I tried to compile and debug the program, and all works fine here. I have a nvidia card and use the binary drivers from them. Anyways, here is some information from the dri-devel mailing list: <quote> Jacek Popawski wrote: > Sometimes when using gdb with my program I see error: > Program received signal SIGFPE, Arithmetic exception. > [Switching to Thread 1024 (LWP 2340)] > 0x405cdcfb in _mesa_test_os_sse_exception_support () from /usr/X11R6/lib/modules/dri/tdfx_dri.so > > This is not my program fault, because there is same message with glxgears and > other OpenGL applications.

It's a normal part of start-up. We found that the only reliable way to detect SSE support (both CPU-wias and OS-wise) is to try an SSE instruction and see if an exception is raised. -Brian </quote> HTH, Michael -- [EMAIL PROTECTED] mailing list
