Build failed on Ubuntu 22.04 about notes HOT 9 OPEN

Seems to be related to this bug:

https://bugreports.qt.io/browse/QTBUG-101353

Can you try adding this line:

set(CMAKE_AUTORCC_OPTIONS "--no-zstd")

Below this line:

And retry the build steps from the beginning?

I found 1 more way to build this by using Qt 5 instead of Qt 6

Just so you know, you don't have to edit that file manually. You can invoke cmake with -DUSE_QT_VERSION=5, e.g.:

cmake -B build -USE_QT_VERSION=5 -DCMAKE_BUILD_TYPE=Release

Just keep in mind that the Qt 5 build currently lacks some features compared to a Qt 6 build.

I followed the steps that you said, but it didn't work. The error was still there, nothing changed

from notes.

Did you delete the build folder before making the change and trying again?

from notes.

Yes, I did

Somehow the code was successfully built if I installed Qt by the Qt binaries installer (Not by source.list or any Linux package managers)
So basically, my problem has been resolved for now.

That worked because official Qt binaries were likely built with zstd support, while Qt binaries from Ubuntu repositories were not (apparently).

I'm not sure why tweaking CMAKE_AUTORCC_OPTIONS didn't work...

from notes.

Well.. I found 1 more way to build this by using Qt 5 instead of Qt 6. By changing this line:

find_package(QT NAMES Qt5 QUIET)
