How do I build simple boost program on Mac OS (Lion)
boost, osx-lion
Solution
You need to link with `Boost.System`, which should be in `/opt/local/lib/libboost_system` (with some suffix, that depends on how you built boost)
Add that to your Xcode project.
Problem
Steps: 1. sudo port boost The boost file installed in /opt/local/boost, library files are in /opt/local/lib 2. use XCode to create c++ project ``` #include <iostream> #include <boost/asio.hpp> int main () { return 0; } ``` 3. set XCode to find out boost in "Build Settings" -> "HEADER_SEARCH_PATHS" in both Debug and Release add path /opt/local/include 4. "Build Settings" -> "LIBRARY_SEARCH_PATHS" --> add /opt/local/lib both for debug and release. 5. build program and failed. Error Messages, ``` Undefined symbols for 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 for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) ``` Am I wrong in the procedure?
