Problems and solution when building GNUstep-gui on windows from svn

[Thierry DELHAISE]

Hi the list,

May be you know but since by googling, I find no message refering to 
this problems on windows I report the problem and give the solution too :


When building gnustep-gui on windows with mingw and msys, there is a 
problem with the installed libjpeg (and headers) with msys :

This give this :

$ make verbose=yes debug=yes
Making all in Source...
make[1]: Entering directory `/home/Thierry 
DELHAISE/Sources/gnustep-gui/Source'
/usr/GNUstep/System/Library/Makefiles/mkinstalldirs .

                from NSBitmapImageRep+JPEG.m:48:
D:/GNUstep/mingw/bin/../lib/gcc/mingw32/3.4.5/../../../../include/jmorecfg.h:227: 
error: conflicting types for 'boolean'
D:/GNUstep/mingw/bin/../lib/gcc/mingw32/3.4.5/../../../../include/rpcndr.h:52:

make[1]: *** [libgnustep-gui.all.library.variables] Error 2
make[1]: Leaving directory `/home/Thierry 
DELHAISE/Sources/gnustep-gui/Source'
make: *** [internal-all] Error 2

The problems is know since may 2007 in mingw(msys) project.

So, to solve the problem edit you'r jmorecfg.h file.( in /mingw/include) 
and add those lines in the first lines (after first comments) :

#if defined(__MINGW32__) && defined(_RPCNDR_H) && !defined(HAVE_BOOLEAN)
#define HAVE_BOOLEAN
#endif

save file and rerun "make"


That's it.

I think using a more recent msys (unstable) should solve the problem too 
, but since I only use "stable" , I can't confirm ... May be others  ?


Best regards
