Fixed bug #943
Ozkan Sezer 2010-02-06 12:31:06 PST
Hi:
Here are some small fixes for compiling SDL against mingw-w64.
(see http://mingw-w64.sourceforge.net/ . Despite the name, it
supports both win32 and win64.) Two patches, one for SDL-1.2
and one for SDL-1.3 attached.
src/audio/windx5/directx.h and src/video/windx5/directx.h (both
SDL-1.2 and SDL-1.3.) I get compilation errors about some union
not having a member named u1 and alike, because of other system
headers being included before this one and them already defining
DUMMYUNIONNAME and stuff. This header probably assumes that those
stuff are defined in windef.h, but mingw-w64 headers define them
in _mingw.h. Easily fixed by moving NONAMELESSUNION definition to
the top of the file. SDL_dx5yuv.c (SDL-1.2-only) also needs to
include the header before SDL_video.h to avoid the same problem.
src/thread/win32/SDL_systhread.c (both SDL-1.2 and SDL-1.3.) :
The __GNUC__ case for pfnSDL_CurrentBeginThread is 32-bit centric
because _beginthreadex returns uintptr_t, not unsigned long which
is 32 bits in win64. Changing the return type to uintptr_t fixes
it.
Hope these are useful. Thanks.
