在Ubuntu上安装Sublime Text2并解决无法使用fcitx中文输入法问题

第一步 下载安装


到Sublime Text官网去下载安装包(我这里使用的是64位的)并解压

解压
1
tar xvf Sublime\ Text\ 2.0.2\ x64.tar.bz2

第二步 移动


将解压后的目录移动到/opt/目录下

1
sudo mv Sublime\ Text\ 2 /opt/

第三步 创建符号链接


创建符号链接到/usr/bin/下

1
sudo ln -s /opt/Sublime\ Text\ 2/sublime_text /usr/bin/sublime

第四步 创建启动器


创建并编辑/usr/share/applications/sublime.desktop文件

1
sudo vim /usr/share/applications/sublime.desktop

文件内容如下

  • 编译sublime-imfix.c
    安装必要的编译包
    1
    2
    sudo apt-get install build-essential
    sudo apt-get install libgtk2.0-dev

编译

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

  • 将libsublime-imfix.so移动到/usr/lib/下

    1
    sudo mv libsublime-imfix.so /usr/lib/
  • 修改启动器文件内容
