Please just try with the latest (Perl 5.38, PDL 2.084), and report any problems?

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 On Thu, Aug 31, 2023 at 11:00 AM Ingo Schmid <ingo...@gmx.at<mailto:ingo...@gmx.at>> wrote: 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.

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.
