libgbm.so.2 => not found



  • Hi,

    When i run my fresh built qt5.7 applications, it says libgbm.so.2 is missing.
    I run ldd agains libEGL.so.1, and found libgmb.so.2 is not found.
    the system has only libgbm.so.1, and I searched on google failed to find libgbm2.
    please advise how to proceed.

    @wweiradio Try creating a symbolic link to libgbm.so.1.



  • i tried, it did not work.



  • I take a further look, I think the method works.
    It turned out i have another problem. Seems that I need to change the compiler and recompile.

    /usr/local/qt5/lib/libQt5Gui.so: undefined reference to operator delete(void*, unsigned int)@CXXABI_1.3.9' /usr/local/qt5/lib/libQt5Gui.so: undefined reference tooperator delete[](void*, unsigned int)@CXXABI_1.3.9'
