解決 gcin 在 KDE 無法輸入中文 (Ubuntu 16.04)

Posted on Comments:

今天把系統從 Kubuntu 換成 KDE neon User Edition 並裝完 gcin 之後，發現 gcin 不能在 Konsole 中輸入中文。

解決方法很簡單也很困難，簡單之處在於安裝 gcin-qt5-immodule，難也難在安裝 gcin-qt5-immodule

1
~$ sudo apt-get install gcin-qt5-immodule

輸入之後，會出現錯誤：

之前裝 LinuxMint 18 的時候有解過一次這個問題。

解決方法如下

sudo apt download gcin-qt5-immodule
ar x gcin-qt5-immodule_2.8.6+eliu-0_amd64.deb
vim control.tar.gz

將 tarfile::./control 中的 Depends 由

Depends: gcin-im-client (>= 2.8.6+eliu-0), libc6 (>= 2.4), libgcc1 (>= 1:3.0), libqt5core5a (>= 5.0.2), libqt5gui5 (>= 5.4.1) | libqt5gui5-gles (>= 5.4.1), qtbase-abi-5-5-1

改為：

Depends: gcin-im-client (>= 2.8.6+eliu-0), libc6 (>= 2.4), libgcc1 (>= 1:3.0), libqt5core5a (>= 5.0.2), libqt5gui5 (>= 5.4.1) | libqt5gui5-gles (>= 5.4.1)

ar r gcin-qt5-immodule_2.8.6+eliu-0_amd64.deb control.tar.gz
sudo dpkg -i gcin-qt5-immodule_2.8.6+eliu-0_amd64.deb

重新執行 gcin 即可。

也可以直接下載我包好的：Download
