OK, taking small steps here, what is OSMesa, and want is Mesa? Utkarsh and I had this discussion, but I never understood the difference.
Having just googled the difference, If I understand correctly, OSMesa actually means Off Screen Mesa, and is compiled into Mesa. Otherwise, you get Mesa – software rendering, but into a GLX window? You are correct – I am not building OSMesa. Thus, my problem?

User has tried running a build I did – which attaches to Mesa – and has –use-offscreen-rendering turned on, and is running pvbatch. Same error. Any ideas? Thanks, Alan
