OSMesa build error under Ubuntu 24.04 and OsMesa 24.0.5 #411

Open kwaegel opened 2 months ago

kwaegel commented 2 months ago

I'm trying to build under Ubuntu 24.04 with OsMesa (libosmesa6-dev==24.0.5-1ubuntu1), and getting some APIENTRY definition errors. The regular build without any SYSTEM= definitions works fine.

Steps:

git clone https://github.com/nigels-com/glew.git
cd glew/auto
make
cd ..
make SYSTEM=linux-osmesa

Output (after removing some unrelated warnings):

$ make SYSTEM=linux-osmesa
