Installation and Deployment

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.

Enjoy.

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

I just realized something: Qt follows the same policies as Apple for backward compatibility. This means the current version of macOS and the two previous. So there might also be that to take into account for your own supported versions of macOS.

Hence postpone a bit the retiring of Qt 5 for the people using older versions of macOS that you still would like to support.

It's not unseen to have two versions (sometimes even more) versions of an application to support various flavors of macOS. Think PPC to x86_64 migration and now x86_64 to ARM migration.

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.

Cannot be installed on macOS. A silly bug that hasn't been fixed for 1 year

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.

@SGaist said in Can't load sql drivers when configuring and building Qt 6.8.1 from source on linux/Ubuntu 24.04.1:

On a side note, stop working as root. There's no need for that for any build activity.

I have noticed a pattern and clearly I need to change a bad habit. Thank you.

Hi and welcome to devnet,

Can you share the exact message you are getting ?
One path that looks strange is the one from the QtGui framework.

Which compiler are you using ?

Finally got it working with this mirror

.\installer.exe --mirror https://mirrors.ustc.edu.cn/qtproject/
