Hi Chris: Yeah, that breaks it.
the $pp_ptr_type needs to be 'longlong' after the PDL data type. Also,
I64 is not defined on my (Linux) system.
This is what I can get working:
my $ptrsize = $Config{'ptrsize'};
my $int_ptr_type = ($ptrsize == 4) ? 'I32' : 'long'; # pointer type in C
code
my $pp_ptr_type = ($ptrsize == 4) ? 'int' : 'longlong'; # PDL data type in
pp_def 'Pars'
I don't see any problem with leaving it like this.

Doug

Hi Doug and Derek-
I just pushed a slight modification of the detection of ptrsize
et. al. in plplot.pd. It uses the explicit values from Config which
should be more robust. Would you mind confirming that I did
not break anything?
Thanks much,
Chris

Hi Derek: Nice meeting you this morning.
I've put in a change to the PDL git that seems to fix the problem and works
both on Linux and Mac. It was simple. The pp_def for plAllocGrid and
plAlloc2dGrid passed out a 64 bit pointer using a 32 bit PDL 'int' value:
(in plplot.pd)
pp_def ('plAllocGrid',
NoPthread => 1,
Pars => "double xg(nx); double yg(ny); int [o] grid()",
I just changed this to:
pp_def ('plAllocGrid',
NoPthread => 1,
Pars => "double xg(nx); double yg(ny); $pp_ptr_type [o] grid()",
where $pp_ptr_type is either 'int' (for 32 bit systems) or 'longlong' for 64
bit systems.
Let me know if you have any more troubles on your Mac after pulling the
latest changes from PDL git.

Doug

Back when this was bothering me I think I had PLplot 5.9.6 (or 7)
installed. I'll get 5.9.9 installed and the latest PDL git built against
it--I have just been using whatever P::G::P is in the PDL source tree, which
looks right now to be 0.61. None of the PLplot library examples fail, just
the PDL bindings.
Does Thursday morning work? I have a lunch appointment but hopefully we
will be done before then! I'm coming from Broomfield, I'll take the bus to
Table Mesa and then the UCAR shuttle from there. I'll shoot for the 9:13
shuttle that should have me to the FL complex around 9:30. If for some
reason I miss that then I'll just bike up, it's easier than waiting for the
shuttle and Thursday looks to be a nice day for a ride. I'm assuming
there's a receptionist at the entrance like at HAO so they could direct me
your way?
cheers,
Derek

Hi Derek: I have not looked into this bug since (until recently) I did
not have a Mac. If you've got a laptop that can duplicate the problem,
perhaps you could come to my office and we could take a look at it.
I've done a fair amount of debugging in the plplot library and just
refactored the PDL::Graphics::PLplot interface so I'm still fairly
familiar with the code and might be able to help.
Have you got the plplot library source installed and compiled manually?
It will probably come down to putting print statements in plplot--it's good
to have a PDL version working that uses a locally compiled version of plplot
so you can poke around both in PDL::Graphics::PLplot and in plplot itself.
What versions of PDL, PDL::Graphics::PLplot and plplot are you using?
I'm in the new 'FLA' building at UCAR Foothills lab--3375 Mitchell
Lane--the old curving Wild Oats building. What time would be good
for you to meet?

Hi Doug,
Since the PDL bug "PLplot segfaults on plshades call on OS X" was
reported by me, but I've been unable to figure out just what is screwy, and
since you are the current maintainer of PDL::Graphics::PLplot and probably
know more about the inner PLplot workings than I do, and since that bug has
a severity of 9, and since we both work in Boulder, would you be interested
in getting together sometime maybe before Thanksgiving and trying to hammer
that out? I can easily get to UCAR's Foothills lab by bike from SwRI if I
know to bring the bike with me, or I can get to the Mesa lab first thing in
the morning some day via the UCAR shuttle.
cheers,
Derek
