再一个程序中，遇到Unresolved inclusion: <iostream>
和Symbol 'std' could not be resolved， 我猜想是有关C++开发的库文件没有导入进来，但是怎么才能导入进来？求解答

Try below commonds, actually, I don't know which of them solved this issue, but now my programs works (sorry, just installed Ubuntu 12.10, haven't install Chinese input software, have to use this):

sudo apt-get install build-essential gcc make
sudo apt-get install libc6 libc6-dev
sudo apt-get install libc++6 libc++6-dev

Good luck.
