Re: Fwd: [Mingw-cross-env-list] Error compiling source file including <string.h>

[Pierre-Henri Trivier]

I'm progressing.In the development release, I can use PKG_CHECK_MODULES to help locate some of the libs

In my configure.ac : 

PKG_CHECK_MODULES([SDL], [sdl >= 1.2.13], , )

PKG_CHECK_MODULES([SDL_image], [SDL_image])

PKG_CHECK_MODULES([SDL_mixer], [SDL_mixer])

AC_SEARCH_LIBS(TTF_OpenFontRW, SDL_ttf, , 

      AC_MSG_WARN([*** Unable to find SDL_ttf library.

         Are you cross compiling ?]))

In my Makefile.am : 

SDL_TTF_LIBS = -lSDL_ttf -lfreetype

ube_LDADD=libube-client.a \

../engine/libube-engine.a \

../common/libube-common.a \

-lpopt \

$(SDL_LIBS) $(SDL_image_LIBS) $(SDL_TTF_LIBS) $(SDL_mixer_LIBS)  \

$(LUA_LIB) $(LIBINTL) 

(I still have to define SDL_TTF_LIBS as it does not have a pkg config yet)

Then i get the (rather big) link line (cut down for clarity) :

 i686-pc-mingw32-g++  -g -O2   -o ube.exe ube.o libube-client.a ../engine/libube-engine.a ../common/libube-common.a 

-lpopt 

-mwindows -L/home/phtrivier/sandbox/mingw-cross-env-trunk/usr/i686-pc-mingw32/lib 

-lSDL_image -ltiff -ljpeg -lmingw32 -lSDLmain -lSDL -liconv -lm -luser32 -lgdi32 -lwinmm -ldxguid -lpng14 -lz 

-lSDL_ttf -lfreetype 

-mwindows -L/home/phtrivier/sandbox/mingw-cross-env-trunk/usr/i686-pc-mingw32/lib 

-lSDL_mixer -lmikmod -lpthread -lws2_32 -lsmpeg -lstdc++ -lmingw32 

-lSDLmain -lSDL -liconv -luser32 -lgdi32 

-lwinmm -ldxguid -lvorbisfile -lvorbis -lm -logg   

-llua  -lm -lintl -liconv

And I still get a link error : 

/home/phtrivier/sandbox/mingw-cross-env-trunk/usr/i686-pc-mingw32/lib/libSDLmain.a(SDL_win32_main.o): In function `console_main':

/home/phtrivier/sandbox/mingw-cross-env-trunk/tmp-sdl/SDL-1.2.14/./src/main/win32/SDL_win32_main.c:315: undefined reference to `_SDL_main'

Which is rather depressing as SDL_main is linked twice ;)

In another thread you mentionned you've been able to cross compile an app against SDL ... is this the proper link line I should get ? Or am I missing something again ? 

Thanks again for the help ! 

Regards

Okay, that's good to know.

Yes, it's a pity. :-(
I also just figured it out. See:

http://lists.gnu.org/archive/html/mingw-cross-env-list/2010-02/msg00056.html

This problem should be fixed now. Please upgrade to the latest
development version. Then the command

   i686-pc-mingw32-pkg-config SDL_image --libs

should produce the correct output. If it doesn't, please report
it to us, because in that case it's a bug in mingw-cross-env.

Greets,
