Installation and Deployment

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.

Hi,

Not a direct answer but I would recommend using the MinGW version provided by the Qt online installer. That one is the same that has been used to build the Qt version available through said installer.

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/

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.

"refresh the installer." = click "Filter"

Thank you

@SGaist I restarted the PC and opened Qt Creator. Everything went back to normal. The cache memory of Qt Creator seems to have cleared.
