Hi Catherine, Thanks for the heads up. Loading auto tools indeed solved the issue.

I followed the install instruction here: https://nest-simulator.readthedocs.io/en/stable/installation/noenv_install.… And source the nest_vars.sh file according to the instructions: `source /p/home/jusers/wybo1/jureca/nest/nest-install/bin/nest_vars.sh` Also, `make installcheck` passes successfully (both from the login node and from a slurm script).
