[Boost-users] Boost Regex link errors with clang on Mac OS

Linking with Boost Regex delivers this message: Undefined symbols for architecture x86_64: "boost::regex_error::regex_error(std::string const&, boost::regex_constants::error_type, long)", referenced from: boost::re_detail::basic_regex_creator

According to the Stack Overflow link [1], the problem lies in a clang bug. But I updated to the latest version I could find and it's still there. Apparently the BOOST_REGEX_NO_EXTERNAL_TEMPLATES define does work on preventing the hack on the template keyword, on boost/regex/v4/instances.hpp . Anyone else had this bug? Thanks for any help letting me compile without ugly hacks, Rodrigo I'm using Mac OS X 10.8.4, and compiling with C++11.

c++ --version Apple LLVM version 4.2 (clang-425.0.28) (based on LLVM 3.2svn) Target: x86_64-apple-darwin12.4.0 Thread model: posix
