Hi there,

I installed boost with MacPorts, most library works perfectly except boost::regex. Here is the informations from my dev environment:

$ uname -a

Darwin Kernel Version 13.1.0: Wed Apr 2 23:52:02 PDT 2014; root:xnu-2422.92.1~2/RELEASE_X86_64 x86_64

$ sudo port installed | grep boost

boost @1.55.0_2+no_single+no_static+python27 (active)

here is the source code, quite simple:

$ cat test.cpp

#include <sstream> #include <iostream>

#include <boost/regex.hpp>

int main (int argc, const char* argv[]) { boost::regex exp("*"); boost::regex_match("foo", exp); }

$ g++ --version

$ g++ -std=c++11 -o test -I/opt/local/include -L/opt/local/lib -lboost_regex-mt test.cpp

Would you please help to check this problem? If you need any more information, please let me know.

Thank you!
