/usr/bin/ld: 找不到 -lGL (Ubuntu 14.04)

Question

I'm trying to build a project created in QT Creator and unfortunately every time I try to compile I get an error. Here is my compiler output:

23:02:20: Running steps for project WallpaperAppQt...
23:02:20: Configuration unchanged, skipping qmake step.

Answer 1

You need a package that provides the libGL.so (no version suffix) symlink. In Ubuntu, it's in the libgl1-mesa-dev package. So just do:

sudo apt install libgl1-mesa-dev

Answer 2

I was able to fix my problem by following the instructions in this link:

http://techtidings.blogspot.com/2012/01/problem-with-libglso-on-64-bit-ubuntu.html

(the final two commands)

sudo rm /usr/lib/x86_64-linux-gnu/libGL.so 
sudo ln -s /usr/lib/libGL.so.1 /usr/lib/x86_64-linux-gnu/libGL.so 

Answer 3

It's obvious that ld doesn't find lib GL in default library path which should be include /lib* /usr/lib* . You should install library GL or tell g++ where lib GL was installed with cmd args -L if that was installed already.

Answer 4

I am having the same problem. then I use in terminal "sudo apt install mesa-common-dev libglu1-mesa-dev" and the application run perfectly.
