ld: library not found for -lboost_python on MacOS

Question

On Mac, I want to build the example Boost.Python code

hello.cpp

#include 

char const* greet()
{
    return          


        

Answer 1

Finally, I found there is no such libboost_python37.dylib in boost-python lib path

$ ls /usr/local/Cellar/boost-python3/1.67.0_1/lib
libboost_numpy37-mt.a      libboost_numpy37.a         libboost_python37-mt.dylib libboost_python37.dylib
libboost_numpy37-mt.dylib  libboost_numpy37.dylib     libboost_python37-mt.a     libboost_python37.a

So I created a soft link

$ sudo ln -s libboost_python37.dylib libboost_python3.dylib

I can compile my code now.
