Right, I didn't know that autoconf would automatically look for the

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
