Hi Erasmus,
Not sure what is going on - I never use exec if I can avoid it, but the
way you have written it is in a form that I do not usually trust the
shell to work with.
If you pass a list instead of a string you are usually on safer ground,
and that works whether you put use PDL or not:
use PDL;
my @cmd =("echo", "hello");
exec @cmd or die "Could not exec (" . $? . ", " . $! . ")\n";
Not really an answer, but return values & operation of system & exec is
mildly black magic to me and I find that as long as I pass an array
rather than a string to either I save myself a significant amount of
headache!
Cheers,
J.

I've run into an odd problem that seems to involve PDL, I was hoping
someone on the list could give me a hand.
this script:
#!/usr/bin/perl -w
my $cmd ="echo hello";
exec $cmd or die "Could not exec (" . $? . ", " . $! . ")\n";
works as expected (prints hello), but if I insert:
use PDL;
after the first line, I get the following error:
Could not exec (0, Illegal seek)
This happens on both x86_64 and i386, and with PDL version 2.4.3 and
2.3.4, perl 5.8.
Any thoughts as to what might cause this?
Thanks,
eo
