#3400: OS X: ghc broken on Snow Leopard

--------------------+-------------------------------------------------------
 I downloaded GHC-6.10.4-i386.pkg and installed it on a OS X 10.6 Snow
 Leopard seed. gcc in Snow Leopard defaults to x86_64. This breaks even
 trivial builds with GHC since it passes either no or incompatible flags.

 GHC should either produce proper x86_64 assembly or pass "-arch i386" to
 force a 32-bit build.

 An example follows.

 == Trivial source: ==
 {{{
 $ cat Foo.hs
 main = do
      putStrLn "Foo!"
 }}}

 == Direct build broken: ==

Comment (by Syzygies):

 I'm posting some links of interest, for the many of us finding this ticket
 on Snow Leopard's release day.

 This ticket is closely related to ticket #2965 (new feature request)
 [http://hackage.haskell.org/trac/ghc/ticket/2965 GHC on OS X does not
 compile 64-bit]
 One can show one's support for this request by adding one's email to its
 cc: list.

 There is an active Haskell Cafe thread, with more detailed directions on
 the fix given here:
 [http://www.nabble.com/Snow-Leopard-Breaks-GHC-td25198347.html Snow
 Leopard Breaks GHC]

 One sees comments elsewhere, e.g. on reddit posts, to the effect of
 "aren't most OS X users just 2 core tourists on 2 GB MacBooks"? Meanwhile,
 as GHC emerges as the only credible choice for a parallel language (add a
 couple of lines of code, and it ''just works''), what I've seen makes OS X
 appear to be the only credible choice for a parallel operating system:
 [http://www.haskell.org/pipermail/glasgow-haskell-
 users/2009-April/017050.html No "last core parallel slowdown" on OS X]

 OS X self-identifies as a 64-bit operating system, yet GHC support is
 limited to 32-bits. It would be nice if there was a status somewhere
 between (closed) and (new feature request) in tone, that recognized the
 outdated state of GHC support for OS X.

Comment:

 I just verified that the patch quoted above is not sufficient to build GHC
 on Snow Leopard.  Validate dies on the first file that the stage1 compiler
 tries to compile.  (BTW, GHC does not run in 64 bit mode on SL.  It's just
 that the Apple's compiler tool chain builds 64 bit binaries by default.)

Comment (by chak):

 Just pushed
 {{{
 Thu Sep 17 14:41:21 EST 2009  Manuel M T Chakravarty
 <chak@...>
   * Fix build on Mac OS 10.6 (Snow Leopard)
   - We have -m32 as machine-dependent option for gcc for a 32 bit build
   - Like on OpenBSD, SL requires -fno-stack-protector to avoid triggering
 the
     stack smashing checks inserted by gcc by default on this platform.
 }}}
 which fixes the build on SL and also validates on Leopard.

 NB: This fixes the build.  However, the testsuite doesn't work as SL comes
 with Python 2.6.1, which apparently has a bug in on of its libraries that
 is tickled by GHC's testsuite.  The error message is
 {{{

   File "../../driver/runtests.py", line 112, in <module>

Comment:

 I don't think that the advice on the mailing list is enough to fix all of
 the issues, which is why you're seeing test failures with FFI. I'm using
 the stock 6.10.4 OSX binary release on Snow Leopard, with the shell script
 wrappers patched to add "-optc-m32 -opta-m32 -optl-m32".

 I can't get zlib to build properly, I keep getting "incompatible zlib
 version" errors. After pounding my head at it for a while, and confirming
 "yes, I'm linking to the correct zlib" and "yes, this is a 32-bit
 executable", I decided to get to the bottom of it. I built a version of
 the C zlib in debugging mode and set a breakpoint on the init function.
 It's failing here (inflate.c line 152):

 {{{
     if (version == Z_NULL || version[0] != ZLIB_VERSION[0] ||
         stream_size != (int)(sizeof(z_stream)))
         return Z_VERSION_ERROR;
 }}}

 In gdb:

 {{{
 (gdb) print stream_size
 $3 = 112
 (gdb) print sizeof(z_stream)
 $4 = 56
 }}}

 Hmm, that isn't right. Here's the relevant snippet of {{{Stream.hsc}}}:

 {{{
 c_inflateInit2 :: StreamState -> CInt -> IO CInt
 c_inflateInit2 z n =
   withCAString #{const_str ZLIB_VERSION} $ \versionStr ->
     c_inflateInit2_ z n versionStr (#{const sizeof(z_stream)} :: CInt)
 }}}

 Looks like that "sizeof" is being executed in a 64-bit context by hsc2hs;
 I haven't seen this mentioned on the mailing list but I think users also
 need to patch /usr/bin/hsc2hs to read:

 {{{
 exec
 /Library/Frameworks/GHC.framework/Versions/610/usr/lib/ghc-6.10.4/hsc2hs
 $tflag $HSC2HS_EXTRA --cflag="-m32" --lflag="-m32" ${1+"$@"} "$Iflag"
 }}}

 Does the aforementioned patch address this issue?

Comment (by duncan):

 This looks like the right explanation for the symptoms when using zlib.
 The program compiled by hsc2hs does need to be using the same environment
 as everything else.

 Manuel, can this ticket be closed now?  Does hsc2hs pass the correct flags
 to gcc when invoked from Cabal?

 No, hsc2hs doesn't get the right flags.  Specifically, what is missing is
 that if we have i386_TARGET_ARCH and darwin_TARGET_OS, we need to pass
 -m32 to the compile and link flags that hsc2hs passes to gcc.

Comment (by guest):

 It doesn't seem to allow linking with 64-bit OSX libraries like XLib (e.g.
 for xmonad). Am I right ?

 The libraries on Snow Leopard are shipped as universal binaries containing
 code for PPC, i386, and x86_64.  When a 32-bit GHC invokes the linker, it
 will automatically pick the 32-bit version of the library.
