Cool. Looks good.
cabal --with-ghc=<cross-ghc> --with-ld=<ld> ...
Ah, in my case the GHC I built was called ghc-7.7.20130116, so it didn't clash with anything else in .cabal. You could also configure your cabal to put the arch/os in the directory name.
~/.cabal/bin ?
I'm thinking mainly about libraries here, yes if you want to build binaries then there needs to be a prefix on the bin dir too.
Nothing in ~/.cabal looks prefixed to me, by default. Maybe my cabal is just old.
The defaults are: install-dirs user -- prefix: /home/simonmar/.cabal -- bindir: $prefix/bin -- libdir: $prefix/lib -- libsubdir: $pkgid/$compiler -- libexecdir: $prefix/libexec -- datadir: $prefix/share -- datasubdir: $pkgid -- docdir: $datadir/doc/$pkgid -- htmldir: $docdir/html -- haddockdir: $htmldir that is, libs go in .cabal/lib/$pkgid/$compiler by default. I just discovered that cabal isn't using the target $arch/$os though, so I've filed a bug: https://github.com/haskell/cabal/issues/1184
Do I need to tell it where to find ghc-pkg, or does that not matter?
No, cabal will find it. Cheers, Simon
