You have to explicitly enable the python binding.
So you should either run
ad_rss$> colcon build --cmake-args -DBUILD_PYTHON_BINDING=ON -DBUILD_TESTING=ON
Then you finally can also test if the python binding is actually working.

Or you follow the plain CMAKE commands:
https://intel.github.io/ad-rss-lib/BUILDING/index.html#plain-cmake-build
but also there, you have to append the -DBUILD_PYTHON_BINDING=ON to the packages
to achieve the same without colcon...

Thanks for responding @berndgassmann! I tried and it resulted in this error. I have installed boost 1.67. But the error still persisits.

In travis build on ubuntu 16.04 I see:

But in you error logs at least also 1.58.0 is mentioned. In each case you have to check the whole logfile under log/latest/ad_physics to get a bit more than just the error output.

Your error log seems to have problems the boost python-py37 version.
Either the library is actually not available (Boost python-py37) or something else in the boost installation is wrong.

At least it doesn't find the 1.67 version you mentioned. As a quick fix, to overcome the problem you might be able to comment out the python3 variant in
https://github.com/intel/ad-rss-lib/blob/master/cmake/python-binding.cmake
and the same file in the map/cmake/python-binding.cmake file.

As it looks that the python2 variant is working.

Or you somehow replace the check for the lib by the concrete files you have in your system ...

Thanks a lot @berndgassmann .. The issue was I was using python3.7 and i think boost 1.58 doesn't support 3.7. I reinstalled with python 3.5. It worked.

Ok, good that you got down to the root cause of this.
So I'll close this issue.
