  • I have a simple program for testing the istallation of Creator, but when i compile the program,
    lauch this message and can't run. i work on xubuntu

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

    on screen compile output:

    15:10:14: Running steps for project test3...
    15:10:14: Configuration unchanged, skipping qmake step.
    15:10:14: Starting: "/usr/bin/make"

    Error while building/deploying project test3 (kit: Kit_lucho)
    When executing step 'Make'
    15:10:15: Elapsed time: 00:00.

    And this message is the first intent to compile, whit another kit (default) (the same simple program):

    15:45:03: Running steps for project test2...
    15:45:03: Configuration unchanged, skipping qmake step.

    You are missing the opengl dev files



  • Hello SGaist:
    Can you tell me how to install thats files and first where find it.
    I work on Xubuntu

    Did you try to search this forum a bit ?
    This question as already come up several times on the forum (xubuntu is just a derivative of ubuntu)

    Anyway have a look "here":http://qt-project.org/wiki/Building_Qt_5_from_Git even if you don't build Qt yourself the information is valid



  • Thanks a lot SGaist; I couid solve the problem.
