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. +</p> +<p> + In your debugger you can set a breakpoint in _mesa_error() to trap Mesa + errors. +</p> +<p> + There is a display list printing/debugging facility.
