Installation and Deployment

I'm trying to find specific conditions where the qmutex library crashed on note 4 without going to another device. Sorry my english is not good when using the word "compatible" in this case.

Which was just making sure the qml was scanned with macdeployqt's -qmldir flag.

Group, At least one way of solving the problem for Qt 5.8 and a ubuntu 16.04 derivative target is by the following commands: i) sudo apt-get install gstreamer1.0-plugins ii) sudo apt-get install gstreamer1.0-libav Hoyt

thx all for answer.

Hi, IIRC, Qt 5.9.1 supports 10.10 as minimal version, you might be hitting something related to that.

Is there a difference between Quick Controls and Quick Controls 2 Yes, QQ 1 was the first iteration, QQ 2 is the new one. They are not the same, QQ 2 was redesigned and implemented from scratch due to certain problems in QQ 1. are both included in the initial installation Yes.

Hi and welcome to devnet, What Linux distribution are you using ? What graphic hardware to you have ? What drivers for that hardware do you use ?

Then I wonder if it's a video driver problem...

Hi! Google gave me this https://bugreports.qt.io/browse/QTIFW-166 and this http://blog.qt.io/blog/2015/04/07/qt-installer-framework-2-0-released/#comment-1195532 for headless install.

I will reply to my own question. I do apologize to everyone for being thick/new here. The problem was with corrupted Visual Studio installation. After re-install, all was corrected, without reinstall of QT Creator.( Hats down to you guys). My next task to setup Android compiler. Back to Google. Thank you, to everyone, who looked into this.

@Wieland cross compile sounds good but certain ROS packages that I plan to run on the nanopi M3 have Qt5 as dependency. So I think Qt5 has to be installed and setup on the nanopi as well. What do you think ?

Hi and welcome to devnet, Do you have the application still running ? If so you should first stop it. IIRC, recent version of Qt Creator do that for you, or at least there's a setting for that. If not, got any antivirus running on your system ? Some of them tent to put the generated executable directly in quarantine.

Please don't highjack other people thread. You are already getting answers on your other thread here. And you should use the complete path to the qmake of the version of Qt you are trying to build the plugin for. Without the path, you are calling your distribution installed qmake. Furthermore this one is for Qt 4.

Hi, Did you try to start your application with the "QT_DEBUG_PLUGINS" environment variable set to 1 ? That might give you more information about what is happening with your plugin.

@SGaist thanks i will check with them.

Hi and welcome to devnet, Do you have an example of such tests ?

Can you check what differs between the two implementation ?

Ok thanks, I thought I read somewhere that qmake was a part of QtCreator, not Qt itself.
