编译动态库

编译之前请安装编译环境和GTK，apt-get安装如下：

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

编译动态库，然后将编译的文件libsublime-imfix.so拷贝到Sublime Text 2安装目录下

1
2
# sudo gcc -shared -o libsublime-imfix.so sublime_imfix.c  `pkg-config --libs --cflags gtk+-2.0` -fPIC
# mv libsublime-imfix.so /opt/sublime

启动 Sublime Text 2

进入Sublime Text 2安装目录，执行下述命令启动 Sublime Text 2，查看是否可以使用输入中文

1
2
# cd /opt/sublime
# LD_PRELOAD=./libsublime-imfix.so ./sublime_text

报错：

1
ERROR: ld.so: object 'libsublime-imfix.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

解决方法：
注意：路径要写完整的绝对路径，启动命令修改为

1
# LD_PRELOAD=/opt/sublime/libsublime-imfix.so ./sublime_text

启动Sublime Text 2后，便可输入中文，但是为了不用每次输入一长串命令启动Sublime Text，自己编写一个启动脚本并将修改desktop文件

编写Sublime Text 2启动脚本

编写Sublime Text 2启动脚本/usr/bin/subl

# vim /usr/bin/subl

LD_LIB=$SUBLIME_HOME/libsublime-imfix.so
sh -c "LD_PRELOAD=$LD_LIB $SUBLIME_HOME/sublime_text $@"
# chmod 755 /usr/bin/subl

修改Sublime Text 2启动方式
