Details

Description:
After upgrading to the qt6-tools which rebuild by clang13, all the QML strings with qsTr() method on the translation file become vanished, after removing the old *.ts file, it will only generate the items for C++ codes.

Additional info:
* package version(s)
6.2.1-2
* config and/or log files etc.
* link to upstream bug report, if any

Steps to reproduce:
1. Upgrade to the latest qt6-tools on the mirrors.
2. Add the following configuration on CMakeLists.txt (replace my project name with <project_name>)

qt_add_translations(<project_name>
RESOURCE_PREFIX "/i18n"
TS_FILES
${CMAKE_SOURCE_DIR}/i18n/<project_name>_zh_CN.ts
)

add_dependencies(<project_name> <project_name>_lupdate)

Works fine for qt6ct. Please attach a full affected project.

Project here: https://github.com/ArkToria/ACross/blob/97def9ae59f4f75b7297f3f6e621a89622667eea/CMakeLists.txt#L209. Please help me to review this usage.

Works for me. The generated qm are identical with either qt6-tools version. Please make sure that your system is fully updated and you don't have come other clang version locally installed that is interfering.

I prepared an ASCII animation to reproduce this process：
https://asciinema.org/a/s3VHUAwdx1g5xDR3CyfoAznXp

My distribution is Arch Linux, I notice that issue when the package was on testing, and more version information is as follows:
clang version 13.0.0
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

I notice that the qt upstream has fixed this bug, But the source code tarball used by Arch Linux does not include this change. The QmlDevToolsPrivate component could not be found, and then it was defined QT_NO_QML.

I don't see how that can be related. QmlDevToolsPrivate *does* exist in 6.2, it was only removed in master, and it is found when building qt6-tools:

-- The following packages have been found:
[...]
* Qt6QmlDevToolsPrivate (required version >= 6.2.1)

Found the issue - it's a packaging bug
