Installation and Deployment

It looks like something was not properly signed hence the crash.

It turns out that the required name is not listed in the documentation. The following gets the expected result: installer.setMessageBoxAutomaticAnswer("installationErrorWithCancel", QMessageBox.Ignore); I discovered this by inspecting the source and knowing how it works I see that the clue for this is this line in the log: installationErrorWithCancel : Installer Error : Error during installation process (com.microsoft.vcredist):

Build from source. Manually add qmake.exe path to Qt Versions in Preferences:Kits. [image: 86e8eea6-c670-412c-b68f-d88ebfefb0b5.png] Enjoy.

This seems to have been fixed by changing my mirror to "http://qt.mirror.constant.com" as per a stack exchange post.

Hi, You should limit the build to one thread to see exactly where it is failing currently. Your full log is not available anymore.

Had the same issue. Running sudo apt install libgl1-mesa-dev solved it as suggested by this answer.

Hi, Did you already check the bug report system ? I have a vague memory seeing a thread on the Qt mailing list recently about a similar issue.

Switch to vs2022 dont forget to install atl then error on install, the prefix path must not have " " in name (im under windows remember) i had to disable webkit and webengine, ill try to reenable webengine after I get qtcreator to build

Try using a VPN and check whether you still get this issue.

Hi and welcome to devnet, Please turn off your caps lock. Writing all in upper case is considered shouting and rude in written language. Since a long time, the offline installer has become a feature only for commercial users.

The "dd" (line 3.) from soniksaint did the trick.

I found solution, the problem was - I make console app in qt creator with mingw compiler, but tesseract and leptonica was build by vcpkg with msvc compiler. When I try link them to console app then I got this error I post above. If I switch mingw in qt creator to msvc then these libs works all right. I also rebuild tesseract and leptonica with mingw and link them to console app also using mingw and it also work just fine. So it was my fault, I use another compiler to build app (mingw) and another to build libraries (msvc), but thanks for help, now everything works good and I can keep working on my application.

Which compiler are you using ?

Finally got it working with this mirror .\installer.exe --mirror https://mirrors.ustc.edu.cn/qtproject/

Hi and welcome to devnet, You seem to be hitting a faulty mirror. Retry with a different one.

Was this error ever resolved @Buket ?

@Madzi That sounds right. For UI projects you don't need to spawn a terminal, but for console ones you do. It's a per-project setting.

Try with the following installer command with mirror: ./qt-online-installer-linux-x64-4.8.1_1.run --mirror "https://mirrors.ustc.edu.cn/qtproject" If you are installing it for windows, use the windows online installer file. Hopefully, it works.
