Build failed on Ubuntu 22.04

[hien-ngo29]

I followed the build instruction on /docs/build_on_linux.md. It was configured successfully until I compiled it with make.
Here's the log:

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:

notes/CMakeLists.txt

Line 35 in 10bed34

set(CMAKE_AUTORCC ON)

And retry the build steps from the beginning?

[hien-ngo29]

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

[zjeffer]

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

[hien-ngo29]

Yes, I did

[hien-ngo29]

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...

[hien-ngo29]

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

notes/CMakeLists.txt

Line 64 in 10bed34

find_package(QT NAMES Qt6 QUIET)

to:

find_package(QT NAMES Qt5 QUIET)

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.

Assuming the Qt bug report I linked in #650 (comment) is the root cause of this, I believe this one can be finally closed, because that bug has been fixed in Qt 6.2.2, and Ubuntu 22.04 already has Qt 6.2.4.

But feel free to reopen if the issue still persists.
