pyadolc will not build with boost 1.65 ("obsoleted" boost::python::numeric API)

[paulrozdeba]

The build step of pyadolc, i.e. running
python setup.py build
fails when version 1.65 of boost is installed on the system. The first error message thrown is:

gcc: adolc/src/py_adolc.cpp
In file included from adolc/src/py_adolc.hpp:5:0,
                 from adolc/src/py_adolc.cpp:3:
adolc/src/num_util.h:32:18: error: ‘numeric’ in namespace ‘boost::python’ does not name a type
   boost::python::numeric::array makeNum(boost::python::object x);
                  ^~~~~~~

followed by many similar error messages related to the boost::python::numeric namespace.

According to the boost 1.65.1 release notes:

The boost::python::numeric API has been removed, as it is being obsoleted by boost::python::numpy.

In other words I think the solution may be to change all references to the old namespace to the new numpy namespace. I'm going to try this out and, if it works, submit a pull request.

After changing references to boost::python::numeric to boost::python::numpy, and also taking the error message in my previous comment into account, I think the problem is more complicated. There is some issue with the numpy array dtype being fed to makeNum (scattered throughout num_util.h and num_util.cpp), I'm just not exactly sure what's going on at the moment.

Here's a link to all the error messages I get (on pastebin).

Note: pyadolc still builds successfully with boost 1.64.0 on my system.

Brad Bell might have solved a similar problem for pycppad. I recommend looking at the pycppad build process, before attempting to adapt pyadolc to boost >= 1.65.1.

I don't have time to do it myself but can offer to test and merge a PR.
