概述
本文记录在 ubuntu 如何修复 Sublime Text 不能输入中文的问题.
问题
在 ubuntu 下安装完 Sublime Text之后,发现不能输入中文,也不能正常的切换成中文输入法.google 了一圈之后,看到网上的解决方案,记录下来,方便日后使用.
解决方案
1. 编译一段C代码.保存以下的代码,并将文件命名为 sublime-imfix.c

2. 因为要编译C代码,所以需要安装C的编译环境
打开命令行,安装编译环境
1
2
|
sudo apt-get install build-essential
sudo apt-get install libgtk2.0-dev
|
3. 编译如上说的C代码,会在当前目录下生成libsublime-imfix.so文件,并将libsublime-imfix.so复制到/opt/sublime_text/目录下.

gcc -shared -o libsublime-imfix.so sublime-imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC
|
4. 修改/usr/share/applications/sublime_text.desktop
1
|
vim sublime_text.desktop
|
然后修改对应的内容
