色碼擷取器 - Gpick安裝教學（失敗版）

官網：https://code.google.com/p/gpick/
可使用 yum 安裝，來源是EPEL，但是版本當然不是最新的。
以下是安裝最新版本的步驟。

下載gpick套件，但是格式為deb檔，因此要轉換成CentOS可以安裝的格式，轉換工具為alien。

# mkdir -p /data/src
# wget https://gpick.googlecode.com/files/gpick_0.2.5-1_i386.deb
# wget http://ftp.de.debian.org/debian/pool/main/a/alien/alien_8.90.tar.gz
# tar zxf alien_8.90.tar.gz
# cd alien

    libstdc++.so.6(GLIBCXX_3.4.15) is needed by gpick-0.2.5-2.i386
註：deb轉換rpm參考文獻

安裝 liblua5.2.so.0

# wget http://mirrors.kernel.org/ubuntu/pool/main/l/lua5.2/liblua5.2-0_5.2.2-1_i386.deb
# alien -r liblua5.2-0_5.2.2-1_i386.deb
# rpm -ivh liblua5.2-0-5.2.2-2.i386.rpm


查詢 GLIBCXX 版本

# find / -name libstdc++.so.6
  /usr/lib/libstdc++.so.6
# strings /usr/lib/libstdc++.so.6 | grep GLIBCXX
  ...略
  GLIBCXX_3.4.11

安裝 libstdc++.so.6(GLIBCXX_3.4.15)

我想是我目前的功力還不夠解決＂libstdc++.so.6(GLIBCXX_3.4.15) is needed by gpick-0.2.5-2.i386＂這個問題，以後有時間再來奮戰吧！
