Installation and Deployment

It should point to your application QML sources.

I should have also mentioned, for completeness: I 100% agree with @jsulm 's hypothesis that "The IDE is most probably not the problem here" However, the set of possibilities that contains the actual problem could still be a very large set (possibly unbounded?). Therefore, if you are under a deadline for coursework, that is why I recommend just sticking verbatim to whatever the instructor is doing.

@Chiquito said in Install visio studio to QT creator: i have problem to add visio studio to QT creator Do you mean you want to use Microsoft C++ compiler in QtCreator? "but i can not install it" - what exactly? Visual Studio? You need to install Visual Studio or Microsoft Build Tools and then Qt for MSVC++ compiler.

Found the solution, install qtdeclarative5-dev package; Type in terminal; sudo apt-get install qtdeclarative5-dev

@Chiquito https://forum.qt.io/topic/129236/how-to-create-exe-with-qt-creator?

Yes, using newest available driver from Nvidia 470.

ended up having to walk through dependency walker to solve as some necessary dll files were not where they needed to be.

@Christian-Ehrlicher Thanks so much for your help, I think I solved the problem. Inside the QT directory, there is plugins directory. And inside it there is tls directory which contains 3 dlls: certonlybackend.dll, opensslbackend.dll and schannelbackend.dll. I copied this tls directory next to .exe, I can deploy with OpenSSL now.

@Samuel-Alves Hi and welcome to devnet, You have to give the path to your qml sources. The ones that you have in your sources not the one from Qt.

Then install them...

Hi, Dependency Walker won't help you there because OpenSSL is not linked in the pre-built binaries. You can get OpenSSL using the installer/maintenance tool. Check the dependencies of your libraries to see if you are not missing a runtime library.

Just to build on @SGaist 's remarks, some info regarding what Qt has named mkspecs: https://doc.qt.io/qt-5/configure-options.html#compiler-options

If using Ubuntu 16.04 is somehow a requirement, then I can attest that I was able to compile Qt 5.14 from source on Ubuntu 16.04. Here is the build script I used. You should probably apt install most of what is listed here in this other preparatory script of mine. I also see that I wrote this note to myself, but my memory fails me as to exactly why this was needed: # if you are on Ubuntu 16.04 you probably need to also run: # sudo add-apt-repository ppa:ubuntu-toolchain-r/test # sudo apt-get update # sudo apt-get install gcc-7 g++-7 # sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-7 60 # sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 60

Hi @Robber, and welcome! Which file is failing the hash verification? If it is not an important one, try deselecting it before you start the installation. (A few weeks ago, Debugging Tools for Windows was failing hash verification, but you can install Qt without it)

There might be something else missing. Start Qt Creator with the QT_DEBUG_PLUGINS environment variable set to 1 to get more information about what is going on.

Hi, AFAIR, you do not need to use a special terminal, just use the full path to the windeployqt executable you want to use.

Hi, This means that you did not deploy the image format plugins correctly or not completely.

First try to for the use of OpenGL. Otherwise, you will have to build Qt itself.

My packages for gstreamer: sudo apt-get install --reinstall libxcb-xinerama0 sudo apt-get install -y libqt5gstreamerquick-1.0-0 sudo apt-get install -y libcairo2-dev sudo apt-get install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio sudo apt-get install libgstreamer-plugins-base1.0-d sudo apt-get install libqt5gstreamer-dev sudo apt-get install libgstreamer1.0-dev sudo apt-get install libgstreamer-plugins-base1.0-d sudo apt-get install libgstreamermm-1.0-dev sudo apt-get install qtdeclarative5-dev And i could see packages in both path which are; "/usr/lib/x86_64-linux-gnu/" and "/usr/lib/x86_64-linux-gnu/pkgconfig/" After these installations i can run my program if i install from terminal with commands: sudo apt install build-essential sudo apt install qtcreator sudo apt install qt5-default But i can't run program if i install from offline source. Really i can't understand the difference.
