Re: [Haskell-cafe] Announcing GHC iOS

3 Sep 2013


      I've added a ticket to trac with the patch (I don't have commit access)
http://ghc.haskell.org/trac/ghc/ticket/8217
Cheers

Thanks!
This seems to do the trick wonderfully.
-ghclibdir     = $(libdir)/ghc-$(ProjectVersion)
+ghclibdir     = $(libdir)/$(CrossCompilePrefix)ghc-$(ProjectVersion)
I've just done a clean build with this and it's working perfectly.
Great! Do you plan to push this? (Please do!)
Cheers,
Gabor

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! : )).
This is probably where one should start,
https://github.com/ghc/ghc/blob/master/mk/install.mk.in#L108
but be careful with the 'if's in the makefile!

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

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.
Cheers
