"/usr/bin/ld: cannot find -lGL" impossible to compile a Qt project

[Wotan]

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 ?

[mrjj]

Hi
On ubuntu i had to do
sudo apt-get install mesa-common-dev
to get the actual headers.

[Wotan]

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

@Wotan See here: https://doc.qt.io/qt-5/linux.html
You need to install

sudo apt-get install build-essential libgl1-mesa-dev

[Wotan]

jsulm : it is already installed ...

[SGaist]

What graphic stack do you have on your machine ?

[Wotan]

SGaist : What do you mean ? What is a graphic stack ?

[SGaist]

Graphics card, driver, etc.

[Wotan]

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 ?

[Sifu]

@Wotan said in "/usr/bin/ld: cannot find -lGL" impossible to compile a Qt project:

GL

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.
