The strange package dependence problem: fcitx-frontend-qt5 must be installed for self-compiled fcitx5.

[Hongyi Zhao]

On Ubuntu 20.10, I've compiled and installed the following packages in order of number:

10-cldr-emoji-annotation.git
10-fmt.git
10-librime.git
10-xcb-imdkit.git
20-fcitx5.git
25-libime.git
30-fcitx5-gtk.git
30-fcitx5-lua.git
30-fcitx5-qt.git
30-fcitx5-rime.git
40-fcitx5-chinese-addons.git
40-fcitx5-configtool.git

But it seems that the input methods switch through the frontend of fcitx5 still needed the following package to be installed, otherwise the input methods switch will be disabled and not responds to the keystroke:

$ sudo apt-get install -y fcitx-frontend-qt5

I'm very confused on this problem can't figure out the reason. Any hints will be highly appreciated.

When you compile your own gtk im module, the hook will not update it
automatically.
you need to manually run gtk-query-immodules-3.0 --update-cache for
gtk3 and gtk-query-immodules-2.0 --update-cache for gtk2.
Depending on the distribution, the file may be overwritten by any
related package update.

fcitx-frontend-qt5 is fcitx4's im module, which indeed works with
fcitx 5, for backward compatibility.

Also it is possible that you didn't install them to the directory that
is recognized by system's gtk / qt.

Please run fcitx5-diagnose for more information and post it here if
you don't understand how to interpret it.

(BTW you can use Chinese to reply if you want)

仍然不太清楚甚末时候及如何调用上面的命令。参看如下结果：

werner@X10DAi:~$ gtk-query-immodules-3.0
gtk-query-immodules-3.0: command not found
werner@X10DAi:~$ gtk-query-immodules-2.0
gtk-query-immodules-2.0: command not found

这两个命令在 ubuntu 上没有被安装到 PATH 里面，因为 debian 的 multiarch 的关系

在类似这种目录下面
/usr/lib/x86_64-linux-gnu/libgtk-3-0/gtk-query-immodules-3.0

用这个网站搜索比较方便
https://pkgs.org/search/?q=gtk-query-immodules-3.0
另外可能需要指定 -DGTK3_IM_MODULEDIR=/lib/x86_64-linux-gnu/gtk-3.0/3.0.0/immodules
（gtk2 类似）


而且可以看出 qt im module 安装的路径肯定也不对，因为没有找到
可以编译时用 -DCMAKE_INSTALL_QT5PLUGINDIR 来指定
根据 fcitx5-diagnose 的输出，可以设置为 /lib/x86_64-linux-gnu/qt5/plugins

我一般使用下面的命令：

$ apt-file search -x 'gtk-query-immodules-[0-9.]+$'
libgtk-3-0: /usr/lib/x86_64-linux-gnu/libgtk-3-0/gtk-query-immodules-3.0
libgtk2.0-0: /usr/lib/x86_64-linux-gnu/libgtk2.0-0/gtk-query-immodules-2.0

根据你上面的提示，我执行了下面的命令：

werner@X10DAi:~$ sudo
/usr/lib/x86_64-linux-gnu/libgtk-3-0/gtk-query-immodules-3.0
--update-cache


> 另外可能需要指定 -DGTK3_IM_MODULEDIR=/lib/x86_64-linux-gnu/gtk-3.0/3.0.0/immodules

改为下面的来编译fcitx5-gtk.git：
cmake -DENABLE_GTK2_IM_MODULE=OFF -DENABLE_GTK4_IM_MODULE=OFF
-DGTK3_IM_MODULEDIR=/lib/x86_64-linux-gnu/gtk-3.0/3.0.0/immodules ..

改为下面的来编译fcitx5-qt.git：

cmake -DENABLE_QT4=false
-DCMAKE_INSTALL_QT5PLUGINDIR=/lib/x86_64-linux-gnu/qt5/plugins ..

确实解决了问题。

另外，我想知道，如何采用上面的编译选项，是否就没有必要单独运行的这个命令了：

werner@X10DAi:~$ sudo
/usr/lib/x86_64-linux-gnu/libgtk-3-0/gtk-query-immodules-3.0
--update-cache
