Installation and Deployment

What I just found out: If I start/restart nmake module-qtwebengine several times (after the last build failed as stated above) the process fails always at a different point (concernint the list of read files). Has anyone got an idea what this means? Thank you, R.

@Shaoning-Di said in Qt Cmake configuration has no path to a C++ compiler set: but it didn't work What exactly did not work?

Thank you, jsulm! Although I was able to start downloading, after a few seconds the connection was dropped and now it gives 503 Service Temporarily Unavailable error on this site :( Attila

@codeNinja95 Sorry but with QT installer framework I never found as to install vc runtime. But if you use the last installer of Postgresql it installs vc runtime.

There is a Qt plugin for VS. This can import Qt projects and handle most of the stuff automatically. I personally prefer to use qmake.exe -tp vc MyProject.pro to generate a VS project file. If you want to be portable (Linux/macOS) I would say it is the preferred way to always make changes to the .pro file (adding/deleting files) and regenerate the VS project from it. I believe (I am not a great fan of the Qt plugin for VS and don't use it) that the Qt plugin does all the stuff necessary for the project file. But, it does not have the Qt Designer built in. You need to use Qt's own tools to still edit UI-files. If ICC does not show up inside Qt Creator automatically, you can add it by hand and then add it to a kit. I am not sure how well that is supported. Is there any specific reason you want to use ICC? A while back (I believe it was ICC v14) I did some benchmarks and ICC did not optimize OO code. It was slightly faster with regular C code, but no meaningful optimizations for C++. Only this year did they start to use clang as backend and I would expect that this version of the current ICC could actually be better. If you don't make sure to use the clang-variant of ICC and don't have any other specific reasons to use it (performance at least wasn't a reason a while back), just use one of the default compilers on Windows.

No, xcb will not work on windows. Tunneling X11 does not mean that the xcb stuff is done one your windows system but on your linux host.

Thanks for tip : Solved by : sudo apt install libopengl0 -y Can open now. I appreciate your help

please doing those configuration: /etc/qt5/eglfs_kms_cfg.json { "device": "/dev/dri/card0", "hwcursor": false, "pbuffers": true, "outputs": [ { "name": "VGA1", "mode": "off" }, { "name": "HDMI1", "mode": "1024x768" } ] } Please doing those settings in /etc/profile.d/qt.conf #!/bin/sh export SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt export QT_QPA_EGLFS_KMS_CONFIG=/etc/qt5/eglfs_kms_cfg.json export QT_QPA_EGLFS_INTEGRATION=eglfs_kms export QT_QPA_EGLFS_ALWAYS_SET_MODE=1 export QT_WAYLAND_SHELL_INTEGRATION=wl-shell export QT_QPA_EGLFS_DISABLE_INPUT=1 export QT_QPA_PLATFORM=eglfs /etc/powervr.ini ( file create if not available ) [default] ParamBufferSize=200000000000 MaxParamBufferSize=200000000000 after run #./app

@jsulm unfortunately, same error...

I just had a lot of fun with it myself. I wrote a tool for my work that needs to report to Postgres, not to mention that brought a lot of fun, right? Anyway, looks like there is a ticket (last update almost a year ago) https://bugreports.qt.io/browse/QTBUG-85500 Current solution is to run macdeployqt, then use your own skills with otool and install_name_tool, like I did. In the end I wrote my own script that does all the changes for this one app bundle.

@Christian-Ehrlicher thanks, that worked. Also, copying the styles folder gave me the theme back. Thank you :D

Ok, eventually I found this: https://bugreports.qt.io/browse/QTBUG-72802?focusedCommentId=507973&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-507973 Which is heartbreaking.... WebGL plugin support has been dropped from QT6 onwards....

@hb22 Maybe your application is still being executed (even if there is no window)? On Windows you get this error when you're trying to write/delete an executable which is running.

Would it be possible to have a minimal project to try that on my end so that we can work on the same base ?

Even though I am not a Windows expert, 0xc000007b means that a shared library could not be loaded. While use the 64bit version of minGW, you have provided the 32bit version of opengl. You may wanna try opengl64 instead. You can also start your .exe from a command line window and have a look at the output to obtain more details.

@wang98 I have exactly the same problem on windows 10, although I deployed many apps on windows 8 with qt 5.15.2, on windows 10 I get the error you get. I'll upload the pictures. Is anybody out there who actually deployed qt apps on windows 10. I follow the steps from this tutorial https://wiki.qt.io/Deploy_an_Application_on_Windows and from a Udemy tutorial and from a qt book. Is something that I'm missing, are there any other rules for windows 10? [image: 8c49605c-fc15-4332-822a-800307009982.jpg] [image: 75183b96-7907-4fab-8509-6ad78f8386aa.jpg]
