来源：互联网发布：汤达人知乎编辑：程序博客网时间：2024/05/12 04:26

参考Sublime Text官方论坛一位中国哥们的回复，通过以下方法完美解决Sublime Text 2中文输入的问题。这几天讨论区老是有人提问，就写个教程吧。

系统：Linux Mint 14 Nadia
输入法：Fcitx 4.2.6.1 PPA。

1. 保存下面的代码为sublime_imfix.c

}

2. 编译动态库：

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

（编译环境和GTK的dev包请自行安装）

3. 设置 LD_PRELOAD 并启动 Sublime Text：

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

为了不用每次启动Sublime Text都打这么一长串东西，写了个启动Sublime的脚本：

?

3
4
5
#!/bin/bash
 
SUBLIME_HOME="/opt/sublime_text"
LD_LIB=$SUBLIME_HOME/libsublime-imfix.so
sh -c "LD_PRELOAD=$LD_LIB $SUBLIME_HOME/sublime_text $@"

（把libsublime-imfix.so放到Sublime Text目录下并修改脚本中的SUBLIME_HOME）
