裝wing時看到這個錯誤訊息
Your C++ compiler (g++) is not a GNU C++ compiler!
Either set the 'CXX' environment variable to tell me where
a GNU C++ compiler is, or compile at your own risk.
(This code uses a few GCC extensions and GCC-specific compiler options,
and Linux header files are GCC-specific.)
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
--------------------
解決方法是：
apt-get install g++

沒裝g++ = ="

更改android 1.6版的 market登入用帳號密碼 (for 1.6)
這個是很舊的版本, 1.6的 (HTC magic)
現在的android應該不能用這個方法了 XD
----------------------------------------------------------
之前拿lab手機 要登入market時叫我輸入密碼
密碼又不是我的 最好我會知道啊 XD
大部分查到的資訊都是要回覆出廠設定
後來照著這篇的步驟就成功變更帳號了
http://www.shekhargovindarajan.com/google/android-how-to-change-the-google-account-without-a-hard-reset/
不用回覆出廠設定 XD
簡單說：
1. 去setting
2. Applications -> Manage Applications -> 進入Google Apps, 選Clear data
3. 進入Data synchronization, 選Clear data
然後就可以換帳號了 XD
