Build error when building .so library with gcc

[Maurice Vanrumbeke]

g++ -c -o concaveman.o concaveman.cpp
gcc -shared -o concaveman.so concaveman.o

Gives a bunch of errors
Are there any other ways to build to .so library?
I'm trying to build for Python wrappers.

I released a python package based on concaveman-cpp: https://github.com/cubao/concave_hull

Hope this helpful.
