clang++ - Boost.Python Link Error with Python3 and virtualenv -

i got following error when tried compile .cpp file clang++.

ld: symbol(s) not found architecture x86_64 clang: error: linker command failed exit code 1 (use -v see invocation) 

---

i set python , boost-python follows.

python

i installed python 3.6.0 using pyenv-virtualenv (via homebrew)

boost-python

i used homebrew in python 3 environment.

$ source activate py36     $ brew install boost-python --with-python3 --without-python 

~/.bash_profile

my ~/.bash_profile looks this:

export pyenv_root="/usr/local/var/pyenv" export pyenv_virtualenv_disable_prompt=1 export cplus_include_path="$cplus_include_path:/usr/local/var/pyenv/versions/3.6.0/include/python3.6m/" if pyenv > /dev/null; eval "$(pyenv init -)"; fi if pyenv-virtualenv-init > /dev/null; eval "$(pyenv virtualenv-init -)" ; fi

test cpp

this file tried compile , failed (saved test.cpp).

#define boost_python_static_lib     #include <boost/python.hpp> using namespace boost::python;  char const* say(){   return "hello, world"; }   boost_python_module( hello ){    boost::python::def( "say", );  }
