Hi Hernán,
Thank you for the feedback! Any further issues or concerns you see, please do 
raise them. While PDL is pretty good now (at least so I believe), it can always 
be better, and the best way for that to happen is for people to question 
things. So please keep doing so, either on here, or by opening a GitHub issue, 
or whatever other means you feel suitable :-)

Best regards,
Ed

Hi Hernán,

Great to hear your local issue is sorted – thank you to you and Shawn!

PDL absolutely will build without Alien::proj. Problems will only arise if it 
is installed but broken. You can prove this by making a new Perl installation 
(“perlbrew” is my recommended tool) with no Alien::proj (but with other actual 
needed deps like File::Map) then install PDL on it. This is also tested on 
every single commit of PDL which gets built and tested in our continuous 
integration (CI) in (among many, many other environments) a container on CentOS 
with minimal deps.

perldl.conf as a mechanism is not a suitable vehicle for this, nor really for 
anything else. The whole Alien concept in Perl was originally invented to solve 
this class of problems, for PDL. We are sticking with it until a convincing 
case is made for something better.

Dear all,

Just to report that thanks to a good collaboration with Shawn we were able to 
track the problem to an empty "PKG_CONFIG_PATH" in my system. After adding the 
proper paths now Alien::proj and PDL both compile fast, well and smoothly.

It also seems that PDL will not build without Alien::proj. Then the question

I use openSUSE Tumbleweed (rolling release). I have used Linux exclusively

Hi Luis,

The current plan isn’t to make changes to the structure of PDL in any case, 
since (after some painful fixes to the Fortran stuff a couple of months ago for 
32-bit systems) there is no maintenance effort for the Fortran stuff. 
Regardless, it’s reassuring that you’d be content with such a shift! (After 
all, this “PDL” thing exists for the benefit of the users)

It would be really helpful to know if you found any of those other options were 
useful replacements for part or all of what Minuit does (I’m not qualified 
right now to have an opinion), simply so I (or someone!) could add a note to 
the PDL::Minuit docs. Please let me know if you do make any such finding :-)

Ref that PR, I understand how things go! Among other things, I still want to 
look over Ingo’s OpenCV stuff, and PDL::Stats’s anova stuff is still somewhat 
broken (which I revisited last year trying to make a nice visual demo for 
PDL::Stats). Anyone who knows more about statistics than me who wants to help 
or even offer guidance on that or the OpenCV stuff, please speak up!

Best regards,
Ed

Hello Hernan,

If you have issues installing Alien::proj then could you please file a bug 
report?  https://github.com/shawnlaffan/perl-alien-proj

If you have proj installed with its headers then Alien::proj will run a system 
install.  This will just use your existing installation.  If it cannot find the 
headers then it will run a share install, which means it builds the system from 
source code.

You have not said what operating system you are using but as an example the 
libproj-dev package is needed on ubuntu to trigger a system install.

WRT Ed's comment about GDAL bindings, Geo::GDAL::FFI provides these for perl 
and has methods to convert rasters to and from PDL ndarrays.

which I suspect you normally do using a tool that
doesn’t show you these messages) is only warning you that it
can’t build Proj4 or HDF4. It will carry on and build everything
else that it can, as hopefully you’re seeing. You’re saying core
and GSL work, which wouldn’t be true if everything else hadn’t
built? You say “FFTW”, but there is only an “FFT” in PDL.
https://metacpan.org/pod/PDL::FFTW3 is an external distribution,
and is recommended over PDL::FFT.

The build system was restructured last year so that the tests for
those things now live within their submodule directories. That is
the idiomatic way (in ExtUtils::MakeMaker-using distributions) of
doing these things, and allowed deleting of lots of unnecessary
“protection” code, since those tests aren’t tried if the
submodule doesn’t build (which makes sense if you think about it).

Yes, PDL needs the Alien::* stuff for this. That allows
outsourcing of things like building (or even just finding, which
is surprisingly fiddly) a PROJ installation to other code. If you
don’t have the Alien modules installed, PDL works fine but
without the submodules those would have needed. This has been how
PDL has operated (not building submodules that don’t have needed
bits) since at least the year 2014. I don’t understand your point
about “whimsical” or Proj v9, since PDL has supported PROJ v6+
since version 2.064, over 3 months ago. If you have an
OS-packaged PROJ v6 or newer, then install Alien::proj, which PDL
now looks for (note, not Alien::Proj4), it will see the installed
version and not build its own. If you then reinstall PDL, it will
see that and build the PDL::Transform::Proj4 stuff (the name
“Proj4” is unimportant, it’s updated to v6+ so don’t worry).

There is certainly some demand for PDL GDAL support. The sensible
way would be to make a separate distribution for it. I wouldn’t
be surprised if it only needed similar code to current
PDL::GIS::Proj, with the equivalent of wrapping a forward and
backward transform with parameters. If you’d like to create such
a thing, we (the PDL porters) can help! Join the IRC channel
and/or email on here :-)

The Fortran stuff is only warnings. You will note the submodules
still built, passed tests and installed. The Fortran code in
those submodules (Minuit and Slatec) are written in Fortran 77,
and are dramatically obsolete. We may or may not remove them into
separate distributions, since I doubt anyone uses them.
Nevertheless, they still work. Minuit 2 (not yet supported by
PDL) is written in C++. Slatec is obsolete and replaced by
LAPACK, for which use https://metacpan.org/pod/PDL::LinearAlgebra.

Please open an issue on
https://github.com/Perl-GPU/OpenGL-GLUT/issues describing the
problem you’re having with GLUT to help us fix it. My plan is to
roll OpenGL::GLUT back into a single OpenGL distribution to ease
installation/use.

Best regards,

Ed

Hi all

Thanks Ed and others for the great job you do maintaining and
developing PDL. Hats off!

Today I got news that 2.078 was available so I promptly went on
CPAN and hit upgrade. But for the first time in *many* years PDL
did not just build smoothly right away.

Upon investigation I see that PDL complains about Proj4 and HDF4
lacking when trying to build PDL::Transform. Problem is I cannot
find anywhere in perdl.conf where I can tell PDL not to care
about this and not run the t/gis_proj.t and t/proj_transform.t
tests. If I remember correctly that possibility existed years
ago. Can we still build PDL without using Proj? Perhaps using
--force? But that is not very elegant ...

A related question is: does PDL really need Alien::* for this
stuff? I would prefer not to mess with that because these
packages install lots of stuff I do not need nor want in my
system. I actually work everyday with geoinformatics and normally
have the latest gdal/ogr and proj. If PDL needs proj I believe it
would be much better to have PDL rely on those rather than some
whimsical Alien::* installing ancient proj4 versions (proj is v.
9 now).

Less serious stuff:
- Glut fails to install at the end but this has been the case for
many months and not been a problem
- there are a lot of FORTRAN warnings (see exerpt below), perhaps
some deprecated syntax that the latest gfortran (11.2.1 20220316)
does not like.

Good things:
- Core, FFTW, GSL build smoothly as usual.

I do... :(

What would be the recommended modules, alternative to minuit, to
optimize multiparameter functions using the current PDL?

Re: [Pdl-general] PDL 2.078

2022-04-11 Thread Ed .
Hi Hernán!

PDL’s build (which I suspect you normally do using a tool that doesn’t show you 
these messages) is only warning you that it can’t build Proj4 or HDF4. It will 
carry on and build everything else that it can, as hopefully you’re seeing. 
You’re saying core and GSL work, which wouldn’t be true if everything else 
hadn’t built? You say “FFTW”, but there is only an “FFT” in PDL. 
https://metacpan.org/pod/PDL::FFTW3 is an external distribution, and is 
recommended over PDL::FFT.

The build system was restructured last year so that the tests for those things 
now live within their submodule directories. That is the idiomatic way (in 
ExtUtils::MakeMaker-using distributions) of doing these things, and allowed 
deleting of lots of unnecessary “protection” code, since those tests aren’t 
tried if the submodule doesn’t build (which makes sense if you think about it).

Yes, PDL needs the Alien::* stuff for this. That allows outsourcing of things 
like building (or even just finding, which is surprisingly fiddly) a PROJ 
installation to other code. If you don’t have the Alien modules installed, PDL 
works fine but without the submodules those would have needed. This has been 
how PDL has operated (not building submodules that don’t have needed bits) 
since at least the year 2014. I don’t understand your point about “whimsical” 
or Proj v9, since PDL has supported PROJ v6+ since version 2.064, over 3 months 
ago. If you have an OS-packaged PROJ v6 or newer, then install Alien::proj, 
which PDL now looks for (note, not Alien::Proj4), it will see the installed 
version and not build its own. If you then reinstall PDL, it will see that and 
build the PDL::Transform::Proj4 stuff (the name “Proj4” is unimportant, it’s 
updated to v6+ so don’t worry).

There is certainly some demand for PDL GDAL support. The sensible way would be 
to make a separate distribution for it. I wouldn’t be surprised if it only

a forward and backward transform with parameters. If you’d like to create such

[Pdl-general] PDL 2.078 released

2022-04-10 Thread Ed .
Dear PDL folks,

PDL 2.078 has just been released. Notable changes since 2.077:


  *   TriD::GL now more resilient and exceptions don't leave GL broken
  *   Bugfixes including to NiceSlice
  *   “demo 3d” now shows off a 3D Earth (with accurate shading), and also a 3D 
molecule-like graph evolving over time
  *   The “pdl” struct now has room for a single value (or if not complex long 
double, several values of smaller datatypes), avoiding extra memory-management 
for small ndarrays – but you don’t need to recompile installed modules

Future plans, in something like intended order:

  *   fix more open GitHub issues
  *   “loop fusion” techniques to maximise locality of computation, minimising 
data’s trips through the “straw” between CPU and main RAM
  *   finish the independent C interface for making PDL usable from e.g. Python
  *   use OpenCL or other means to also utilise GPUs if available

The IRC channel (#pdl on irc.perl.org) is a great virtual place to come and ask 
questions, or just watch the GitHub messages flow by.

As usual, please give the new release a try and report problems.

Best regards,
Ed
