Dear Samuel,
NEST does not actually specify a specific library version to link against, but rather determines the one available on your system during the run of cmake.
If you upgrade your environment, you might have to cmake and compile NEST anew in order for it to pick up the new version. To reduce the risk of having old and new things interfere, it is usually safest to remove the old installation before doing this.
Best regards, Jochen!

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
