Hi,

when i try to install the Graph CPAN module, I get failures in a lot
of its tests.
All failure are in the Heap module, file elem.pm line 31..

any ideas ?

thanks...

Here is the install log:

Hi,

when i try to install the Graph CPAN module, I get failures in a lot
of its tests.
All failure are in the Heap module, file elem.pm line 31..

any ideas ?

I noticed at http://search.cpan.org/~jhi/Graph-0.81/ that 6 cpan testers
report failures. I tried to get to
http://cpantesters.perl.org/show/Graph.html#Graph-0.81 to see if any of them
had experienced the same problem as you - but cpantesters.perl.org seems to
be down.

Which version of Heap are you running (and what does line 31 contain) ? If
it's not the latest (version 0.80), maybe you should update Heap and see if
that fixes the problem.

If that does fix the problem, then you should file a bug report (at
http://rt.cpan.org/Public/Dist/Display.html?Name=Graph ) for the Graph
module, as the Graph module's Makefile.PL specifies that *any* version of
Heap will suffice.

Hmmm ... on second thoughts (since Heap-0.80 is more recent than Graph-0.81)
it may be that you need to *downgrade* Heap to an earlier version (if you're
already running Heap-0.80).

Cheers,
Rob

Which version of Heap are you running

I am running the latest, version 0.80

this is line 31 of Elem.pm:

L30: sub heap {
L31: @_ > 1 ? ($_[0][1] = $_[1]) : $_[0][1];
L32: }

Hmmm ... on second thoughts (since Heap-0.80 is more recent than Graph-0.81)
it may be that you need to *downgrade* Heap to an earlier version (if you're
already running Heap-0.80).

Is there a way to do it from the "perl -MCPAN -e shell" command line ?

(I am using cpan shell v1.9102)

Thanks,
donuvi

I would think there is, but as I don't use that method, I don't know

(If necessary you could install the module manually - ie by downloading the
source, extracting it to some location, cd'ing to that location and running
'perl Makefile.PL', 'make test', and 'make install').

There's already a bug report about this at
http://rt.cpan.org/Public/Dist/Display.html?Name=Graph - so I'm fairly
confident that installing an earlier version of Heap will fix your problem.

Cheers,
Rob
