[SOLVED] Building Qt Creator fails

  • Qt Version: 5.3.1
    OS: CentOS 6.4
    Qt Creator Version: 3.1

    Downloaded from git and attempted to install using these commands:

    @git clone --recursive https://git.gitorious.org/qt-creator/qt-creator.git
    mkdir qt-creator-build
    cd qt-creator-build
    export QTDIR=/Qt/5.3.1_shared
    export PATH=$QTDIR/bin:$PATH
    which qmake

    qmake -v
    QMake version 3.0
    Using Qt version 5.3.1 in /Qt/5.3.1_shared/lib

    qmake -r ../qt-creator/qtcreater.pro
    ... Lots of stuff scrolls by and then:
    Project ERROR: Unknown module(s) in QT: quick@

    How do I get past this?

    Qt was also downloaded and installed from git. Here is the configure call I used:
    ./configure -prefix "/Qt/5.3.1_shared -shared -spec linux-g++-64 -opensource -confirm-license -I/usr/include/mysql -L/usr/lib64/mysql -qt-sql-mysql


  • With assistance from the support group at Digia, I was able to solve this issue. For the sake of posterity, here is the procedure I followed to successfully install Qt 5.3.1 and Qt Creator 3.2.1 on CentOS 6.4 64-bit with MySQL support:

    Please note: This entire process can take a couple of days to complete:

    @1. Install CentOS 6.4 Basic Server + mysql and web server support.
    2. yum update@
    There will be hundreds of updates so this may take a several minutes (15 to 20 minutes).
    Last time I did this, it installed 382 updates.
    3. Install dependences for Qt:
    as root:

    @yum install libxcb libxcb-devel xcb-util xcb-util-devel
    yum install flex bison gperf libicu-devel libxslt-devel ruby
    yum install git
    yum install gcc-c++
    yum install mysql-devel
    yum install libX11-devel
    yum install libXrender-devel
    yum install libusb-devel
    yum install mesa-libGL-devel@

    1. Install devtools
      @wget http://people.centos.org/tru/devtools-1.1/devtools-1.1.repo -P /etc/yum.repos.d
      sh -c 'echo "enabled=1" >> /etc/yum.repos.d/devtools-1.1.repo'
      yum install devtoolset-1.1@

    2. Download latest Qt from Git:

    @git clone git://gitorious.org/qt/qt5.git qt5
    cd qt5
    git checkout stable
    perl init-repository@
    This will take 30 to 45 minutes.

    1. Set the environment

    By default, CentOS will set the following environmental variables:

    These must be unset before proceeding.

    @env | grep QT@

    @unset QTDIR
    unset QTINC
    unset QT_IM_MODULE
    unset QTLIB
    env | grep QT@

    Now set the environment to use dev tools

    @scl enable devtoolset-1.1 bash@

    1. Configure, build, and install shared version of Qt

    @cd qt5
    ./configure -prefix /Qt/5.3.1_shared -shared -platform linux-g++-64 -opensource -confirm-license -debug-and-release -I/usr/include/mysql -L/usr/lib64/mysql -qt-sql-mysql @
    Takes 15 - 30 minutes.
    If installing on a multi-core virtual machine, type make -j# where # is the number of cores.
    Takes 4 to 8 hours. Sometimes best to let it run over night.

    As root from $HOME/qt5:
    @make install@
    Takes 20 minutes to an hour.
    @make install docs@
    Takes 20 minutes to an hour.

    1. Download QtCreator from git

    From $HOME as development user:

    @git clone --recursive https://git.gitorious.org/qt-creator/qt-creator.git@

    1. Create build directory for qtcreator

    @mkdir qt-creator-build
    cd qt-creator-build@

    10 Set the environment:
    @scl enable devtoolset-1.1 bash
    export QTDIR=/Qt/5.3.1_shared
    export PATH=$QTDIR/bin:$PATH
    which qmake@

    1. Build Qt Creator
      @qmake -v@
      QMake version 3.0
      Using Qt version 5.3.1 in /Qt/5.3.1_shared/lib

    @qmake -r ../qt-creator/qtcreator.pro

    Takes 5 to 9 hours. Maybe another all nighter.
