I have tried to install a c++ code with boost/python in MacOS. The cmake step is fine. This is what I used for configuring.
export CC=/usr/local/bin/gcc
export CXX=/usr/local/bin/g++
export CPP=/usr/local/bin/cpp
export LD=/usr/local/bin/gcc
alias c++=/usr/local/bin/c++
alias g++=/usr/local/bin/g++
alias gcc=/usr/local/bin/gcc
alias cpp=/usr/local/bin/cpp
alias ld=/usr/local/bin/gcc
alias cc=/usr/local/bin/gcc
I received the following errors:
typeinfo for boost::python::objects::caller_py_function_impl<boost::python::detail::caller<void (liblibra::libcontext::Context::*)(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::vector<int, std::allocator<int> >), boost::python::default_call_policies, boost::mpl::vector4<void, liblibra::libcontext::Context&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::vector<int, std::allocator<int> > > > > in libcontext_stat.a(libcontext.cpp.o)
...
ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status
Not sure if this issue is related to the Boost/python. I installed the same code on cenos without any issue. But just has issue when install it on macos. Could anyone help me figure this out? Below is part of the CMAKELIST.txt file I have used:

Thank you guys for your helps.
