Hi, nestsimulator-2.18.0 fails PyNEST installation as requesting libgsl.so.23 while libgsl.so.25 is available (see brelow --1-- log of installcheck for PyNEST tests) cmake reports no errors with GSL (see bleow --2-- log extract of cmake output ) configuration: linux manjaro latest system update 2019-09-05 Sorry for my ignorance : is there a way to force linking with most recent gsl library ? Or is it necessary to install also the old library version somehow? If then how ? Thank you in advance for any help Samuel Bottani --1-- Phase 7: Running PyNEST tests. ------------------------------ Using nosetests.
