[Interest] Could NOT find Qt6WebSockets trying to compile Qt 6.2.6 (Ubuntu 22.04)

[Axel Spoerl]

Hi Stefan,
is the intention to build with or without web sockets?
It looks like a dependency to websockets causes CMake to search for it.
Could you share the configure output?
Brgds
Axel

Thanks.

Meanwhile, I'm trying to compile on Ubuntu 20.04 (note that all of this is done in docker containers).

I'm still observing the same issue, even after a fresh start with an entirely new build tree:

Updating '/home/user/srcdir/qt-build/build/qtbase/share/qt5/translations/qtwebsockets_en.qm'...
lrelease error: cannot create '/home/user/srcdir/qt-build/build/qtbase/share/qt5/translations/qtwebsockets_en.qm': No such file or directory
make[2]: *** [qttranslations/translations/CMakeFiles/updateqm-qtwebsockets_en.ts.dir/build.make:70: qttranslations/translations/CMakeFiles/updateqm-qtwebsockets_en.ts] Error 1

We're testing Ubuntu 22.04 at present.
Can't confirm a date though.

Thanks. Is there a plan for any other LTS release that will work with Ubuntu 22.04 ?

Hi Stefan,
pls note that Ubuntu 20.04 is supported on 6.2. Ubuntu 22.04 is known to have issues.
However, if compiling w/o websockets is the goal, wiping the build tree and deleting websockets from the source tree is likely to help.
Sorry for accidently squashing both issues together.
Cheers
Axel

[sorry, forgot to reply to the list]

Thanks for following up. This issue is different from the previous
one, and downgrading cmake to 3.24.x doesn't make any difference. I
still do get the warning from the `configure` process, and the build
error during `make` execution.

Thanks,

Good morning Stefan,
provided the build is on Linux, this is a known issue (https://bugreports.qt.io/browse/QTBUG-109046), fixed in 6.4.2.
A workaround is downgrading to CMake 3.24 (3.24.2 working for me, 3.24.3 should also work).
Brgds
Axel

Betreff: [Interest] Could NOT find Qt6WebSockets trying to compile Qt 6.2.6 (Ubuntu 22.04)

I'm trying to compile Qt 6.2.6 from source (using the qt-everywhere-src-6.2.6.tar.xz  source package) following instructions from https://doc.qt.io/qt-6.2/build-sources.html, and I get the following error:

-- Could NOT find Qt6WebSockets (missing: Qt6WebSockets_DIR)
CMake Warning at /home/user/srcdir/qt-build/build/qtbase/lib/cmake/Qt6/Qt6Config.cmake:263 (message):
 Failed to find Qt component "WebSockets".

 Expected Config file at
 "/home/user/srcdir/qt-build/build/qtbase/lib/cmake/Qt6WebSockets/Qt6WebSocketsConfig.cmake"
 does NOT exist

Configuring again with the additional option `-skip qtwebsockets` then lets me compile Qt, but ultimately yields this error:

lrelease error: cannot create '/home/user/srcdir/qt-build/build/qtbase/share/qt6/translations/qtwebsockets_en.qm': No such file
or directory

Any idea what the problem is ?

Thanks,
