QMAKE DEFINES in Application



  • Hello, Everyone

    I`m try use QMAKE DEFINES in cpp source.
    I put this values into my .pro file

    VERSION = 1.0.1.2
    DEFINES += VERSION=\\\"$$VERSION\\\"
    

    And read in cpp source

    QString version(VERSION);
    qDebug() << "Version" << version;
    

    But when I compile with MSVC 2013 I have this error

    ****\main.cpp:8: error: C2065: 'VERSION' : undeclared identifier
    

    How I can read DEFINE from *.pro file?



  • Hi! MSVC and gcc use different syntax for constants on the command line. The following should work (can't test it right now):

    VERSION = 1.0.1.2
    unix:DEFINES += VERSION=\\\"$$VERSION\\\"
    win32:DEFINES += VERSION=\"$$VERSION\"
    

    EDIT: There have to be DOUBLE DOLLAR SIGNS. The forum software won't let me type this correctly. :-/



  • Ok,
    I test it. And...... It isnt work

    I`m change

    VERSION = 1.0.1.2
    DEFINES += VERSION=\\\"$$VERSION\\\"
    

    to

    unix:DEFINES += VERSION=\\\"$$VERSION\\\"
    win32:DEFINES += VERSION=\"$$VERSION\"
    

    And I have error:

    ****\main.cpp:8: error: C2065: 'VERSION' : undeclared identifier
    


  • Really? Just to be sure: Please clean your project and rebuild it.



  • Clean project
    And have new error

    ****\main.cpp:8: error: C2143: syntax error : missing ')' before 'constant'
    ****\main.cpp:8: error: C2664: 'QString::QString(QStringDataPtr)' : cannot convert argument 1 from 'double' to 'const QChar *'
    ****\main.cpp:8: error: C2059: syntax error : ')'
    

    EDIT:
    Now I add new macro

    #define _TOSTR(x) #x
    #define TOSTR(X) _TOSTR(X)
    

    And now I can use DEFINES from *.pro file
