\r
#endif\r
\r
    and adding "|| defined(_WIN32)" to the list of platforms on which\r
    __gnuc_va_list is char *.\r
\r
If this is successful, you end up with a wx23_2.dll/libwx23_2.a in win32/lib\r
(or just libwx_msw.a if you opted for a static build).\r
Now try building the minimal sample:\r
\r
-> cd samples/minimal\r
-> make\r
\r
and run it with wine, for example (or copy to a Windows box)\r
-> wine minimal.exe\r
\r
If all is well, do an install; from win32\r
-> make install\r
\r
Native and cross-compiled installations can co-exist peacefully\r
(as long as their widget sets differ), except for wx-config. You might\r
want to rename the cross-compiled one to i586-mingw32-wx-config, or something.\r
\r
Cross-compiling TODO:\r
---------------------\r
- resource compiling must be done manually for now (should/can we link the\r
default wx resources into libwx_msw.a?) [ No we can't; the linker won't\r
link it in... you have to supply an object file ]\r
- static executables are HUGE -- there must be room for improvement.\r
