sublime text 3怎么在Ubuntu下支持中文输入

• 相关依赖软件的安装---sudo apt-get install build-essential libgtk2.0-dev
• 复制下面代码到sublime text 3中，并保存为名为sublime_imfix.c的文件

        gtk_im_context_set_cursor_location(local_context, rectangle);

• 在终端找到文件位置，将这个文件编译成共享库libsublime-imfix.so----输入命令
  gcc -shared -o libsublime-imfix.so sublime_imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC
• 将libsublime-imfix.so拷贝到sublime_text所在文件夹---sudo mv libsublime-imfix.so /opt/sublime_text/
• 修改文件/usr/bin/subl的内容---sudo gedit /usr/bin/subl
• 将

#!/bin/sh
exec /opt/sublime_text/sublime_text "$@"

• 修改为

#!/bin/sh
LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text "$@"

这样，我们从终端输入subl启动，就能在sublime中输入中文了！

最后，为了方便我们直接启动时，也能使用中文输入，我们需要在终端命令打开和修改文件sublime_text.desktop的内容---sudo gedit /usr/share/applications/sublime_text.desktop

[Desktop Entry]

Name=New File
Exec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text --command new_file"

将内容替换为上面代码内容，这样，我们就大功告成了！当然，为了稳定，我们还是从终端启动更好！

*注
因为我们会看到两个图标，其中一个启动才是可以输入中文的，另一个则还是不能输入
