Hi all,

I'm trying to compile my QtGui project with ubuntu , (the project source has been created ago with windows OS ago ) i would like compile the same code with qt in ubuntu . but many many errors related of the QopenGl has been got .

however , i created a new project and compiled succesflly for checking if the some errors wil disply again .

i use the same qt version with the both OS . don't think if the issues geted case a versionning problem .

any help .

Hi
Did you install the openGl dev libs ?

https://wiki.qt.io/Install_Qt_5_on_Ubuntu

Install OpenGL libraries
Execute the following command to install OpenGL libraries:

sudo apt-get install mesa-common-dev
also maybe
sudo apt-get install libglu1-mesa-dev -y

@Maarouf-Med-Mahdi After installing mesa stuff - did you run qmake and rebuild your project?

Maarouf Med Mahdi · 4 Dec 2018, 10:09

Hi @jsulm
Yes , clean , run Qmake and rebuild all . nothing new :(

SGaist · 12 Apr 2018, 23:20

Did you check with a more recent version of Qt ?

On Linux, i'm doing the following:

sudo apt-get install build-essential
sudo apt-get install libgl-dev libglu-dev

Work well with Ubuntu, Cinnamon and others.

just i want to say same thing .
i tested a new empty project has compiled correctly , but my last project can not be done .

jsulm · 13 Apr 2018, 15:22

@Maarouf-Med-Mahdi Delete the build folder of your project and do a clean rebuild.
Also, are you doing anything special in this (not working) project?

Maarouf Med Mahdi · J jsulm 13 Apr 2018, 05:25

Hi @jsulm
just i created the project on windows OS , and the same project i try to compile it on ubuntu .
my objective is to deploy my app with Linux OS .

SGaist · 14 Apr 2018, 03:07

Is it a newly created default project ?

Maarouf Med Mahdi · S SGaist 13 Apr 2018, 19:39

Looks like there's something fishy with your kit then.
