I'm trying to create a directory in C++ (compiling with Clang) on Mac Yosemite with Boost (Boost was installed via Macports). This is what my code looks like:

#include <boost/filesystem.hpp> // header at top of file boost::filesystem::path path("/Users/u5305887/Desktop/ti"); // code in main function boost::filesystem::create_directories( path );

However, when I compile it, I get the following error:

Undefined symbols for architecture x86_64: "boost::filesystem::detail::create_directories(boost::filesystem::path const&, boost::system::error_code*)"

I've been trying to Google this error but I can't seem to find any way to fix it. I've double checked my code against a few tutorials and can't see where I've gone wrong.
