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

[Pierre-Henri Trivier]

For info, the -I/usr/include was added by AX_BOOST_BASE. I fixed it by setting --with-boost and --with-boost-libdir at configure time. 

As for the PKG_CHECK_MODULES, I can't use it because the version of SDL_image and SDL_mixer I have on my machine do not provide a pkg-config script. 


Also, when using PKG_CHECK_MODULES to cross compile, I don't get all the flags I need with SDL_image_LIBS and stuff (I have to manually add -jpeg and stuff).

Finally, I don't know if this is the proper place to ask, but I can't seem to get the proper set of lib flags needed to cross-compile against SDL_mixer.... with the following line : 

i686-pc-mingw32-g++  -g -O2   -o ube.exe ube.o libube-client.a ../engine/libube-engine.a ../common/libube-common.a -lpopt -lSDL_mixer -logg -lvorbis -lsmpeg -L/home/phtrivier/src/mingw-cross-env-trunk/usr/i686-pc-mingw32/lib -lmingw32 -lSDLmain -lSDL -lwinmm -mwindows -liconv -lm -luser32 -lgdi32 -lwinmm -ldxguid -lSDL_image -lpng -ltiff -ljpeg -lz -lSDL_ttf -lfreetype -llua  -lm -lintl -liconv

I still get : 

/home/phtrivier/src/mingw-cross-env-trunk/usr/i686-pc-mingw32/lib/libSDL_mixer.a(dynamic_ogg.o): In function `Mix_InitOgg':

Anyway, thanks for the help ...

That isn't necessary. I already found some issues. I don't want to
go into details unless someone is really interested at that. In short:

   * Don't use AM_PATH_SDL.
   * Try to avoid AC_SEARCH_LIBS and AC_CHECK_LIBS.
   * Use PKG_CHECK_MODULES wherever possible.

In your concrete case, you can check for SDL, SDL_image and SDL_mixer
via pkg-config. The only problem is SDL_ttf which doesn't provide a
pkg-config entry, so it has to be checked the "old way".

So I recommend to put into your configure.ac something along the lines:

   PKG_CHECK_MODULES([SDL],       [sdl >= 1.2.13], ...SUCCESS..., ...FAILURE...)
   PKG_CHECK_MODULES([SDL_image], [SDL_image],     ...SUCCESS..., ...FAILURE...)
   PKG_CHECK_MODULES([SDL_mixer], [SDL_mixer],     ...SUCCESS..., ...FAILURE...)
   AC_CHECK_LIB(SDL_ttf, TTF_OpenFontRW, ...SUCCESS..., ...FAILURE...)

It should be sufficient to do:

   ./configure --host=i686-pc-mingw32

Have a look at the tutorial "Step 5a" for more information.
