Building GHC on OS X

[Simon Peyton-Jones]

You have to build the libraries before you build stage2.  (the stage2
compiler relies on the libraries!)  Just sit in the root directory of
the tree (just above libraries/ and compiler/) and type 'make'.

The library error message was a compiler bug, fixed yesterday. It should
work now.

| Subject: Building GHC on OS X
| 
| Hi,
| 
| I've been using ghc on Mac OS X for a while now, so when I noticed
| Simon Marlow's call (made last month, but I just noticed it) for
people
| to help with OS X, I thought, why not?
| 
| Well, it turns out that I can't even build ghc, so I'm not likely to
| end up being much help.  But it would be nice to at least be able to
| build the thing, so if anybody can help me...
| 
| I'm trying to build GHC (6.5.?? ... version from darcs.haskell.org as
| of yesterday) on Mac OS X (10.4.7 ppc) bootstrapping from ghc 6.4.2
| and gcc 4.0.1.
| 
| "./configure; make" does not work.  On my initial try, I ran into the
| UNDO_DELETE, etc problems associated with Darwin's partial readline
| support described in ticket #766.  The fix suggested in that ticket
| seems to work fine, but not until I installed the GNU readline
library.
| (If the change to detect the broken Darwin readline is in the
| repository,
| it did not work for me).
| 
| After fixing the readline problem, it looks like I can build at least
| part of the stage1 compiler -- but the build fails just after starting
| to build stage2.  The final error is:
|

| 
| After that, there are a handful of errors complaining about things
that
| can't be found (e.g.)
| 
|  > CPUTime.hs:5:0:
|  >    Failed to load interface for `System.CPUTime':
|  >	Could not find module `System.CPUTime':
|  >	  use -v to see a list of the files searched for
|  > make[2]: *** [CPUTime.o] Error 1
| 
| and
| 
|  > Language/Haskell/TH/Syntax.hs:46:0:
|  >    Failed to load interface for `Data.PackedString':
|  >	Could not find module `Data.PackedString':
|  >	  use -v to see a list of the files searched for
|  > make[2]: *** [Language/Haskell/TH/Syntax.o] Error 1
| 
| There are six or seven more messages like those, but nothing severe
| enough to
| stop make until the problem where it can not find 'GHC.Exts'.
| 
| I tried to brute force it with 'make -k', which went a lot further,
| but in the end build nothing useful.
| 
| Anybody have any ideas?  Or build instructions for OS X?
| 
| Thanks,
|
