Error compiling project in QT Creator

Question

I am seriously wanting to study programming and I chose the QT framework when I was with a dualboot on my computer there was this problem that I am having now after removing the dualboot and install only Ubuntu 14.10.

In Ubuntu installed QT without problem and when compiling the project QT Creator is giving me the error below. How to solve this problem?

Answer 1

Logico this and the problem friend, you know more with a little search I managed to solve only was to type in the terminal sudo sudo apt-get install libqt4-dev and the problem will be solved

Answer 2

Your mistake basically is this:

/usr/bin/ld: cannot find -lGL

At this link, I found the following tip:

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

Another tip I found on this other link. Take a look at the folder /usr/lib and see if the libGL.so is there. If you are, but with a different name, you can do this:

sudo ln -s /usr/lib/libGL.so.xx.xx.xx /usr/lib/libGL.so

In a question on Stackoverflow in English, someone had the same problem that you and managed to solve. In his case, the libraries were in the folder /usr/lib/nvidia-current, then to resolve, the accepted answer from there suggests something more or less like this:

sudo ln -s /usr/lib/nvidia-current/libGL.so.1 /usr/lib/libGL.so.1
sudo ln -s /usr/lib32/nvidia-current/libGL.so.1 /usr/lib/libGL.so.1
sudo ln -s /usr/lib/nvidia-current/libGL.so /usr/lib/libGL.so
sudo ln -s /usr/lib32/nvidia-current/libGL.so /usr/lib/libGL.so

Maybe this will solve.
