They all have passing builds, for example XML::XPath.	[reply]

You have to install the modules, but you can use them on Linux. If you don't know how to install the modules or if you are using the Perl that comes with your system, most likely your system administrator can install the modules from the system package manager. This is the recommended way of installing modules in that situation. If you manage the Perl installation yourself (using App::perlbrew for example), then you simply install the modules using `cpan XML::CanonicalizeXML XML::XPath XML::XPath::XMLParser Crypt::Open +SSL::RSA` [download] Most likely you still need your system administrator to install the appropriate external libraries like `libxml-dev` etc.	[reply] [d/l] [select]

They all have passing builds and can be installed without issue, so you can use them.	[reply]

I have `XML::XPath` and `XML::XPath::XMLParser` installed on my Raspberry PI. `uname` identifies the OS as `armv7l GNU/Linux`. I do not use the other two modules. Now, I run a custom-built Perl and installed these using the `CPAN` client. If you are using the system Perl, you will either have to figure out which OS packages to install (if they are in fact available), or figure out how to make a `local::lib` installation. When I tried `XML::CanonicalizeXML`, it failed for a missing library. This does not mean it can not be done, it just means I need to figure out what else needs to be installed to support it. `Crypt::OpenSSL::RSA` pulled in a few other modules, but tested successfully on my Raspberry PI, meaning that it could be installed and used. Summary of my personal experience: XML::CanonicalizeXML - No relevant experience; XML::XPath - Yes; XML::XPath::XMLParser - Yes; Crypt::OpenSSL::RSA - Almost certainly yes. Note that `XML::XPath::XMLParser` is part of the `XML-XPath` distribution. If you can get `XML::XPath`, you should get `XML::XPath::XMLParser` along with it.	[reply] [d/l] [select]

Ok, all seems to work here on my Linux distro Xubuntu 20.04: XML::CanonicalizeXML `sudo apt install libxml2-dev cpan XML::CanonicalizeXML` [download] XML::XPath (this also installs XML::XPath::XMLParser i think) `cpan XML::XPath` [download] Crypt::OpenSSL::RSA `cpan Crypt::OpenSSL::RSA` [download] There may be additional dependencies/libraries you have to install in your Linux distro. I've tested this on my office dev machine, on which i already have a huge amount of stuff installed. `perl -e 'use Crypt::Digest::SHA256 qw[sha256_hex]; print substr(sha256_hex("the Answer To Life, The Universe And Everything"), 6, 2), "\n";'`	[reply] [d/l] [select]

TLDR; without knowing more, I say your chances of modules working across OSes with `perl` are HIGH. It's rather rare that you have a module that will not work with the version of `perl` at your disposal; this is one of the great things about `perl`. Where things get tricky are modules that depend on compiled libraries that are generally shipped on modern BSD/Linux that tend to be security related and thus are updated frequently, like OpenSSL.
