cannot find -lGL at compil time

[maxime62]

Hi,
It's my first installation of Qt

OS: centos 7 64 bits
GCC: 4.8.5
I also installed CLANG: 3.4.2
I installed QT 5.9.1 and 5.12.2 (same problem with the two)
OpenGL: 3.0

The problem: At compil time (it's a test project with just an empty window), i have this error:

/usr/bin/ld: cannot find -lGL
collect2: error: ld returned 1 exit status
make: *** [testmk_6] Error 1
14:08:31: process "/usr/bin/make" stopped with code 2.
Error during compilation/déploy of project testmk_6 (kit : Desktop Qt 5.12.2 GCC 64bit2)
When executing step "Make"

After research, it seems that lGL library concerns OpenGL, but OpenGL is well installed on my Centos.
My error is not referenced on internet, so i'm stuck.
Thanks for information.

You need to install development packages for OpenGL (and other Qt dependencies, too). I think for CentOS these would be:

sudo yum install mesa-libGLU-devel

Not sure though, I'm not a regular CentOS user (thankfully ;-) It's dinosaur-age state gets on my nerves quickly).

Yes Sierdzio you're right.
It's 'mesa-libGLU-devel'

So in my case (centos): sudo yum install mesa-libGLU-devel

And now my Qt compile works fine.

Thanks.
