error: cannot find -lGL [SOLVED]

[zeroptr]

Hi all,

I installed Ubuntu 15.04 amd64 to my virtual machine and qt from the web site's linux online installer..

I get some errors but I corrected by intalling mesa-dev packages.. then..
when I create a new qt widgets application or a qtwidgets sample the compiler always says

: error: cannot find -lGL
: error: collect2: error: ld returned 1 exit status

what's wrong I googled this but I cannot find a solution ??

I also encountered the problem. you just run the flowing orders:
sudo apt-get install libqt4-dev
or
sudo apt-get install libgl1-mesa-dev
or
libgl1-mesa-dev
libglu1-mesa-dev
because your Ubuntu lack of the files.

Thanks a lot... after installing libgl1-mesa-dev and libglu1 problem solved...

Do you recommend any other things to install to my system not to have this king of problems?

@zeroptr
Not to worry, because of the different systems, we will be missing a different file, when encountering problems, first step search internet, if no solution is found, and then ask.
