wxWindows with Watcom

Installation Report

Miscellanous

Hi Watcomer!
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.

Note: My system configuration has changed since 2.1.11. I'm now using Pentium III switches.

Please send me comments, suggestions or corrections!
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 '..\..\include' to all sources.

Symbols

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

Additionally i added the symbols 'USE_DEFINE IDE_INVOKED' to file 'dosyacc.c'. 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%\include\msw\setup.h

Disable all Watcom related #undef's because everthing compiles (i've already reported this to the wxWindows Team).

%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\imagjpeg.cpp

Added in line 32 '#define HAVE_BOOLEAN'.

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

%wxwin%\src\common\imagpng.cpp

Changed line 32 from '#include "png.h"' to '#include "../png/png.h"'.

%wxwin%\src\common\imagtiff.cpp

Changed line 32 from '#include "tiff.h"' to '#include "../tiff/tiff.h"'.

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

%wxwin%\src\common\unzip.c

Changed line 24 from '#include "zlib.h"' to '#include "../zlib/zlib.h"'.

%wxwin%\src\common\unzip.h

Changed line 56 from '#include "zlib.h"' to '#include "../zlib/zlib.h"'.

%wxwin%\src\common\variant.cpp

Changed line 1512 from 'return (!((*this) == value));' to 'return (!((*this) == (void*)value));' because of an ambiguous error.

%wxwin%\src\common\wfstream.cpp

Change constructor (line 168) to

wxFileStream::wxFileStream(const wxString& fileName)
: wxFileInputStream(fileName) {
   wxFileOutputStream::m_file = wxFileInputStream::m_file;
}
      

wxFFileStream::wxFFileStream(const wxString& fileName)
: wxFFileInputStream(fileName) {
   wxFFileOutputStream::m_file = wxFFileInputStream::m_file;
}
      

%wxwin%\src\png\png.h

Changed line 163 from '#include "zlib.h"' to '#include "../zlib/zlib.h"'.

%wxwin%\src\jpeg\jconfig.h

Added the following in line 59:

#elif defined(__WATCOMC__)
#define INLINE
      

Warnings

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

y_tab.c(516): Warning! W118: Label 'yyerrlab' has been defined but not referenced
y_tab.c(516): Warning! W118: Label 'yynewerror' has been defined but not referenced

Result

Sizes

The table below shows some executable/library sizes to check your own compilation. Note: This values may differ if you use different compiler switches.

Compilation Time (All libraries)

about 10 Minutes (Intel Pentium III 550 MHz, 128 MByte RAM)
