[Ibrahim]

Hi; I installed Qt 5.6 on Ubuntu 16.04. I created a Qt.Labs Controls Application and I run this application but I am getting this code:
/usr/bin/ld: cannot find -lGL Thanks.

@Ibrahim
Have you installed the GL development package? If not, do that.

@kshegunov How I can?

@Ibrahim
Through the package manager. I don't know what exactly you're using on Ubuntu, but I suppose Synaptic should be available. Run it and install the appropriate package.

Hi,

sudo apt-get install libgl1-mesa-dev

and you have GL package in your Ubuntu.
