"error: cannot find -lGL" after initial setup of Qt Creator on Linux

[graniteDev]

I just setup a kit for Qt Creator on Linux Mint. I've done this before in the past and had no issues, however today I'm getting these two errors trying to compile a test Qt Application that is in it's default state

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

Searching the internet didn't reveal anything specific to this error, and I've never seen it at work on Windows, so I'm not sure what this is or how to fix it.

It looks like I'm missing lGL

/usr/bin/ld: cannot find -lGL

How do I get this lGL?

The problem is the minus sign in -IGL
you should enclose it with commas like that:

cannot find "-lGL"

You can try:

sudo apt-get install libglu1-mesa-dev -y
Tested with Qt5.3.1 and Ubuntu 14.04 and it solved the problem with missing -lGL.

source: Install Qt 5 on Ubuntu

I didn't do that, that's copied right out of the error in the compiler window

You can try:

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

Tested with Qt5.3.1 and Ubuntu 14.04 and it solved the problem with missing -lGL.

I'm running Qt5.11.3, not sure if that's still compatible? Better question, will I brake anything installing this?

@graniteDev just do a google search, this is a common task. I've done it multiple times too, but I do google all the time again because I've forgot it.

No, it is a packet provided and tested by Ubuntu.

@mpergand Installing libglu1-mesa-dev fixed it. How did you know this? I searched for hours and nothing came up for the error's Qt was giving me. "lGL" really doesn't bring up anything in a search.

Hi,

@graniteDev because that's a question that has been asked a hundred times on this forum and others. If you search for cannot find lGL you'll have lots of answers both here and on your favorite search engine. However if you don't drop the -, search engines will specifically search for answer not containing what follows that sign.

Hi I now this thread is quite old but I'm having the same issue with a machine I'm working on in work, unfortunately this machine does not have any internet connection and everythiing we've tried to do to to get it connected to the network has failed. Therefore, we are unable to ran any of those commands to install the missing package 😢. Any suggestions for an offline solution ? any help would be greatly appreciated.

You can use a DVD or mount an image for your Linux distribution and use that as source for installation.
On Debian based distributions you will need to edit /etc/apt/sources.list file.
Fore more information refer to the documentation of your distribution.

Thanks for replying, I managed to get it using the following command.

[root@localhost ~]# ln -s /usr/lib64/libGL.so.1 /usr/ lib/libGL.so
