How do I build simple boost program on Mac OS (Lion) -

-

steps:
1. sudo port boost
boost file installed in /opt/local/boost, library files in /opt/local/lib

2. use xcode create c++ project 

#include <iostream> #include <boost/asio.hpp> int main () {     return 0; }


3. set xcode find out boost
in "build settings" -> "header_search_paths"
in both debug , release add path /opt/local/include

4. "build settings" -> "library_search_paths" --> add /opt/local/lib both debug , release.

5. build program , failed.
error messages,

undefined symbols architecture x86_64:   "boost::system::generic_category()", referenced from:   ___cxx_global_var_init1 in main.o   ___cxx_global_var_init2 in main.o   "boost::system::system_category()", referenced from:   ___cxx_global_var_init3 in main.o   boost::asio::error::get_system_category() in main.o   "boost::asio::error::get_netdb_category()", referenced from:   ___cxx_global_var_init5 in main.o <br>   "boost::asio::error::get_addrinfo_category()", referenced from:   ___cxx_global_var_init6 in main.o <br>   "boost::asio::error::get_misc_category()", referenced from:   ___cxx_global_var_init7 in main.o <br> ld: symbol(s) not found architecture x86_64 clang: error: linker command failed exit code 1 (use -v see invocation)

am wrong in procedure?

you need link boost.system, should in /opt/local/lib/libboost_system (with suffix, depends on how built boost)

add xcode project.
