Qt debian/ubuntu: Can't compile, error: cannot find -lGL

I have a problem building applications in Qt on Debian.

When I try to compile anything I get:

/usr/bin/ld: cannot find -lGL collect2: error: ld returned 1 exit status make: *** [test] Error 1 14:38:52: Proces "/usr/bin/make" zakończył się kodem wyjściowym 2.

Last line means: Procces(...) exited with code: 2

Any idea what's wrong?

Solution

Since this is a linker error, you may have one of two problems:

You don't have libGL installed
libGL is installed but not in your system path.

If libGL isn't installed, you can install it:

sudo apt-get install libgl1-mesa-dev

I think is the right package. I don't have a debian machine handy so I can't test it.

If you have this package installed, you need to add it to your system path. You'll need to append it to environment variable LD_LIBRARY_PATH or make a .conf file located in /etc/ld.so.conf.d/.

Again, I don't have a debian machine to verify these paths, but that's the best I can do from memory. Either way, this should be enough information to get started.

Good luck!
