Bootstrapping for Leopard

I'm trying toupdate the Portfile so that ghc-6.8.2 can be built using MacPorts
(handy for installing other ghc-dependent material from MacPorts like
gtk2hs). The problem seems to be that the available bootstrap binary
causes a segfault on Leopard (below are the steps I took in my attempt to
build ghc with this bootstrap binary).
Using Manuel Chakravarty's binary distribution of ghc-6.8.1-i386-apple-darwin
building ghc-6.8.2 works fine. It seemed to me that the easiest way to fix
the bootstrap problem is to boot from C as described on the wiki
(http://hackage.haskell.org/trac/ghc/wiki/Building/Porting). Two things were
Making the hc-file-bundle target failed, because not all rts/*.cmm had
rts/*.hc counterparts after the build. The make fails because of this
fragment from the Makefile (part of the hc-file-bundle target, starting from
for f in `$(FIND) ghc-$(ProjectVersion)/compiler
ghc-$(ProjectVersion)/rts -name "*.cmm" -follow -print` ""; do \
if test "x$$f" !=3D "x"; then \
echo `echo "$$f" | sed 's/cmm$$/hc/g' ` >> hc-files-to-go ; \
This adds some non-existing .hc files to the hc-files-to-go list that tar will
not find, later on, causing an error. I just added a test to see whether the
file exists. If it does not, I call make for that .hc file explicitly, which
solves the problem for most files. The files that don't have a make target, I
simply omitted from the hc-files-to-go. I haven't been able to test the
severity of this, because of the second problem.
sh -e ./distrib/hc-build --prefix=3D$HOME/src/testbuild [--enable-hc-boot
As a minor bug wrt. the wiki page, the hc-build is not executable by default.
The more serious problem seems to be that the cold-boot option of configure
is broken, because it ends in the error:
checking for ld... /usr/bin/ld
checking for path to top of build tree... ./configure: line 2651: -v0: command
./configure: line 2655: utils/pwd/pwd: No such file or directory
configure: error: cannot determine current directory
Upon inspection of the configure script, I found out that line 2651 uses the
variable designating the ghc compiler.
Are these bugs or am I messing things up?
