Error while building Qt from source code on macOS



  • Hello,

    I want to be able to debug into qt source code so i started compiling the latest Qt version 5.8 on my MAC.
    I followed the instructions on Qt webpage about building it. But this is what i get after running configure.

    **../qt-everywhere-opensource-src-5.8.0/configure -prefix /Users/userName/qt-install-5.8 0 -opensource -debug-and-release
    + cd qtbase
    + /Users/userName/qt-everywhere-opensource-src-5.8.0/qtbase/configure -top-level -prefix /Users/username/qt-install-5.8 0 -opensource -debug-and-release

    Preparing build tree...
    Creating qmake...
    ............................................................................................Done.
    
    ERROR: Invalid command line parameter '0'.**
    

    I don't understand the last line. I was trying to do a shadow build by creating a new folder for build. I also specified the install directory while running config above. After running config, these are the files that got created in my build folder.

    config.cache config.log qtbase

    Does this look correct.?

    I am a newbie to MAC platform but i've completed compiling QT from sources on windows & linux.

    When i run make, this is what i got

    make
    make: *** No targets specified and no makefile found.  Stop
    

    Thanks in advance for your help.

    Hi,

    You prefix parameter is wrong. It's missing a point between 8 and 0.



  • Thank you @SGaist.
    Sorry for this stupid mistake.

    I'll try with this and compile QT on mac.
    Thanks again
