            Bug ID: 107607
           Summary: tools-src/calcpath uses unportable realpath(1)
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: modula2
          Assignee: gaius at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
  Target Milestone: ---

When trying to build the devel/modula-2 branch on Mac OS X 10.7/Darwin 11, it
failed when executing gcc/m2/tools-src/calcpath since that Darwin version
doesn't
have realpath(1) at all.  It isn't mentioned in the Autoconf docs which are a
good source for portability advice.  The possible alternative readlink -f
cannot be used either because, while the command exists, the native version
doesn't support the -f option.

I'm currently cheating by using the coreutils 9.1 version, but building that
on Darwin 11 is sort of a nightmare and seems way overkill just to run a single
script.

m2: Remove bdepend on realpath, cut and echo

I've already written a patch that removes the realpath invocation.

LGTG

I've tested it on amd64 both in tree and out of tree with and absolute and
relative paths to configure.  No extra failures.

Thanks for the patch!
