[SOLVED] error when launching Fcitx5 config tool - Qt related

adr77 · 2025-03-21 22:44:12

Good day, see title for TL:DR, explained further:

After reinstalling Arch on my laptop (new SSD), Fcitx5 wouldn't launch the config tool, first because it was missing then now after trying to launch it in the terminal, this happens:

[andaro@oylmpus ~]$ fcitx5-config-qt
fcitx5-config-qt: error while loading shared libraries: libKF6WindowSystem.so.6: cannot open shared object file: No such file or directory
[andaro@oylmpus ~]$

If anyone could, help, It'd be a pleasure!

solution: just check that you install the `fcitx5-im` package instead of the base `fcitx5` package, also environment variables as well.

Your error is suggesting that your missing some dependencies needed. search up the dependencies for fcitx5-configtool and make sure you have those installed

seth · 2025-03-22 06:59:48

Afaict https://archlinux.org/packages/extra/x8 … dowsystem/ isn't an (optional) dependency for https://archlinux.org/packages/extra/x8 … onfigtool/ (but would only get dragged in implicitly by the KCM stuff) and there's already a package bug reported: https://gitlab.archlinux.org/archlinux/ … -/issues/2

So... what should I do in this case?

I understand it could because something is missing, but how come in my previous Arch install, it would work just fine?

Installing kwindowsystem resolves this.

Okay, so now it launches, but now there's no input but English. I have Japanese input via Mozc, Russian and Hebrew installed. I mapped the "Enumerate Method Input Forward" to LShift+LAlt, but yet nothing happens...

You may inspect the actual environment variable of a certain process by using `xargs -0 -L1 /proc/$PID/environ` for a certain process that you find not working.

## Xim:
1.  `${XMODIFIERS}`:

    **XMODIFIERS is not set**

    **Please set environment variable XMODIFIERS to "@im=fcitx" using the tool your distribution provides or add `export XMODIFIERS=@im=fcitx` to your `~/.xprofile`.

    Xim server name is the same with that set in the environment variable.

3.  qt6 - `${QT_IM_MODULE}`:

    Following error may not be accurate because guessing Qt version from path depends on how your distribution packages Qt. It is not a critical error if you do not use any Qt application with certain version of Qt or you are using text-input support by Qt under Wayland.

One of the things I noticed is that it wanted me to add 'export XMODIFIERS=@im=fcitx' to my '~/.xprofile' file, so I went ahead and did that, I'll update with results after a reboot.

Update: it did nothing.

What is your testcase? Does it work w/ gtk3-demo ?

What's gtk3-demo? I just used Firefox with Google Search.

Oh my, fcitx5-gtk just isn't present... could this have been the issue of it all?

yeah, that was the main problem of it just not working... thanks again!
