Install Perl 32-bit

Asked by Jeffery Ashmore

I currently have Perl 5, version 22, subversion 1 64-bit installed on my Ubuntu 16.04 server. I need to install the 32-bit version in order to install an application. How do I keep both 64-bit and 32-bit Perl installed and how to I enable the 32-bit only?

Do you need the 32bit variant of the perl executable, or just the 32bit libraries?

You might try with the library first:
sudo apt-get install libperl5.22:i386

and only if that is not sufficient, you could continue with the 32bit variant of other perl packages (if that is possible at all).

(disclaimer: have never tried that myself)

Manfred, thank you for your speedy reply. Do you know the name of the 32bit variant of the other perl packages or where I do go to view this is information?

You get the 32bit variant if you add ":i386" to the package name.

Manfred, again thanks. I was already aware of the adding ":i386" to the package name. What I do not know are the names of the Perl 32-bit packages. Can you point me in the right direction to obtain the Perl package names?

I suggest that you run the command

dpkg -l | grep perl

This will list all packages with the string "perl" in its name or description, than you currently have installed.
This can serve as a candidate list for the 32bit packages.

(Warning: there is a known bug #1574351 that prevents installing different architecture versions of some perl packages without additional tricks.)

Can you help with this problem?
