Hi Hernan: Sorry, I'm coming to this late. Which OS does this occur for?
I'd be happy to check this out if this happens for Linux. It sounds like
this is not a problem in PDL::NetCDF proper, but it is likely fixable in
the PDL::NetCDF XS code.
Regards,
Doug Hunt

Thanks again Rob for your help and interest!
I added the line you suggested to DynaLoader.pm (I guess you meant lines 212
and 213). Below is the output of 'make
test'. In the interim I realized that NetCDF has a new verion: 4.3, and
updated it. The problem persists though.
I am very busy this week so I will probably not have time to investigate this
further. I will report back when I find
something. Thanks for your help.

Hi Hernan,
Well ... it was never going to actually be a solution anyway. We would still
want to find out why the behaviour
was occurring :-)
I’ve just checked, and I’m running the same version of netcdf as you are
(4.2.1.1). And PDL::NetCDF built fine
for me (on MS Windows).
It’s probably not a good idea to be messing with the contents of DynaLoader.pm,
but that’s exactly what I’d do if
I was getting that error.
Line 122 of DynaLoader.pm is currently a blank line. I would change it to:
warn “\n\$xs: $xs\n”;
If it’s not a coderef, let’s try and find out what the hell it is !
Be aware that the error message could be bogus. Just a few lines before line
123 in DynaLoader.pm we find the
following comments:
# Many dynamic extension loading problems will appear to come from
# this section of code: XYZ failed at line 123 of DynaLoader.pm.
# Often these errors are actually occurring in the initialisation
# C code of the extension XS file. Perl reports the error as being
# in this perl code simply because this was the last perl code
# it executed.
However, I think this one might just turn out to be legitimate.
Cheers,
Rob

Rob, thanks for the answer and the suggested solution.

I repeatedly get the following error during test:
Error: Not a CODE reference at
/usr/lib/perl5/5.16.2/i586-linux-thread-multi/DynaLoader.pm line
213.
Try running the test script as:
perl -Mblib t/scriptname.t
DynaLoader.pm line 213 (perl-5.16.0) was throwing up a warning for me in a test
suite I was running just
yesterday. When I ran the particular test file as 'perl -Mblib t/script.t' the
warning went away.
I'm wondering whether the same approach will make your error go away.
Cheers,
Rob
