Hi,
I ran into a bit of trouble compiling the r300 mesa driver. I'm using the
latest r300_driver from cvs with mesa_6_2_branch, which I presume is the
latest release. I'm compiling with gcc 3.4.0 and receive the following
message:
...

radeon_lock.c -o radeon_lock.o
radeon_lock.c: In function `radeonUpdatePageFlipping':
radeon_lock.c:56: error: subscripted value is neither array nor pointer
...
It seems to be falling over on radeon->glCtx->Color._DrawDestMask[0]. On my
machine _DrawDestMask is a GLbitfield (unsigned int). I had to use the
following patches to get it to compile correctly. Is this correct or is
there something wrong with my set up?
Thanks
Kevin
