The meson build keys -DDEBUG on the builtype, debug or debugoptimized you get -DDEBUG, anything else, you don't. The way mesa is setup if you don't have -DNDEBUG you have to have -DDEBUG or asserts happen for member of structures that don't exist. I'm not dead set on debug as the default buildtype, it's what we have ATM though. I asked around here and the feeling was that builtype debug by default was a feature. If the larger community disagrees we can change it. Dylan
