Therefore you cannot simply install the old Fedora packages of gsl-2.4 and gsl-2.6 in parallel. Depending on your usage scenario, you could compile GSL 2.4 yourself and install it into a private path, then build other stuff (like Perl modules) against it and override $LD_LIBRARY_PATH whenever you want the runtime linker to find the old GSL libs. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
