完美解决 linux sublime 中文无法输入

感谢oschina 中几位前辈的分享　下面是我结合自己的情况所配置的具体步骤：

系统环境： ubuntu 12.10

输入法：fcitx

fcitx 安装 apt-get install fcitx

sublime 安装 apt-get install sublime-text-2

找到sublime-text-2的安装文件包　里面大概有　Ｉcon  lib  PackageSetup.py 等几个文件或者文件夹

我的文件安装包是放在 /opt/sublime_text_2 　

cd /opt/sublime_text_2

新建一个文件 sublime_imfix.c　复制一下代码

保存后退出
如果你的系统没装gcc 和 gtk的话　先装一下　安装方法如下
apt-get install build-essential 　　（安装GCC）  
apt-get install libgtk2.0-dev       （安装ＧＴK）

然后编译一下 
gcc -shared -o libsublime-imfix.so sublime_imfix.c  `pkg-config --libs --cflags gtk+-2.0` -fPIC

　然后转到/usr/bin 　vim subl 这个是快捷启动

　打开subl后　将原有的代码全部注释　符号为＃

　　然后复制下面的代码：

　　SUBLIME_HOME="/opt/sublime_text_2"
　　LD_LIB=$SUBLIME_HOME/libsublime-imfix.so
　　sh -c "LD_PRELOAD=$LD_LIB $SUBLIME_HOME/sublime_text $@"

　　有一点要注意的是 SUBLIME_HOME 这个变量值应该是你的sublime 安装包文件所在。

保存后退出 再启动就OK 了
