Building python_binding

[er3do]

Hello Michal,

I built clandmark with BUILD_SHARED_LIBS = ON, BUILD_PYTHON_BINDINGS = OFF and install it (using checkinstall).

After that I ran ccmake again and set BUILD_PYTHON_BINDINGS = ON. After that running make ends with the following error:

[ 27%] Built target clandmark
[ 54%] Built target flandmark

Can you give me an idea how to fix it?

My env: Ubuntu 16, python 2.7

Hi @er3do,

sorry for a late answer.

It seems that I have broken something when I tried to make the build system working on Windows. I just tried to compile python interface on Linux and, indeed, I got the same error as you did.
Please, try to change the PYTHON_LIBRARY variable in ccmake to the dynamic version (e.g. libpython2.7.so). Then, it should work.
