caball-install build fails #1411

Closed mimosa67 closed 11 years ago

mimosa67 commented 11 years ago

This may be a local issue, but I'm not really sure how to check. I tried installing using the bootstrap shell script, and by doing ghc --make Setup && ./Setup configure --user && ./Setup build && ./Setup install

(the two deps mentioned are already installed - zlib & HTTP - as well as Cabal (1.14.0))

in both cases producing a similar error:

Distribution/Client/BuildReports/Upload.hs:54:38: Couldn't match expected type Maybe b0' with actual typeURI' In the return type of a call of `relativeTo' In a stmt of a 'do' block: relativeTo rel uri In the expression: do { rel <- parseRelativeReference location; relativeTo rel uri }

ghc is 7.4.2. cabal-install is 0.14.0

The type of Network.URI.relativeTo changed between network-2.3 (URI -> URI -> Maybe URI) and network-2.4 (URI -> URI -> URI). If you want to build cabal-install-0.14.0 you will have to build it with network-2.3.x. Out of curiosity, why are you trying to build cabal-install-0.14.0 from source? That is an old release.

Looks like this is fixed in trunk.

Thanks for getting back to me. I must have followed an old link (from when 0.14.0 was the latest release). I see that cabal-install 1.16.02 requires Cabal >= 1.16.0, but I have already installed 1.14.0.

Should that come out in the wash, or do I need to take active steps to remove it before building a more recent Cabal?

It's perhaps also relevant that the ghc I have isn't the latest - and maybe that has something to do with the Cabal version I ended up downloading: it's 7.6.3. My Linux distro (Salix) is basically Slack, and as such, packages are generally only updated once in each release cycle.

PS Here is the link I must have followed:

http://www.haskell.org/cabal/download.html

It still points to versions ~14~ of Cabal and cabal-install. The text mentions ghc 7.4.1!

7.6.3 is the latest stable release of GHC so no problem there. Having Cabal-1.14.0 installed probably won't do you much harm but you might as well unregister it: ghc-pkg unregister Cabal-1.14.0.

Re: the website, thanks for the heads up, that should indeed be updated. I'm not sure who has access to it.
