Installing Perl After A Wee Break

Saturday, 23 October 2021

(‘Wee break’ as in a short period of time (Scottish), not a ‘wee break’ like in televised snooker, tennis, etc).

Context

In October 2021 I was setting up the x220 with a new environment (KDE, Arch, etc) [UPDATE July 2022: KDE, honestly??]. I wanted Perl, so this is what I did.

I also wanted to run my on-add_scheduled_work_task.pl script for adding lines to the remote REMIND instance in taskwarrior. Additional CPAN modules needed for this to work:

• JSON
• DateTime
• DateTime-Format-ISO8601
• Net::OpenSSH

Installation steps

• Install perlbrew. Follow the instructions to install it.
• perlbrew install perl-5-34.0. This can take a WHILE so tail -f the log to watch the fun. I got a test failed when I did this, but the docs (and the console message) said that I could just run make to get it to install properly. This works.
• perlbrew switch perl-5.34.0
• Done. But then we want to install stuff from CPAN. Like JSON.
• Install cpanm using perlbrew: perlbrew install-cpanm.
• Then I wanted JSON so I did cpanm JSON. Because we installed cpanm using perlbrew it went into the right place.

This is pretty much it.
