    Default QT c++ OPENGL

    Greetings,
    I would like to know how to make an application made with opengl be seen on other machines that do not have QT installed, I copied the plugins
    • Platforms
      • qwindows.dll


    And the dlls
    • libEGL.dll
    • libgcc_s_dw2-1.dll
    • libGLESV2.dll
    • libstdc++-6.dll
    • opengl32sw.dll
    • Qt5Core.dll
    • Qt5Gui.dll
    • Qt5OpenGL.dll
    • Qt5Widgets.dll


    Int the program root but it still does not work. The application runs, but when creating the part of the “animation” the program is broken and sometimes I only get the widget in total black, help me please.

    It is possible that the level of GL support on the deployment PC is not as high as that on your development machine. It isn't a Qt problem, most likely. If you didn't have the right set of Qt DLLs deployed, the program would not run at all. See if you can find an OpenGL diagnostic tool you can run on both PCs. There is a list of tools here.

    If I install QT it works fine. The problem is which dll is specific to OPENGL???, because windeployqt already executed it and already copied the other dlls and plugins.

    You could try the good old Windows Dependency Walker tool (depends.exe) to look at either your executable or Qt5OpenGL.dll to see if that tells you anything about which GL dlls it is pulling in.
