The OP should also check /etc/ld.so.conf.d and verify that there is an atlas-x86_64.conf file in there. If not: # echo "/usr/lib64/atlas" >/etc/ld.so.conf.d/atlas-x86_64.conf Then, as root, run "ldconfig -v". This will remove the need to specify the "-L" option to the linker. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, C2 Hosting ricks@xxxxxxxx - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - First Law of Work: - - If you can't get it done in the first 24 hours, work nights. - ---------------------------------------------------------------------- -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
