Yes fine. BTW: are you aware of this page:

https://grasswiki.osgeo.org/wiki/Compile_and_Install

The closest might be
https://grasswiki.osgeo.org/wiki/Compile_and_Install#Scientific_Linux

which I have used for many years.

Is there a chance to install the RPM which contains GL/gl.h?
On my Fedora box that is the mesa-libGL-devel RPM.

ok, for fun I have removed the OpenGL headers on my Fedora box (along
with some dependent packages) and tried to reproduce your problem. So
I ended up with

  Cairo support:              no
...
  OpenGL support:             no
...
  wxWidgets support:          no

Means, I used for configure:

...
  --with-cairo=no \
  --with-wxwidgets=no \
  --with-opengl=no \
...

Compiling it as that gave me no errors at all.

Yes. Again, it should only be an RPM.

Please check which configure switches you used.

Maybe send the full configure command to me off-list, in order to take
a look. And also config.log.

Best,
Markus
