[Solved] My first solution with QMAKE


  • Hi,

    I have just registred to the forum after some months just reading your interesting posts.
    I'l try to explain you what problem do I have and let's see...

    I usually work in Windows using QT (and Visual Studio) but at home I have a mac (MacBook Pro with Snow Leopard 10.6.8) and I want to be able to work with it too.
    I want to use QT and CMake to create the solution of the project we are working. In my Mac I have installed Xcode, the full QT application framework and CMake. I'm trying to create the solution via QT and CMake trougth a CMakeLists.txt.

    When I try to configure and generate the solutuion, I get this:

    @
    CMake Error at /Applications/CMake 2.8-8.app/Contents/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:97 (MESSAGE):
    Could NOT find Qt4 (missing: QT_QMAKE_EXECUTABLE QT_MOC_EXECUTABLE
    QT_RCC_EXECUTABLE QT_UIC_EXECUTABLE QT_INCLUDE_DIR QT_LIBRARY_DIR
    QT_QTCORE_LIBRARY)
    Call Stack (most recent call first):
    /Applications/CMake 2.8-8.app/Contents/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:288 (_FPHSA_FAILURE_MESSAGE)
    /Applications/CMake 2.8-8.app/Contents/share/cmake-2.8/Modules/FindQt4.cmake:1172 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
    commonLib/CMakeLists.txt:17 (find_package)
    @

    QT is not able to find QT_QMAKE_EXECUTABLE, QT_MOC_EXECUTABLE, QT_RCC_EXECUTABLE, QT_UIC_EXECUTABLE, QT_INCLUDE_DIR, QT_LIBRARY_DIR and QT_QTCORE_LIBRARY.

    I read that to solve this I have to configure the Environment Variables of my system but in all the posts I read they add to $HOME/.profile:

    @
    PATH=/usr/local/Trolltech/Qt-4.7/bin:$PATH
    export PATH
    @

    In my Mac the folder /usr/local/Trolltech doesn't exist so I have no idea what I have to do. What should the content of that folder be? I have installed the last and full QT package so I don't understand why I don't have that directory. I have installed the SDK in $HOME/QtSDK (by default it is installed there).

    Anybody know how can I solve it to be able to run cmake and generate the solution for QT?

    Thanks in advance.

    CMake needs the "qmake" exectuable to figure out where the Qt installation is.

    Being able to find that file is what "PATH=/INSTALL/DIR/bin:$PATH; export PATH" is all about: It makes sure the qmake of the Qt version installed in "/INSTALL/DIR" (replace with whatever matches your system) is found.

  • First of all thanks for your fast answer.

    By Install Dir you mean Qt creator directory? qmake directory?
    I found diferent qmake executables in my system in:

    $HOME/QtSDK/Desktop/Qt/474/gcc/bin
    $HOME/QtSDK/Madde/tools/qt-tools_snow-leopard_2011-10-07_UnivBin_qt4.7.4-m0.22.12/bin
    $HOME/QtSDK/Simulator/Qt/gcc/bin
    $HOME/QtSDK/Madde/tools/qt-tools_snow-leopard_2011-10-07_UnivBin_qt4.7.4-m0.22.12/bin

    I have tried them and nothing.
    What I'm doing wrong?

  • More things... when I write:

    bq.
    echo $PATH

    I get this:

    bq.
    /Users/ricard/Applications/bin:/Users/ricard/Applications/sbin:/opt/subversion/bin/:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/X11R6/bin

    Nothing related with QT or CMake

    Which qmake to use depends entirely on which Qt you want to use.

    $HOME/QtSDK/Desktop/Qt/474/gcc/bin is a desktop Qt, Madde/... is for harmattan development, Simulator/... is the one if you want to use the Qt simulator.

  • Ok, thanks for your answers but the problem is still present. What I'm doing wrong? Maybe it is not Environment Variables fault, or maybe I have to put them in another place.

    In $HOME/.profile I have:

    bq.
    PATH=Users/ricard/QtSDK/Desktop/Qt/474/gcc/bin:$PATH
    export PATH

    But as I said, if I write:

    bq.
    echo $PATH

    I get this:

    bq.
    /Users/ricard/Applications/bin:/Users/ricard/Applications/sbin:/opt/subversion/bin/:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/X11R6/bin

    All this Environment Variables are not in the ".profile" that I'm editing to add the path to qmake, Where are them defined? Is there somwhere else where I can put the Environment Variables? Or anyway do you know how can I solve the problem I descrived in the first post?

    Thanks for your pacience.

  • No one had the same problem?

    After adding the Environment Vars I have restarted and everything, I'm thinking in reinstalling everything...

    I'm really lost, I don't understand why the QT installer doesn't add its own default Environment Variables on its right place automaticly.

  • Well, finally I nearly solved.

    I had to add the Environment Vars in ".bash_profile" and not in the ".profile". I have been looking for more information and I found this:

    bq. When a "login shell" starts up, it reads the file "/etc/profile" and then "$HOME/.bash_profile" or "$HOME/.bash_login" or "$HOME/.profile" (whichever one exists - it only reads one of these)

    I had the ".bash_profile" so the ".profile" was ignored, I didn't know that...

    I start the post saying that "I nearly solved" couse now I have other problems but I think they are not related with the same, let's see if I can mannage to get the solution.

    Thanks!
