I did some testing: Installing a SDL.framework in /Library/Frameworks(*) and a cmake package that has CMAKE_FIND_FRAMEWORK=FIRST, I tried to build at random one of Fink's game packages that use sdl, violetland-0.2.10-1002. It failed on linking the executable, with some undefined symbols. Without trying to go to the bottom of the failure, I strongly suspect that the reason is that it finds a mixture of the sdl framework with some other sdl parts from Fink: costabel% grep -i sdl /sw/src/fink.build/violetland-0.2.10-1002/violetland-v0.2.10/CMakeCache.txt SDLIMAGE_INCLUDE_DIR:PATH=/sw/include/SDL SDLIMAGE_LIBRARY:FILEPATH=/sw/lib/libSDL_image.dylib SDLMIXER_INCLUDE_DIR:PATH=/sw/include/SDL SDLMIXER_LIBRARY:FILEPATH=/sw/lib/libSDL_mixer.dylib SDLTTF_INCLUDE_DIR:PATH=/sw/include/SDL SDLTTF_LIBRARY:FILEPATH=/sw/lib/libSDL_ttf.dylib SDL_INCLUDE_DIR:PATH=/Library/Frameworks/SDL.framework/Headers //Where the SDL Library can be found SDL_LIBRARY:STRING=/Library/Frameworks/SDL.framework;-framework Cocoa SDL_LIBRARY_TEMP:INTERNAL=/Library/Frameworks/SDL.framework;-framework Cocoa With the cmake package that has CMAKE_FIND_FRAMEWORK=LAST, it builds without any problem. I suspect the same problems will arise with other Fink packages. Thus the question is whether we want to protect all cmake-using Fink packages individually against stuff that might or might not be installed in /Library/Frameworks (and system stuff in /System/Library/Frameworks that we might not want to link against) or have a slightly non-standard default that does this protection globally. In your case, I suppose setting some cmake flags, like SDL_INCLUDE_DIR and SDL_LIBRARY, to point to the framework in ~/Library/Frameworks should do the trick. (*) Placing the framework in ~/Library/Frameworks does not expose it to cmake during Fink builds, because then the $HOME environment variable is set differently, so "~" does not expand to /Users/costabel, but to something like /var/folders/I5/I5XYEUYz2RWfpk+8ZKtEU++++TI/-Tmp-/fink-build-HOME.gm9A4gNcfa -- Martin ------------------------------------------------------------------------------ Sell apps to millions through the Intel(R) Atom(Tm) Developer Program Be part of this innovative community and reach millions of netbook users worldwide.
