Device: Orange pi 5 v1.21 arm
OS: Debian 12
Qt version:6.8.1
Qt Creator: 14.0.2

Summary
Unable to build any Qt projects as i'm getting the following error, as i understand Debian 12 comes with GLIBCXX_3.4.30. Support needed in resolving this issue

/opt/Qt/6.8.1/gcc_arm64/libexec/qmlimportscanner:-1: /lib/aarch64-linux-gnu/libstdc++.so.6: version **GLIBCXX_3.4.32'** not found (required by /opt/Qt/6.8.1/gcc_arm64/libexec/qmlimportscanner) /opt/Qt/6.8.1/gcc_arm64/libexec/qmlimportscanner:-1: /lib/aarch64-linux-gnu/libm.so.6: version GLIBC_2.38' not found (required by /opt/Qt/6.8.1/gcc_arm64/libexec/../lib/libQt6Qml.so.6)

If you look at https://doc.qt.io/qt-6.8/supported-platforms.html you can see:

Ubuntu 24.04	x86_64, arm64	GCC as provided by Canonical, GCC 13.x
Debian 11.6	x86_64, arm64	GCC 10 Technology Preview

So your Debian is too new. You have these options:

Pick Debian 11.6 or Ubuntu 24.04
Recompile Qt 6.8.1 for your Debian 12
Use Qt from your Debian 12 distribution

@cristian-adam thanks for the swift reply.
I'm required to use only debian 12 for my project and I did try the 2nd option a while back but i face another issue there.

Here's some context,
I'm trying to build the Qt VNC sample application https://doc.qt.io/QtVNCServer/qtvncserver-remotedesktop-example.html, which requires the QtVncServer module. However, after manually installing Qt 6.8.1 from qt-everywhere-src-6.8.1.zip, I couldn't find this module which is causing the Qt VNC project build to fail.

I don't have the error log at the moment, but I can try running the build again to check it.

I’d like to know whether the QtVncServer module can only be enabled through the Qt Installer or if there’s another way to install it.

QtVncServer is part of the commercial offering, as seen at https://doc.qt.io/QtVNCServer/index.html

You might need to look somewhere else than qt-everywhere-src-6.8.1.zip.

Understood. Thanks
