Debugging Tips
Debugging Tips
Normally Mesa (and OpenGL) records but does not notify the user of
errors. It is up to the application to call
glGetError to check for errors. Mesa supports an
environment variable, MESA_DEBUG, to help with debugging. If
MESA_DEBUG is defined, a message will be printed to stdout whenever
an error occurs.
More extensive error checking is done when Mesa is compiled with the
DEBUG symbol defined. You'll have to edit the Make-config file and
add -DDEBUG to the CFLAGS line for your system configuration. You may
also want to replace any optimization flags with the -g flag so you can
use your debugger. After you've edited Make-config type 'make clean'
before recompiling.
In your debugger you can set a breakpoint in _mesa_error() to trap Mesa
errors.
There is a display list printing/debugging facility. See the end of
src/dlist.c for details.
