Building problem on Linux
Hello. I've just installed Qt 5.5.0 on my Ubuntu and I have a problem with building any Qt Widget project. Even standard project generated by Qt Creator doesn't work.
I get the following problem:
"cannot find -lGL"
The compiler and debugger are set properly.
Normal C++ applications work properly, just Qt don't.
I don't know how you installed, but make sure you have all the dependencies installed. According to this wiki I think these are the packages for this error:
sudo apt-get install mesa-common-dev
sudo apt-get install libglu1-mesa-dev -y
Thank you very much.
I forgot to install OpenGL libraries.
Now it works, thanks.
