I'm trying to build unregistered 6.8.2 on NetBSD Alpha 2.1.0_STABLE -- I have the following problem which seems to be same as this one - http://hackage.haskell.org/trac/ghc/ticket/1860
No, I think it's another problem.
$ ./configure --enable-hc-boot --enable-hc-boot-unregistered [...] checking for ld... /usr/bin/ld checking for path to top of build tree... ./configure[3201]: -v0: not found ./configure[3203]: utils/pwd/pwd: not found configure: error: cannot determine current directory
What happens here is that configure tries to compile some utility program (utils/pwd/pwd) using an existing ghc, which of course is impossible when you're porting ghc a platform not already running ghc. Similar problems are located in libraries and the Cabal-generated GNUmakefiles. For the utils/pwd/pwd problem, I really don't understand why that thing is required at all, since it does little more than get the pwd and add some slash or backslash escaping/quadrupling depending on the argument passed to it. You may try the patch below (and don't forget to re-run autoconf). Note that this is the quick hack I did for OpenBSD. If the forward slash hack of util/pwd is really required (for Windows builds?), something like hardtop=`pwd | tr '\\' /` would be more appropriate. And the other sanity checks I deleted may be necessary in some cases, too, but I really don't see the point in them. Ciao, Kili ps: IMHO, libaries/ifBuildable.hs should die a horrible death, too. It can replaced with a few lines of shell commands.. --- aclocal.m4.orig Mon Dec 10 19:11:31 2007 +++ aclocal.m4 Fri Jan 4 13:58:49 2008 @@ -1098,28 +1098,7 @@ AC_REQUIRE([AC_PROG_CC]) AC_DEFUN([FP_FIND_ROOT],[ AC_MSG_CHECKING(for path to top of build tree) -dnl This would be -dnl make -C utils/pwd clean && make -C utils/pwd -dnl except we don't want to have to know what make is called.
