Using wrong libparrot.

[coke]

Large number of test failures in a vanilla 'make test' on feather.perl6.nl (the shared linux dev box.) (r39961)

Configure.pl is run with "--prefix=/home/coke/bird", no other options.

Here's the test harness output:

Looking at the last test, here's a representative failure:

#   Failed test 'C:  unlike hello world'
#   at t/perl/Parrot_Test.t line 453.
# STDOUT is:
# not ok 1 - C:  unlike hello world
#
# not:

#
# as expected
# STDERR is:

# # Exited with error code: 127

Note that we're trying to load libparrot 1.2.0, and if we check the default installation dir:

$ /usr/local/bin/parrot --version

We should additionally make sure we test multiply /installed/ parrots before the 1.4 release to insure that there is no undocumented conflict. (not just that parrots in build directories do not conflict with previously installed parrots.)

I'm pretty sure that the main build process doesn't fall prey to this problem (TT #30). This particular problem looks like a duplicate of TT #115 (though this ticket has useful specific details, so TT #115 should probably be closed as a duplicate instead.)

In any case, the t/src tests are probably due to an error in the way the sources are compiled and linked. Indeed, looking quickly at lib/Parrot/Test.pm, it seems to do two odd things: First, it puts $linkflags too early -- that likely includes -L/usr/local/lib, which is causing this problem. Second, it seems to go through great contortions to re-create the Config variable libparrot_linkflags which is supposed to be for exactly this use.

I've attached a simple patch to try to fix both problems. It is completely untested, but I think it should work. If it doesn't, I think the first attack should be to try to set libparrot_linkflags correctly over on the Configure.pl end. If that proves unworkable for some reason, then this patch should be revised. In any case, extending or embedding parrot should be easy. PConfig ought to include all the relevant variables already set up. No OS-specific contortions should be required in this part of lib/Parrot/Test.pm.

With this patch, I'm left only with the failures in TT #823 so +1 from me.

Applied in r39966, remaining issues in TT #823.
