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.
