I have tried the above and too many syntactical variations, but automake
complains about all of them when I try to achieve the intention of the
above.
Respectfully,
I guess Automake is just complaining about GNU make specific
constructs ('$(replapth ...)' in this case) that would cause
other make implementations to choke. You might need to add
AUTOMAKE_OPTIONS = -Wno-portability to the Makefile(s) using
such constructs (I assume you are OK with mandating the use of
GNU make to build your package).
HTH,
Stefano

Hey Stefano,
I'd prefer to keep it portable, so I wonder if it's possible to invoke
things like realpath directly from the shell if realpath is present on
the system?

Thanks Stefano. What I ended up doing that may be helpful for others without relying on non-portable extensions to Make was the following... PATH_WORKAROUND != mktemp --suffix=.dtshd.spdif --dry-run ...to generate a path the ALSA file writer plugin can write out to which is absolute, normalized, and (should) contains no spaces. -- Kip Warner -- Senior Software Engineer OpenPGP encrypted/signed mail preferred http://www.thevertigo.com signature.asc Description: This is a digitally signed message part
