wxWindows with Watcom

Installation Report

Miscellanous

Hi Watcomer!
This is my second compilation of wxWindows and things are better now. I finally solved the problem that Watcom can't find the entry point for the sample applications. In general i had less problems with this version than with version 2.0.1. I used the Microsoft Visual C++ project files as a source for information and added everything (sources, switches, symbols, ...) from them. Don't forget to set the wxWindows environment variable with

SET WXWIN=<wxWindows Directory>

in your AUTOEXEC.BAT (or User Environment in NT). I've created only Release configurations so far. If you want Debug configurations you may want to create them in a new directory.
Good luck!

Compiler Switches

I don't care much about compiler switches but somebody else maybe would. Below is a table for fastest and smallest code. This is originally from Stephen Howe [TeamSybase] out of Watcom's newsgroup (M2rU0bPN$GA.268@forums.sybase.com). Many thanks to him. Note that the Pentium Pro switches are usable for Pentium II and III too (they're all 686 prozessors, follow the newsgroup thread for more).

Fastest 32-bit Intel Code

Smallest Code

Unfortunately you can't reach all switches when using the IDE. You have to use makefiles instead.

Include Directories

I added the wxWindows include directory '$(%wxwin)\include' to all sources.

Symbols

I defined the following symbols for all sources:
WIN32 NDEBUG _WINDOWS NDEBUG __WINDOWS__ __WXMSW__ __WIN95__ __WIN32__ WINVER=0x0400 STRICT

Additionally i added the symbols 'USE_DEFINE IDE_INVOKED' to file 'dosyacc.c' and the symbol 'FOR_MSW' to all XPM source files. The Visual C++ project further defines 'YY_USE_PROTOS' for file 'dosyacc.c' but Watcom stated this as a redefinition and i leaved that out.

Changes to Source Code

Don't worry. Only a few changes are needed. A note to the #include changes: In the Microsoft Visual C++ project files there're additional include directories defined for some files. This is possible with Watcom too but not a good idea because then the precompiled header is re-created multiple times and the time-saving effect of precompilation is lost.

%wxwin%\src\common\dbtable.cpp

Precompilation header is not the first header in file. I re-arranged the #include's to the default construction (Just look at some other files).

%wxwin%\src\common\dosyacc.c

Changed line 212 from '#include "../common/doslex.c"' to '#include "../src/common/doslex.c"'.

%wxwin%\src\common\imagpng.cpp

Changed line 33 from '#include "png.h"' to '#include "../png/png.h"'.

%wxwin%\src\common\unzip.c

Changed line 22 from '#include "zlib.h"' to '#include "../zlib/zlib.h"'.

%wxwin%\src\common\variant.cpp

Changed line 1499 from 'return (!((*this) == value));' to 'return (!((*this) == (void*)value));' because of an ambiguous error.

%wxwin%\src\msw\ole\automtn

Since version 11.0 Watcom supports the bool keyword so i changed line 542 from
#if defined(__WATCOMC__) || (defined(__VISUALC__) && (__VISUALC__ <= 1000))
to
#if (defined(__WATCOMC__) && (__WATCOMC__ < 1100)) || (defined(__VISUALC__) && (__VISUALC__ <= 1000)) .

Changed line 671 from
#if defined(__WATCOMC__) || (defined(_MSC_VER) && (_MSC_VER <= 1000) && !defined(__MWERKS__) ) //GC
to
#if (defined(__WATCOMC__) && (__WATCOMC__ < 1100)) || (defined(_MSC_VER) && (_MSC_VER <= 1000) && !defined(__MWERKS__) ) //GC .

Warnings

The following warnings are produced during compilation. I haven't corrected them. The wxWindows Team should notice them.
