Environment

  • Pythonnet version: Latest pip, and latest master
  • Python version: Tried 3.5 and 3.6
  • Operating System: Ubuntu LTS 16.04

Details

First I had an error that pycparser could not be found, so I installed that. But now I get the following log error on Python versions 3.5, a fresh 3.6 install and on both the master branch and the latest pip version.

Edit: I installed the dependencies (that aren't listed anywhere on here?), now I get:

Ok I got it working on 3.5, guess it relates to the other issues here.

I had the same issue building linux docker image with Python 3.7. Solved by installing clang and python-clang like this in the Dockerfile:
RUN apt-get -y install --no-install-recommends clang python-clang

apt-get -y install clang works for me
