[Mesa3d-users] ostest1.c osdemo failed with solaris 10 build

[Joe M. <lp...@ya...>]

Hi,

I just downloaded Mesa 7.8.1 and built it on Solaris 10. After getting the libraries to compile, I attempted to verify the build using the demo apps. In particular I use the offscreen rendering mesa libraries provide. However, when I ran the ostest1 demo, the test program fails on to retrieve the correct size for the GL_RED_BITS. It seems to always be returning 8 even though the context was set to a large data type.

In particular the lines of code that are failing include

<snip>
   /* Bind the buffer to the context and make it current */
   if (!OSMesaMakeCurrent( ctx, buffer, type, WIDTH, HEIGHT )) {
      printf("OSMesaMakeCurrent (%d bits/channel) failed!\n", bits);
      free(buffer);
      OSMesaDestroyContext(ctx);
      return 0;
   }

   /* sanity checks */
   glGetIntegerv(GL_RED_BITS, &cBits);
   assert(cBits == bits);
<snip>

where type would be something other than GL_UNSIGNED_BYTE and therefore bits something larger than 8. The assert fails. I have version 7.0.3 running and this test passes. Furthermore, if I remove the sanity check the images come out correct.

I was wondering if anyone has exprienced the same issue? I've built on Solaris 10 using SunStudio 12 compiler. If you need any more information. Please let me know.

Thanks for the help.
