Qt Build Problem on Mac (g++-4.2: No such file or directory)



  • Hello Qt-Community,

    I'm very new in developing in qt. So i have written a desktop application but after i updated Xcode the code don't get build.

    If i want to compile its keeps on writing: g++-4.2: No such file or directory

    I have read here in the forum about solving this problem but couldn't fix it.

    So my qmake command looks like this:
    qmake /Users/alikara/Dropbox/Seminararbeit/CZE-Projekt/CZE-Projekt.pro -r CONFIG+=release -spec macx-gcc

    It means i added -spec macx-gcc ass a additional argument but it doesn't helped.

    So i tried to change the toolchain to clang but it doesn't helped too.

    So i tried to symlink g++/gcc to g++-4.2/gcc-4.2 but don't found gcc-4.2 in /usr/bin/

    My /usr/bin/ looks like this:
    lrwxr-xr-x 1 root wheel 12 25 Jan 08:00 g++ -> llvm-g++-4.2
    -r-xr-xr-x 1 root wheel 101670 3 Nov 22:56 gatherheaderdoc
    lrwxr-xr-x 1 root wheel 12 25 Jan 08:00 gcc -> llvm-gcc-4.2
    lrwxr-xr-x 1 root admin 32 25 Jan 08:00 llvm-cpp-4.2 -> ../llvm-gcc-4.2/bin/llvm-cpp-4.2
    lrwxr-xr-x 1 root admin 32 25 Jan 08:00 llvm-g++ -> ../llvm-gcc-4.2/bin/llvm-g++-4.2
    lrwxr-xr-x 1 root admin 32 25 Jan 08:00 llvm-g++-4.2 -> ../llvm-gcc-4.2/bin/llvm-g++-4.2
    lrwxr-xr-x 1 root admin 32 25 Jan 08:00 llvm-gcc -> ../llvm-gcc-4.2/bin/llvm-gcc-4.2
    lrwxr-xr-x 1 root admin 32 25 Jan 08:00 llvm-gcc-4.2 -> ../llvm-gcc-4.2/bin/llvm-gcc-4.2

    So please can someone help out?

    Did you rerun qmake after making those changes?

    Please try the Qt Creator 2.4.1 release from today. It should fix the issue.
