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 in DEBUG builds
|
|
(``--buildtype debug`` for Meson).
|
|
|
|
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.
