Fixed bug 2298 - undefined reference to `IID_IUnknown' on cygwin Brian Minton When building static or shared libraries on cygwin 1.7.25 on Windows 7 (32-bit), I get the following link errors: build/.libs/SDL_windowskeyboard.o: In function `UIElementSink_QueryInterface@12': /home/c-bminton/src/SDL/src/video/windows/SDL_windowskeyboard.c:995: undefined reference to `IID_IUnknown' build/.libs/SDL_windowskeyboard.o: In function `IPPASink_QueryInterface@12': /home/c-bminton/src/SDL/src/video/windows/SDL_windowskeyboard.c:1101: undefined reference to `IID_IUnknown' collect2: error: ld returned 1 exit status Makefile:126: recipe for target 'build/libSDL2.la' failed make: *** [build/libSDL2.la] Error 1 -- The libuuid from e2fsprogs is completely unrelated to the w32api UUID.DLL implib. FWIW, any *NIX software that I've seen obviously wants the e2fsprogs version, but if libuuid-devel is installed (in /usr/lib) then you can't link against the w32api implib with a simple -luuid.
