Hi Gabor! Yes, I believe that's still the case (we're working around it by using different prefixes for each architecture at the moment). And I think we should definitely do what you propose. I'll see if I can get a patch together shortly (or if someone already knows exactly what to do and wants to do it first, feel free! : )).

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,

I will tell Stephen!

I've added iOS as Tier 2 — I bet we can find a sponsor for a buildbot down the line — and I've added myself while I wait to hear from Stephen. It looks like the mailto links on the wiki (e.g. the names in the Platform Maintainers section) aren't working, by the way: http://ghc.haskell.org/trac/ghc/wiki/CodeOwners.

Hello Luke, Thanks for the note. I'm testing on OS X 10.8.4, Xcode 4.6.3, and llvm-gcc 4.2.1 (I placed the scripts directory ghc-ios-scripts-master at the front of PATH). LVM Build is 2336.11.00. I fetched GHC sources and tried to build using: $ git clone git://git.haskell.org/ghc.git $ cd ghc $ ./sync-all --no-dph get $ perl boot # after creating mk/build.mk $ ./configure --target=i386-apple-darwin11 --prefix=/usr/local/ghc-ios-sim/ $ make # Fails saying terminfo -any is not available On Sun, Sep 1, 2013 at 7:39 PM, Luke Iannini wrote:

Hi Dominick, Hm, this should have been fixed by http://ghc.haskell.org/trac/ghc/ticket/7700 .

When you say you downloaded GHC, do you mean you cloned GHC HEAD (e.g. git clone git://git.haskell.org/ghc.git ?) — the patches have only just landed : ).

Also can you give us an idea of what your build environment is? (OS version, Xcode version etc)

Cheers Luke
