Here is my attempt to getting PDL to work in Ubuntu similar to an
already functional version in Arch, see logs below my personal
instructions.
Has anyone encountered similar issues or knows a remedy?
Thanks a lot, Thomas

Hi Thomas,
You will want to install Term::ReadKey and probably
Term::ReadLine::Gnu to have a nicer, more interactive perldl. I
don’t use pdl2 myself, but it did tell you what it needs to run if
you want to use it.
Also, Alien::Gnuplot only installs (or checks for) actual gnuplot.
If you want the PDL interface to it, which PDL::Graphics::Simple
wraps around, you need to install PDL::Graphics::Gnuplot. This
would solve the thing PDL::Graphics::Simple was telling you:
“Sorry, all known plotting engines failed. Install one and try
again.” Please read
https://metacpan.org/pod/PDL::Graphics::Simple#SUPPORTED-GRAPHICS-ENGINES

Hello Ed,
as I understand, there a different options to get First Steps from
the PDL book to work. I have adopted the approach using
perlbrewand cpanmas they seem the most stable.
Please find below the sequence of commands issued and the final
error messages under Ubuntu. I used the same approach on three
different Linux distributions (Debian, Ubuntu, Arch) with the same
result.
Is there any chance to reproduce the problem and look into it?
Thanks a lot, Thomas

Hello Ingo,
much appreciate! Just to ask which perl version is most likely
to run the commands from the First Step PDL Book?
@anyone: which perl version is known to work for that purpose?
Thanks a lot, Thomas

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.
Ingo

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.
Regards,
Will Schmidt (perlboy_emeritus)
