I'm using Ubuntu Mate and I know I have to instal libgl1-mesa-dev if I want to develop OpenGL programs. And for a very rare case, I need to do this:
sudo ln -s /usr/lib/x86_64-linux-gnu/libGL.so.1 /usr/lib/libGL.so
I didn't try this command
sudo ln -s /usr/lib/x86_64-linux-gnu/libGL.so.1 /usr/lib/libGL.so
because the x86_64-linux-gnu folder and the libGL.so.1 file don't exist.
but I have fixed it with install
sudo dnf install mesa-libGLU.i686
sudo dnf install mesa-libGL-devel
but this error still appears when lazarus loads
Error: fpc.cfg is missing.
can anyone help?
