build failed with ghc 7.2.1 #1

Closed yihuang closed 13 years ago

yihuang commented 13 years ago

Error message:

Implicit import declaration: base:Prelude can't be safely imported! The package (base) the module resides in isn't trusted.

It turns out this has nothing to do with xhtml package, after i mark base package as trusted, this problem disappears:

ghc-pkg trust base

I have been meaning to sort this out -- it’s a bug in 7.2.1 which I should have worked around by now.

Here is what I was told:

Yes sorry I should have warned you about this but forgot. We accidentally released 7.2.1 with a bug in that packages aren't trusted by default (so base isn't trusted). We are changing the behaviour in 7.4.1 so this won't be a problem any more.

For now I suggest you either keep the Safe Haskell patch only in the source repo and not in a released version of xhtml. OR try putting this in the .cabal file:

 ghc-options: -trust base

Others have reported success with this.

Cheers,

Chris

This issue is fixed in ghc-7.2.2.

cdornan commented 13 years ago

Yes it is indeed on 7.2.2 but Hackage is still reporting it as broken. This should be fixed with a new release to fix issue #2 -- as soon as I can get it done.

Thanks!

Chris
