Fixed bug #895
Markus Rothe 2009-12-07 09:32:46 PST
Check if libspe2 is available
Building on PowerPC64 results in:
[...]
In file included from ./src/video/ps3/SDL_ps3events_c.h:33,

./src/video/ps3/SDL_ps3video.h:34:21: error: libspe2.h: No such file or
directory

'program'
./src/video/ps3/SDL_ps3video.c:167: error: 'fb_writer_spu' undeclared (first
use in this function)
[...]
The problem is that the ps3 video driver is being build regardless if libspe2
is installed or not. The attached patch fixes this problem.
[ Note: The other headers that are being checked for are coming from the linux
headers package on powerpc64. As a result these are also available if you're on
a generic powerpc64 machine and not a PS3 only. ]
