Project ERROR: Cannot run compiler 'g++'. Maybe you forgot to setup the environment?



  • I`m trying to build mysql drives like it is said Here.

    so i ran these comand:

    qmake "INCLUDEPATH+=-/usr/include/mysql" "LIBS+=-L/usr/lib/x86_64-linux-gnu -lmysqlclient" /home/chawila/Downloads/qt-everywhere-opensource-src-5.9.1/qtbase/config.tests/unix/mysql/mysql.pro
    

    Then i got these error:

    system(execute) requires one or two arguments.
    Project ERROR: Cannot run compiler 'g++'. Maybe you forgot to setup the environment?
    

    what can i do?.
    i have two weeks trying these, posting on these forum but i cant get any help.

    Hi,

    It looks like you have gcc but not g++ installed.



  • @SGaist

    /usr/bin/g++
    

    i`m marking these solved because i found another away of building mysql drivers here
