You should install package «libgl1-mesa-dev»:

sudo apt install libgl1-mesa-dev

you don’t need to install anything. libGL is already installed with Ubuntu, you just need to soft link it. (tested for ubuntu 14.x and 15.x, might work for later versions)

  1. First locate the GL library
  2. Then link it under /usr/lib
  3. If the library is missing, it can be installed via libgl1-mesa-dev package

Here is how you could do this:

$ locate libGL
/usr/lib/i386-linux-gnu/mesa/libGL.so.1
/usr/lib/i386-linux-gnu/mesa/libGL.so.1.2.0
/usr/lib/x86_64-linux-gnu/libGLEW.so.1.10
/usr/lib/x86_64-linux-gnu/libGLEW.so.1.10.0
/usr/lib/x86_64-linux-gnu/libGLEWmx.so.1.10
/usr/lib/x86_64-linux-gnu/libGLEWmx.so.1.10.0
/usr/lib/x86_64-linux-gnu/libGLU.so.1
/usr/lib/x86_64-linux-gnu/libGLU.so.1.3.1
/usr/lib/x86_64-linux-gnu/mesa/libGL.so.1
/usr/lib/x86_64-linux-gnu/mesa/libGL.so.1.2.0
/usr/lib/x86_64-linux-gnu/mesa-egl/libGLESv2.so.2
/usr/lib/x86_64-linux-gnu/mesa-egl/libGLESv2.so.2.0.0
$ sudo ln -s /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1 /usr/lib/libGL.so

The gui Qt module is included by default. If you don’t want to use it in a project (e.g., it is a library or only uses stdio), you need to specify that in the .pro file.

QT -= gui

And the linker won’t attempt to find lGL regardless of whether it is installed.

My case is admittedly a bit odd, since the main reason to use Qt is to create gui’s. Installing the GL library is certainly not difficult, I just wanted to know why my quick and dirty Hello World wanted it.

This worked for me:

sudo ln -s /usr/lib/libEGL1.so /usr/lib/libGL.so

My system is Ubuntu 16.04 on x86 computer(with NVIDIA GeForce GPU).

Check the library files located in /usr/lib/x86_64-linux-gnu

ls -al /usr/lib/x86_64-linux-gnu/libG*

If you see the broken link, reinstall libgl1-mesa-glx

sudo apt install --reinstall libgl1-mesa-glx

And, recheck library.

Solved this problem just a minute ago in suse.
Just do the following step below and QTCreator should works just fine.

sudo zypper install —type pattern devel_basis

Скорее всего у вас отсутствует пакет разработчика для библиотеки OpenGL. Установите пакет mesa-common-dev.

sudo apt-get install mesa-common-dev
sudo apt-get install freeglut3-dev

P. S. Такой совет пригодится для любой библиотеки, когда что-то не линкуется.

скорее всего, Qt не может найти библиотеку OpenGL (не знаю, зачем она ему для компиляции свежесозданного девственно чистого проекта в моем случае)
для начала можно посмотреть, на что ссылается симлинк:
ls -l /usr/lib/libGL.so*

  1. удалить существующий /usr/lib/libGL.so
    sudo rm /usr/lib/libGL.so
  2. выполнить в командной строке
    locate libGL.so
  3. принудительно прилинковать любой из найденных файлов в формате
    sudo ln -s -f /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1
 /usr/lib/libGL.so

P.S.: совет может оказаться не таким уж и хорошим, но мне в решении аналогичной проблемы помогла именно эта последовательность действий

Cause: QT cannot find the dynamic link library of OpenGL. QT usually looks for dynamic link libraries in/usr/lib directory, but some Linux distributions will place OpenGL dynamic link libraries in other directories. For example, Ubuntu will be placed in/usr/lib/i386 Linux GNU/Mesa/. There are two solutions:

Method 1: directly copy the OpenGL dynamic link library file in/usr/lib/i386 Linux GNU/Mesa/directory to/usr/lib.

Note: the built-in OpenGL library in Linux will have the version number at the end, such as LIBGL.So.1, LIBGL.So.1.2. However, the file required by QT when linking does not have a version number, that is, libgl.so. Method 2: create a soft link for the OpenGL dynamic link library file in/usr/lib/i386 Linux GNU/Mesa/directory

ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/libGL.so

  • i have downloaded qt libraries from http://qt-project.org/downloads > Qt libraries 5.0 RC 2 for Linux 64-bit (382 MB) and installed them.
    when i try to build a Qt Gui Application project with auto-generated files mainwindow.h, mainwindow.cpp and main.cpp i get these messages «cannot find -lGL» and «collect2: ld returned 1 exit status». how to fix it?
    ubuntu 12.04

  • Just install libGL incl. the dev-packages for it.

  • how to do that?

  • Which distribution do you use?

    Wich Graphicsdriver? See my post in 3th party for ati readeon graphiccards.

  • ubuntu 12.04
    nvidia

  • nvidia proprimentar? or «normal»

    open Software-center and search for OpenGL -> install allso -dev packs.

  • how do i find out what kind of driver i have?

  • Did you installed the default driver or have you installed explicit the Nvidia?

  • default

  • what should i install in software center?

  • Solved the problem by installing the “libglu1-mesa-dev” package.
    @sudo apt-get install libglu1-mesa-dev -y@

  • Thanks for the reply.

    I have ran these commands

    @yum install mesa-libGL-devel mesa-libGLU-devel
    yum install qt
    yum install qt-creator@

    and then installed Qt 5.4.1 for Android (Linux 64-bit, 616 MB)

    I am on centos 7 x64 but it still does not work
