2.建立sublime-imfix.c
/*
sublime-imfix.c
Use LD_PRELOAD to interpose some function to fix sublime input method support for linux.
By Cjacker Huang
By whitequark@whitequark.org
How to compile:
gcc -shared -o libsublime-imfix.so sublime_imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC
How to use:
LD_PRELOAD=./libsublime-imfix.so sublime_text
Changes:
2014 06-09
1, Fix cursor position update for sublime text 3.
2, Combine the codes from whitequark(fix for xim immodule) and add cursor update support for XIM immodule.

3. 編譯sublime-imfix.c為.so，並複製到 /usr/local/lib/libsublime-imfix.so
gcc -shared -o libsublime-imfix.so sublime-imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC sudo cp libsublime-imfix.so /usr/local/lib/
4.修改 /usr/bin/subl 執行shell script檔
#!/bin/sh export GTK_IM_MODULE=xim export LD_PRELOAD=/usr/local/lib/libsublime-imfix.so exec /opt/sublime_text/sublime_text "$@"
5.必要時重新啟動gcin，並啟動sublime
