Newly created project doesnt work: cannot find -lGL: no such file or directory

[sebi03]

Just installed Qt 6.7.0 and wanted to make a UI for a simple c++ app. I create a qt desktop project and without touching anything else it fails to build. Am i missing a kit or something ? I tried making a project with qmake and cmake and they both give similar errors.

Would help if you stated which platform/OS you are on (and possibly which compiler).
Depending on your reply to @Christian-Ehrlicher, if you are Linux what libGL* files are on your system?

@JonB i am on ubuntu 22.04 and i am using the compiler provided with the installation. can you elaborate on the libGL files as i dont know what those are. my replies might be slow because i am allowed one post every 10 mins as i just made the account

Note: Just installing the above-mentioned mesa-common-dev kit is not sufficient for more recent Ubuntu versions. Based on a comment in the Qt forum[1] an additional package needs installation. Execute following command:

sudo apt-get install libglu1-mesa-dev -y

after installing libglu it worked! thank you all guys !

This issue is so common on this forum that it would deserve a pinned link somewhere IMO.
