Linking boost libraries
提问by Ramy Al Zuhouri
I have downloaded the boost library (version 1.46.1), but I don't know how to link it through xcode.I found an old question says to put the -lfftw3 flag, so I've put it.
I also added the path: /home/Documents/C++/boost_1_46_1 (it's the directory where I have put the library), but I am getting an error from the linker:
我已经下载了 boost 库（版本 1.46.1），但我不知道如何通过 xcode 链接它。我发现一个老问题说要放置 -lfftw3 标志，所以我已经放置了它。
我还添加了路径：/home/Documents/C++/boost_1_46_1（这是我放置库的目录），但是我从链接器收到错误：
ld: warning: directory not found for option '-L/home/ramy/Documents/C++/boost_1_46_1'
ld: library not found for -lfftw3
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Command /Developer/usr/bin/clang++ failed with exit code 1
So the question are two:
1)How to manage xcode to link boost?
2)Where to put the library in file system? In linux there was /usr/lib, here there isn't this path, should I put it in /Developer/usr/lib?
所以问题是两个：
1）如何管理 xcode 链接提升？
2）将库放在文件系统中的什么位置？linux有/usr/lib，这里没有这个路径，我应该把它放在/Developer/usr/lib中吗？

Or for those who are looking for a quick answer (and are on linux), the magic is simply to add the following flags:
或者对于那些正在寻找快速答案的人（并且在 linux 上），魔术只是添加以下标志：
-l boost_system
