Missing -lpython3.6m error while building hoom2.9.7 from source

[Alexander Patapoff]

Hello,

I've been attempting to build hoomd-2.9.7 from source on as a user on a server cluster.

After I issue "make -j4", hoomd builds until it reaches an error where the /usr/bin/ld cannot find -lpython3.6m. From what I've put together the -lpython3.6m is a library that needs to get linked ( I think ). I've tried using the shared python3 dist, creating a venv of the shared python3 dist, installing a new local python3 dist and making that the default call for path and pythonpath. While each of these attempts caused other fixable errors, I always end up back to this issue. Does anyone have any idea how to move forward with this issue?

thanks!

Alexander,

Some Linux distributions don't include the python3.6m shared library by default. It is not needed to build the HOOMD Python module, only the unit tests implemented in C++. You should be able to disable the BUILD_TESTING option in CMake and complete the build:

In the build directory, run:
cmake . -DBUILD_TESTING=off
