Can I shut the OpenSolaris shell up ??

[Dave]

I've built auotconf on OpenSolaris 06/2009, with no problems, but it fails 252
tests in the testsuite, which is about 50% of them. I reported this to the
auotconf mailing list. This is the response from Ralf Wildenhues, one of the
autoconf developers, when I asked what was wrong.

Yes: your shell is very chatty:

and the Autoconf testsuite tries to be strict about warning output.

It's pretty ironic that a Solaris shell should warn about `...`, with
Autoconf using that construct mostly because shells like Solaris <=10
10) /bin/sh does not cope with $(...). Oh well. Can the shell be told
to not output these warnings somehow? I took a quick look at
<http://dlc.sun.com/osol/man/downloads/current/> but couldn't find a
switch or environment variable to do so.

Thanks for the report,
Ralf

Does anyone know how I might answer his question and stop the shell showing all
the warnings?

Why don't you use the SUNWaconf package for OpenSolaris?

pkg search autoconf
pkg install SUNWaconf

It is a "ksh93 -n" feature (/bin/sh is ksh93 in OpenSolaris). I don't
think you can turn it off. Can the tests use a different shell if it
doesn't like the ksh93 warnings?
