Getting c++: fatal error: Killed signal terminated program cc1plus while builiding

[jandom]

Hi there,

First of all many thanks for this fenomenal clean Dockerfile and a great example of how to dockerize RDKit (or anything else really).

Bumped into a small problem, getting this error during builds

c++: fatal error: Killed signal terminated program cc1plus

It's not super clear from the error what the problem is – googling around it's clearly a memory error.

Fixed it by upping the docker accessible memory from 2GB to 3GB. Documenting it here in case other people stumble and get confused.
