Hi to all, I'm trying to set up a windows environment that can use klayout to evaluate drc and lvs without docker or linux, but there are problems that makes me think it is not possible. I'm using mamba/conda to install docopt and manually cloned the globalfoundries and precheck repositories. Running GlobalFoundries DRC gives this error

I'm posting the drc generated by the

run_drc.py

script, but I think that is more a missing dependency inside Klayout's ruby packed version.

@Farag Elsayed?

We haven't tested Klayout before using windows environment. Everything works fine for same klayout version but for

Ubuntu-22.04

. It seems that your klayout ruby couldn't understand this line no.

29

. I believe you will get extra issues after fixing this.

Thanks a lot for the response. I think the problem might be absense of the pmap package in the windows version of klayout. Maybe if I could install it on the embedded ruby distribution it will work... I'm avoiding this problem using a docker container as development environment, It works fine but drc is slow.
