The $(srcdir) value passed is often essentially useless since it may
just be '.'. It is difficult for the Makefile to produce better
values except for perhaps offsets from @abs_top_srcdir@ and
@abs_top_builddir@ substitutions. It may also be possible to play
games by passing back-ticked shell script fragments rather than
normal values in the TESTS_ENVIRONMENT specification.
Regardless, the tests themselves should not have to know their
position in the source or build tree.
If I add this sort of junk to the top of my test scripts then they
seem to pass the tests:
set -e
SRCDIR=`dirname $0`
SRCDIR=`cd $SRCDIR && pwd`
TOPSRCDIR=`cd $srcdir && pwd`
cd utilities || exit 1
MODEL_MIFF="${TOPSRCDIR}/Magick++/demo/model.miff"
.
.
.
Without the pwd's distcheck can't pass since srcdir may be passed as a
useless '.'.
Unfortunately, with hundreds of such scripts, altering the test
environment to convert to a non-recursive make is quite a penalty.
Many scripts could be one-liners if Automake can produce a
per-directory test environment.
I made a stab at converting libtool to non-recursive make last year (I
think) and had much the same problem. I think the general solution is
to move to an Autotest based testsuite, where the input files are
generated by the test rather than searched for in the source tree.
Maybe you can emulate that behaviour by making your test input into
here documents in the test scripts, without a whole scale move to
Autotest?
Cheers,
Gary.
