"/usr/bin/ld: cannot find -lGL" impossible to compile a Qt project
Since I bought a new computer (I installed Debian stretch with Qt 5.10.1), I can't anymore compile a Qt project. I always end on the following message : "/usr/bin/ld: cannot find -lGL"
After going through many forum, I can already tell you that I already install libglapi-mesa, libgl1-mesa-dev, libgles1-mesa-dev and libgles2-mesa-dev, but I still end in the same compile error.
Of course, if I delete -lGL from the Makefile I can compile but I would like to be able to include this library.
As anyone an idea about what I am missing ?
What Linux distribution are you running ?
What architecture is it ?
I am under Debian 9.4 and my architecture is x86_64.
$ uname -a Linux VTK-industries-salon 4.9.0-6-amd64 #1 SMP Debian 4.9.88-1+deb9u1 (2018-05-07) x86_64 GNU/Linux
Hope it helped !
How did you install Qt ?
On ubuntu i had to do
sudo apt-get install mesa-common-dev
to get the actual headers.
The package mesa-common-dev is already install on my computer.
And I installed Qt trough the installer for linux qt-unified-linux-x64-3.0.4-online.run
sudo apt-get install build-essential libgl1-mesa-dev
jsulm : it is already installed ...
What graphic stack do you have on your machine ?
SGaist : What do you mean ? What is a graphic stack ?
Graphics card, driver, etc.
My graphic card is a "GeForce GTX 1060 6GB"
The driver I installed is "NVIDIA-Linux-x86_64-390.42.run"
I hope it helped ...
Did you check the related libraries ? Where are they installed ?
Run the following command in shell and see if the libraries installed or not in your computer
ldconfig -v | grep -i GL
The library you are looking will be libGL.so . If it is not there install it as follows,
sudo apt-get install libgl1 -y
That will probably fix this issue.
