环境配置：ubuntu 14.10

1.保存下述代码为 sublime_imfix.c 文件

 3 Use LD_PRELOAD to interpose some function to fix sublime input method support for linux.

2.安装C/C++的编译环境和gtk libgtk2.0-dev

1 sudo apt-get install build-essential
2 sudo apt-get install libgtk2.0-dev

3.编译共享内库

1 gcc -shared -o libsublime-imfix.so sublime_imfix.c  `pkg-config --libs --cflags gtk+-2.0` -fPIC

4.启动 Sublime Text 2

1 LD_PRELOAD=./libsublime-imfix.so ./sublime_text

好了～可以输入中文了～

5.添加到环境变量

例如：我的sublime安装在~/Sublime_Text_2/sublime_text下

在.bashrc中添加

1 alias sublime=‘LD_PRELOAD=~/Sublime_Text_2/libsublime-imfix.so ~/Sublime_Text_2/sublime_text‘

即可在命令行中直接输入 sublime 来启动能够输入中文的sublime了～
