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,
from ./src/video/ps3/SDL_ps3video.c:32:
./src/video/ps3/SDL_ps3video.h:34:21: error: libspe2.h: No such file or
directory
In file included from ./src/video/ps3/SDL_ps3events_c.h:33,

./src/video/ps3/SDL_ps3video.c:78: error: expected '=', ',', ';', 'asm' or

./src/video/ps3/SDL_ps3video.c: In function 'PS3_VideoInit':
./src/video/ps3/SDL_ps3video.c:167: error: 'spu_data_t' has no member named
'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. ]

| 9 .SH "DESCRIPTION" | |
| 10 .PP | |
| 11 \fBSDL_VideoModeOK\fP returns \fB0\fR if the requested mode is not supported under any bit depth, or returns the bits-per-pixel of the closest available mode with the given width, height and requested \fIsurface\fR flags (see \fI\fBSDL_SetVideoMode\fP\fR)\&. | |
| 12 .PP | |
| 13 The bits-per-pixel value returned is only a suggested mode\&. You can usually request and bpp you want when \fIsetting\fR the video mode and SDL will emulate that color depth with a shadow video surface\&. | |
