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.

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.

%wxwin%\src\tiff\tif_lzw.c

I've disabled lines 40, 41, 42 and 44 because my Watcom C++ likes long filenames.

%wxwin%\src\tiff\tif_predict.c

I've disabled lines 34, 35, 36 and 38 because my Watcom C++ likes long filenames.

%wxwin%\samples\opengl\isosurf\isosurf.h:24:

Changed constructor parameter from 'const wxWindowID id = -1' to 'wxWindowID id = -1' because it's not const in the .cpp file, const makes little sense with call by value and Watcom complains about it.

Warnings

Some warnings are produced during compilation. I haven't corrected them because they're not very dangerous.

Need for Speed?

If you re-compile the library quite often you may wish to speed up compilation by using precompiled header for all core library .cpp files (.cpp files in wx.lib). You'll find support for precompiled header in all wxWindows related source files but IMHO it makes no sense for e.g. zlib.lib because it compiles already very fast. For Watcom the whole thing only works well if the compiler settings are the same for all source files. Otherwise the precompiled header will be re-created every time the compiler settings change (if e.g. the include path changes). To optimize the usage of pre-compiled headers please remove all additional include path switches for individual .cpp files in wx.lib and apply the following changes:

%wxwin%\src\common\dosyacc.c

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

%wxwin%\src\common\imagjpeg.cpp

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

%wxwin%\src\common\imagpng.cpp

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

%wxwin%\src\common\imagtiff.cpp

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

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

%wxwin%\src\common\unzip.c

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

%wxwin%\src\common\unzip.h

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

%wxwin%\src\png\png.h

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