在Ubuntu安裝Sublime Text 3及支援中文輸入

1.安裝 sublime text 3

1 2 3

sudo add-apt-repository ppa:webupd8team/sublime-text-3 sudo apt-get update sudo apt-get install sublime-text-installer

2.建立sublime-imfix.c

3. 編譯sublime-imfix.c為.so，並複製到 /usr/local/lib/libsublime-imfix.so

1 2	gcc -shared -o libsublime-imfix.so sublime-imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC sudo cp libsublime-imfix.so /usr/local/lib/

4.修改 /usr/bin/subl 執行shell script檔

1 2 3 4

#!/bin/sh export GTK_IM_MODULE=xim export LD_PRELOAD=/usr/local/lib/libsublime-imfix.so exec /opt/sublime_text/sublime_text "$@"

5.必要時重新啟動gcin，並啟動sublime
