    If needed earlier, macdeployqt can be manually built from the dev branch.

    Hi @fortress,

    your conclusion is good, however neiter MSVC 2015 nor GCC 5.3 are full C++17 capable. So some C++17 features might work, others will not.

    I think I can try to create a simple project that will use <thread> and check how it will be compiled.

    Probably a good idea :)

    Hi,

    From the QtGStreamer wiki:

    The QtGStreamer C++ bindings are very out of date and unmaintained.

    For integration with the Qt toolkit there is the qmlglsink element in gst-plugins-bad (soon to be moved to gst->plugins-base or -good) which is a video sink that renders to a QQuickItem in a QML application.

    @SGaist
    @TobbY

    mank thanks to you both;

    finally, i solved this problem. in fact it's very easy.
    @TobbY is absolutely right.
    just put the dependencies dlls(here the only one Qt5Core.dll) and my dll in the same dir.
    i code the absolute path in the mql5,but left the dependency dll on the mt5's library before. that's not right.
    i'm so stupid! so i should give trust on the qt. it's my fault

    Yes, that was exactly one of the intentions when the sub-forum was proposed to be listed.
