Practically speaking, it sometimes works, as you can see. But it's not officially supported. Minor version bumps - 8.4 -> 8.5, 8.5 -> 8.6 - are allowed to (and do) break API and ABI compatibility for Tcl. Fedora's Tcl policy explicitly requires Tcl packages install to Tcl version-dependent directories in order to ensure that all code is run with the Tcl minor version level it was built (or 'built') for, so I doubt its maintainer would be in favour of symlink hacks... > If 8.4 apps run fine on 8.5 and 8.6, perhaps we could add the > necessary symlinks. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Fedora Talk: adamwill AT fedoraproject DOT org http://www.happyassassin.net -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
