for installing a specific package (in this case, “make”) from Tumbleweed, it seems the safest and easiest way should be to use yast, and add Tumbleweed to the list of repositories. But it is not listed unter “Community repositories”, and nothing else seems to apply? How can I add Tumbleweed to the list of repositories?
The information under https://en.opensuse.org/Portal:Tumbleweed
seems to be related only for using Tumbleweed as a full distribution, doesn’t speak about installing specific packages.
The package I want to install is https://software.opensuse.org/package/make
Unfortunately there is no more information (like Git-id) given there. Anyway, it would be worth a try. However, the machine where the (hopefully patched) make should be re-installed is a remote server, where only lnyx is available, and apparently direct installation is then not possible.
In the past I made the experience, that zypper is rather error-prone – or at least the results differ from what you get when using yast, and thus I would like not to use it.
Not really a new compiler. Sources are now built with the LTO flag enabled ( Link Time Optimization ). This should lead to smaller and faster binaries. FWIW. Tumbleweed is the 1st linux distro version rebuilt entirely with this option.
@OP: Please take @arvidjaar’s advice serious. There’s already a couple of threads where people did what you suggest. The best result you’ll get is ending up with Tumbleweed instead of Leap, the worst - f.e. with other repos involved - a borked system.
