    The solution with the qt.conf works and I implemented a "svn-fit" solution that works for all users with a single touch at first co. All tools in /bin have hardcoded paths. I actually absolutely don't understand why one would design a system that creates executables with hardcoded paths in the firstplace ... but that's not the point here. @ [Paths] Prefix = /home/username/path/to/qt Examples = examples Demos = demos @

    The problem was solved - browsing the postings to the mailing list the last hours I found one with a link to this page: http://stackoverflow.com/questions/25940368/qt5-target-conditionals-not-found changing the qdevice.pri file to MacOS10.9 fixes the problems ( in the same step it eliminates problems with dylib image not found for all frameworks ) regards Steve

    Then you can follow the guide but call configure directly in qtbase, this way you will only have this module. Next step, build and install it. From thee, create a new subfolder for qtmultimedia go into it and call your installed qmake with /path/to/qtmultimedia/sources as parameter. Then make and sudo make install. Take the time to look at the configuration tests to see whether it finds everything it needs to build the module

    Particulary this problem was solved, thank you. We couldn't manage to work Qt 5.3 QML (QtQuick 2.0) on all hardware. But usual Widgets on problem hardware are working fine.

    Hi and welcome to devnet, Don't worry that's normal, it's the bootstrap part that creates the necessary files and tools that will be used to process the source tree to build Qt.

  • Install QtSerialPort to alternate location?

    Yes. I am trying to build QtSerialPort as part of a larger project that needs to use the serial port. This project should not be required to build all of Qt4 also, and installing QtSerialPort as root is not acceptable. I need to install QtSerialPort to a user writable directory. (Specifically, it should be installed to the prefix /project/root/build/install, where QtSerialPort itself is built in something like /project/root/projects/QtSerialPort/build.) It might be possible to use it without installing it, although that is not preferable and might cause other problems down the road (e.g. when we need to build installers for this project). For the moment I am just ignoring the qmake project files and have rolled my own build system for QtSerialPort using CMake, which natively supports an install prefix.
