Hi,

At least in connection with the Automake running in silent mode, the
check-DEJAGNU target should produce no noise in the output. It
probably makes sense to hide all the shell logic behind "@". This also
makes it easier to detect actual errors/warnings generated by running
the target.

Thanks,

Marc

Hi Marc,

    At least in connection with the Automake running in silent mode, the
    check-DEJAGNU target should produce no noise in the output. 

Thanks for the message. Sounds sensible to me, for silent mode. Do you
have a sample Makefile.am/configure.ac?  It would help me not to have to
construct them from scratch. --thanks, karl.

Sure. Here is a tree for a minimal project (see also the attached archive):

# ./configure.ac
AC_INIT([myproject], [0.1], [bug <at> example.com])
AM_INIT_AUTOMAKE([foreign dejagnu])
AC_CONFIG_FILES(Makefile)
AC_OUTPUT
###

# ./Makefile.am
TESTS = ok

ok:
    $(AM_V_GEN)echo "#!/bin/sh" >$@
    @chmod a+x $@

CLEANFILES = ok

EXTRA_DIST = testsuite/config/unix.exp testsuite/lib/myproject.exp
testsuite/myproject.tests/myproject.exp
###

# ./testsuite/myproject.tests/myproject.exp
pass "trivial test"
###

# ./testsuite/config/unix.exp
# empty file
###

# ./testsuite/lib/myproject.exp
# empty file
###

You should then be able to run:
$ autoreconf -i
$ ./configure [--enable-silent]
$ make check-DEJAGNU
$ make check-TESTS

As you see, I added two test cases, one using the Dejagnu test driver
(that produces the noise) and one that uses the modern Automake
parallel test driver (which does not produce any noise, regardless of
the setting of the silent flag).

I hope you find this helpful.

Thanks,

Marc

Thanks much, Marc. That's very helpful. Will look into it as soon as I
have a chance (if no one else gets there earlier). --all the best, karl.
