[Guo Issac]

Hi. all. 

When I make the the openVoronoi, bellow issued.

Does anybody give me some suggestion to solve it.

my envirenment is debian 9. 

libboost-all-dev version is 1.62.0.1

Can you compile a simple minimal boost python example? For example:

https://github.com/aewallin/sandbox/tree/master/boost_python_helloworld

(that one is updated 3 years ago, I don't know if it works with the latest boost python).

I would guess there is some basic problem with boost python in your install, or the openvoronoi cmake file nees updating to support the latest version of boost.

Dear Anders.

I make your test flies.

Bellowed is the printing. It is passed.

I removed the python 2.7 version requirement from the openvoronoi CMakeLists.

After that it seems to compile OK on my system.

cmake and make output is as follows:

Still building error.

The error message completely same with my first issue report,

It is:

Some googling would suggest maybe:

"Looks like you're trying to build with python3, and boost.python is built with python2. Please check this post:"

https://stackoverflow.com/questions/25188861/libboost-python3-so-1-56-0-undefined-symbol-pyclass-type

does your output of "cmake" show any clues?

if the minimal boost-python example worked - can you run it via python (what version?)

I removed the "2.7" requirement yesterday from cmakelists - so try to pull from github again.

And the test.py can be running by python, v 2.7

 If I key in  python3 test.py

It cannot run.

[Guo Issac]

I disable the BUILD_PYTHON_MODULE in cmake-gui,

the building pass now.
