    I mean that if the library was compiled with MinGW, you might have unexpected dependencies. That's how you get the error he reported. Dependencies are missing.

    Ok, I solved the problem. The problem was, that in the common.h file there were function definitions, so i separated it to .cpp and .h file.
    Thanks all.

    @krekeltronics I don't actually have a Windows machine in the house; what little Qt-on-Windows I have done (mainly for the purposes of trying out AppStream, which is Windows) has actually been entirely on an AWS EC2 Windows instance. Works fine. Think the real question isn't whether you should think about which of these cloud services you should use, but which one (MS Azure or Google Compute Cloud being the obvious other choices).

    Do a small search on the forum, there was already a thread about Qt-VLC last week that might help you.

    Now it's distributed as package of MSYS2 project.
    Type in the appropriate shell:

    pacman -S mingw-w64-i686-osgQtQuick

    or

    pacman -S mingw-w64-x86_64-osgQtQuick

    To run test game script:

    wget https://github.com/podsvirov/osgqtquick/raw/develop/tests/sokoban.qml qmlscene sokoban.qml

    Hi and welcome to devnet,

    You don't link to dlls but to lib files but you don't use the file extension.

    So essentially:

    LIBS += -lgsl -lgslcblas

    Hi and welcome to devnet,

    Why the double conversion to stdString and c_str ? You can use something like toLatin1 if you want a QByteArray to write to your serial port.

    Hi,

    The answer might look silly but do it the same way you would develop a class MSSCCI but use Qt's internally.

    It is a very old post, but maybe you would be interested in knowing that there is such component for Qt under commercial license - QtitanFastInfoset -http://www.devmachines.com/qtitanfastinfoset-overview.html

    Just added an entry in cmake-gui with path to folder.

    Thanks SGaist!

    @SGaist
    Hi! yes I have checked this before but I dropped it, I got many errors because I don't know how to link the libraries in the command prompt

    'nmake -f makefile.vc TARGET=rel'

    And the link does not contain Qt5 . When I downloaded the latest release of poppler, it didn't come with makefile.vc file. So I decided to go with CMake GUI.

    I'm not comfortable with makefiles, I prefer to use CMake GUI (easy to include lib & dir) since I already built zlib, freetype and libjpeg libraries in vs2013 win64

    Regards,

    Hi and welcome to devnet,

    Nope, you're on the wrong forum. PyQt is developed by Riverbank here

    Note that that value reminds me of QWIDGETSIZE_MAX

    Hi and welcome to devnet,

    The first thing to do is verify that the compiler used to build OpenCV matches the one used for Qt.

    As for using OpenCV and Qt together, please search this forum, it's a question that has been asked and answered many times already.

    hmm, not sure about that one... I think I did, but I know I've been putting this laptop into suspend often because it's not the fastest pc I have :-)

    Anyway, I found this on https://help.ubuntu.com/community/EnvironmentVariables

    Shell config files such as ~/.bashrc, ~/.bash_profile, and ~/.bash_login are often suggested for setting environment variables. While this may work on Bash shells for programs started from the shell, variables set in those files are not available by default to programs started from the graphical environment in a desktop session

    So I didn't test any further.

  • Using Gradle to build Qt C++ app

    I have the same issue.
    Gradle 2.5 supports continuous building and I decided to switch the build from qmake to Gradle(Qbs doesn't support continuous builds).
    There doesn't seem to be any plugin.
    I see only 2 solutions:

    Have a gradle task that runs qmake on project files and mention the moc files in there as sources but you will not have the advantage of proper caching and dependency management, probably error prone in some edge cases. Implement a gradle plugin that simulates the tasks qmake does - especially for a person that doesn't develop qmake, this would be very cumbersome to do right. Some colleagues of mine did this for a Windows build system, if I remember correctly it took them ~1-2 months...
    They were not familiar with Qt and qmake when they started but at the same time, they are paid to do this all day.
