Installation and Deployment

Hi,

Did anything change such as an update to the toolchain, Windows, anti-virus, etc. ?

Would it be all right?I need your help.
Thank you very much for your reply.

And you open a new can of worm: what do you do when bugs (especially security issues) are found in glibc ?

Yes it return a valid pointer

qDebug() << selectionModel(); output QItemSelectionModel(0x6e39580) qDebug() << selectionModel()->model(); output QSortFilterProxyModel(0x6e34008) Debug Assertion Failed!

From the stack trace, I deduce that errors occur when the QModelIndex is removed

I'm not sure if this helps, but when I manually set the selectedIndex to (0, 0), the error doesn't occur.

Just guessing: try disabling your anti-virus.

I have no idea, based on quick googling I would suggest CentOS 7 apparently the last one that shipped with qt3 bindings?

Hi,

You should rather bring this question to the development mailing list. You'll find there Qt developers/maintainers. This forum is more user oriented.

Wel, the probleim is found... MinGW should literally POISON your PATH env variable otherwise it will fail to run GCC itself...

@VamsiDev said in Online installer SSL handshake fail:

in linux how we can fix mirrors in linux can give me a solution to fix this

Like shown in the link posted in this thread: https://wiki.qt.io/Online_Installer_4.x#Selecting_a_mirror_for_opensource

@jsulm i install all the dependencies and then excute configure again and solve my problem.
thanks bro

@SGaist Hello, I switched to using OpenCV lib and a USB Camera instead of a CSI (Camera Serial Interface) Camera. I am able to build and run the application but it's a plain C++ application. I'll work on this more....

For some reasons I had to click on "Re-configure with initial parameters" and now the variables have the correct path.

Seems like the problem is that configure is finding a python.exe which is in the:
C:\Users\Lionel\AppData\Local\Microsoft\WindowsApps\python.exe

But this is a 'shortcut' to install python from windows store, not an actual python interpreter path. I'm experimenting how to resolve it.

I can also see, that building Qt5 relies on Python27. It might be good just to prepend the inital 'configure' with setting python path to:
set PATH=c:\Python27;%PATH%

@NathanJS
I performed exactly the same procedure and encountered the same problem, but even running the command with "sudo" does not change anything.

Debian 12 on wsl2 with gcc 12.2.0

@kumaran13 Do exactly what the error message suggests

Hi and welcome to devnet,

This rather looks like an online installation.

As the error message suggests, try a different mirror.
