Dear All / Ed,
as mentioned before, it is possible to get a smooth installation of PDL
using (Perl 5.38, PDL 2.084) under Arch - in fact EndeavourOS - by the
commands below. perlbrew is not used as I have not seen a clean install
e.g. under Ubuntu which is still on perl 5.36:
yay cpanminus
sudo cpanm Term::ReadKey
sudo cpanm Term::ReadLine::Gnu
sudo cpanm Alien::Gnuplot # first
sudo cpanm PDL::Graphics::Gnuplot # second
sudo cpanm PDL::Graphics::Simple # third, pops up
However, *Alien::FreeImage* throws an error in a next step. Would any
developer mind to fix it:
sudo cpanm Alien::FreeImage # first
(used by: sudo cpanm PDL::IO::Image # second)
...
