      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

            Hi,

            Did you try to build your project with the Qt version provided by your distribution ?

                        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.

                                  @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?

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