Then I have to say it is rather irritating that there is no way for me to safely provide the latest version of cabal-install!
the same problem affects Debian, and I find it equally irritating. Not sure how Fedora handles this – Jens, did you find a problem around this?
I haven't really. I think I will just ship cabal-install-1.18 in Fedora 21 with ghc-7.8.
One possibility would be to manually bundle the Cabal and cabal-install sources into one (dpkg supports source packages with multiple original tarballs), build the new Cabal just to be used to build cabal-install and link that statically (which is the default). This would provide an up-to-date cabal-install binary without having to ship a new Cabal version as a library.
Right, this is what I do in my Copr repo (Fedora equivalent of OBS/PPA).
Or does cabal-install require the matching version
of Cabal to be registered to work? I don't think so, but I believe some of the latest functionality needs Cabal >= 1.18 to work. Alternatively it might be possible to build ghc with a newer Cabal. Not
sure what that might break.
Right that should work I guess. (Personally I still wish for bundling cabal-install with ghc though that doesn't help with this of course, except then you could replace with a newer cabal-install too.;) Jens
