[Haskell-cafe] Announcing GHC iOS

[Gabor Greif]

Hi Luke, devs,

Just a quick question, as I haven't recently built a cross-compiler,
but I have noticed a problem with installation of cross-ghc last time.

$ ls <prefix>/lib/ghc-7.7.20130412

The problem is, that when someone installs a non-cross
compiler the same day, the cross-compiler's
libraries and executables get overwritten
by the non-cross installation :-(

This probably also happens with release versions.

Can you confirm this behaviour with HEAD?

In case yes, should we consider adding a
cross-prefix, like employed in bin/ ?

$ ls <prefix>/bin/powerpc-montavista-linux-gnuspe-ghc-pkg-7.7.20130412

Of course all the links inside must be re-aligned accordingly.

Cheers,

    Gabor
