Hi,
I have not really read through the whole thread, I apologise if this
does not apply to your problem then.
I have moved most of the PDL stuff to perlbrew which allows a fairly
system independent installation, it's berrybrew on windows, I don't own
Macs. On linux, your distribution most probably provides it, I used apt
to install the software itself. The best part about is, that system
(perl) upgrades don't break your PDL installation. This allowed me to
consistently run things cross platform with no troubles for a long time.
Run
> perlbrew install <perl version>
> perlbrew install-cpanm
> perlbrew install-patchperl||
||
||It takes a fair amount of installation time and I guess disk space,
defaults to your home.
Please consult the perlbrew docs for the exact process, this is I think
the most useful info: https://perlbrew.pl/Perlbrew-and-Friends.html.
Once you are set, use
> perlbrew switch ...
> cpanm PDL::Graphics::Simple
I guess you may need to install a few dependencies that are either
ambiguous or simply missing using cpanm from the same shell. I don't
remember if P:G:S comes with a default backend or if you need to, for
example, install gnuplot.
I hope this helps.

Hello,
would anyone with a working version mind to post some hints on how to
achieve:
cpan PDL::Graphics::Simple
pdl> use PDL::Graphics::Simple
pdl> imag (sin(rvals(200,200)+1))
on no matter on which platform but with the least number of steps?
Thanks a lot, Thomas

Hello Thomas (ngO177),
I encountered a similar problem building PDL 2.083 and 2.084 in
macOS Monterrey, to wit: getting PDL::Graphics::Simple to work, or
even to pass its build tests. Rather than repeat the odyssey I
went through here I suggest you read the write-up I did at
perlmonks that documents the build debug process:
https://www.perlmonks.org/?node_id=11153860
I posted this as open-issue #450 at PDL meta-cpan, but alas, no
one from PDL dev has, as yet, bothered to read it. In a nutshell,
you need a graphics engine on your machine and if there isn't one,
or PDL can't find it, the Alien process (since a graphics engine
is defined in PDL-speak as an alien process) will find one
appropriate to your OS on the net, download and build it for you.
Alas, for macOS Monterrey, Alien built a crippled plotting engine.
It failed to un-comment any of the three #ifdef terminal
definitions that support graphics in macOS. Thus, no terminal def
for macOS was compiled into gnuplot. The fix, for me, was to rtfm
the build docs, initialize the environment to point to my
preferred graphics engine (gnuplot, built by me with macports
rather than Alien), and enable interactive build tests. To be
fair to PDL developers, this is all documented in the PDL build
instructions and 'man gnuplot', but most of us take the ease of
building Perl modules for granted and don't bother to read them
unless something goes wrong. Alien is a brilliant idea but at
present its execution in PDL is flawed. It attempts to
transparently obtain for you an appropriate graphics engine but
fails to build it correctly. With a little hacking you can get
around this, I did, but as always, your mileage will vary. I
would very much like to hear from you after you have read the
perlmonks post and evaluated my solution in a Linux context. My
PDL in Monterrey is now working correctly, so I held off trying to
build PDL in Ubuntu, but if nothing works for you I will give it a
try.

Will Schmidt (perlboy_emeritus)

Hello,
in order to take some first steps

on Debian 12 w/ experimental repos activated, all I try, see

Any ideas?
