Greetings,
When I try to compile test programs I get the following list of undefined
references:
/usr/local/sdl/sdl-1.2.7/lib/libSDL.so: undefined reference to
_MMX_UbluRGB' /usr/local/sdl/sdl-1.2.7/lib/libSDL.so: undefined reference to_MMX_Vred5x5’

collect2: ld returned 1 exit status
What might be the cause of this?
Best regards,

Some background:
I am attempting to build SDL-1.2.7 for linux.
I am running kernel-2.6.6 and gcc-3.4.0.
In order to get sdl to successfully build with gcc-3.4.0, I had to apply
this patch…
