@Tim Edwards first I’ve ever heard of this happening, sorry- can you share the output from ‘which klayout’ and ‘file $(which klayout)’

Don't be sorry. I cause all my own problems. : )

"which klayout" returns

/usr/local/bin/klayout

and "file /usr/local/bin/klayout" returns

/usr/local/bin/klayout: POSIX shell script, ASCII text executable

The /usr/local/bin/klayout script is three lines long, so here it is:

Copy code

#!/bin/sh
export LD_LIBRARY_PATH=/usr/local/share/klayout
/usr/local/share/klayout/klayout -e

And I think that answers my question (and is probably just another of my own self-inflicted wounds).

Okay, so with your observation, I fixed my stupid problem. Now klayout runs properly in batch. That has uncovered another weird error. Klayout is running fine in batch for generating GDS. But when it gets to the XOR step, I get the following output:

Copy code

[ERROR]: during executing: "klayout -b -r /home/tim/gits/openlane/scripts/klayout/xor.drc -rd a=/home/tim/gits/caravel_openframe_project/openlane/picosoc/runs/RUN_2023.08.29_15.08.17/results/signoff/picosoc.gds -rd b=/home/tim/gits/caravel_openframe_project/openlane/picosoc/runs/RUN_2023.08.29_15.08.17/results/signoff/picosoc.klayout.gds -rd jobs=1 -rd rdb_out=/home/tim/gits/caravel_openframe_project/openlane/picosoc/runs/RUN_2023.08.29_15.08.17/reports/signoff/37-xor.xml -rd ignore=81/14 -rd rpt_out=/home/tim/gits/caravel_openframe_project/openlane/picosoc/runs/RUN_2023.08.29_15.08.17/reports/signoff/37-xor.rpt |& tee /dev/null /home/tim/gits/caravel_openframe_project/openlane/picosoc/runs/RUN_2023.08.29_15.08.17/logs/signoff/37-xor.log"

Seems kind of odd that klayout won't recognize the file type of a file that starts with a shebang line stating that it is a ruby script. And I'm not sure why it's just my local version of klayout that's doing this. Any ideas?
