I am trying to get GHC 6.5 to compile on Mac OS X and I am not having much success. I managed to get the CVS version to build without any problems on my linux machine, and when I followed the same steps to complie on my mac I get errors.

Here are the steps I followed on my mac

autoreconf ./configure make

I am using Happy version 1.14 alex version 2.0.1

I also tried 2 different builds, one using gcc 3.3 and the other using gcc 4.0

With gcc 4.0 I get the following error:

------------------------------------------------------------------------ ==fptools== make all - --no-print-directory -r; in /Users/chrisbrown/fptools/ghc/utils/hsc2hs ------------------------------------------------------------------------ /usr/local/bin//ghc -H16m -O -i../../lib/compat -ignore-package Cabal -Rghc-timing -Wall -c Main.hs -o Main.o -ohi Main.hi /tmp/ghc7100.s:unknown:Undefined local symbol L___DISCARD__$stuc <> make[3]: *** [Main.o] Error 1 make[2]: *** [all] Error 1 make[1]: *** [all] Error 1 make: *** [build] Error 1 dhcp293e:~/fptools chrisbrown$

And with gcc 3.3 I get:

These error messages seem to be non-deterministic. I am running Mac OS X 10.4.1 with 1 gig RAM.

This seems very strange indeed - I immediately suspect something odd with your hardware. Try swapping out RAM, if you can. Strange that it only seems to affect Perl (Perl is running the mangler that generates that .s file). I suppose it's possible there could be something strange with your Perl - maybe try replacing that? If you run GHC with -keep-tmp-files, you can capture the erroneous .s file for later inspection; that might give us more clues. Cheers, Simon
