Resolving the "can't find -lGL" Error in Qt on Ubuntu
When compiling a Qt project, you may encounter the error message "cannot find -lGL." This error typically indicates that a required library for OpenGL support is missing.
Solution:
To resolve this issue, you need to install the "libgl1-mesa-dev" package, which contains the necessary OpenGL development libraries:
