Hash :eb5eb046 Message :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.
