新建c语言文件sublime_imfix.c，编译成libsublime-imfix.so，编译过程：

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

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

拷贝到Sublime Text 3目录下(默认在/opt/sublime_text下)

编辑subl命令文件：/usr/bin/subl

#!/bin/sh
export LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so

exec /opt/sublime_text/sublime_text "$@"

编辑/usr/share/applications/sublime_text.desktop文件,将里面的/opt/sublime_text/sublime_text换成subl
