    initial v2  
    66
    77I tried to compile this program with c++11 or without c++11:
    8 
    9     #include <boost/python.hpp>
    10     class A {};
    11     BOOST_PYTHON_MODULE(libblah) {
    12       boost::python::class_<A>("A");
    13     }
     8{{{
     9#include <boost/python.hpp>
     10class A {};
     11BOOST_PYTHON_MODULE(libblah) {
     12    boost::python::class_<A>("A");
     13}
     14}}}
    1415
    1516I used cmake, but the build commands generated are below along with the linker error that I get:

    28 How can I work around this bug without installing boost by myself.  As with this [Related question][1], the symbols in the library
