Certlint ASN1Validator compiling error

[Paulo Oliveira]

Windows version: Windows Server 2019 (latest updates)

Ruby version: ruby 3.0.1p64 (2021-04-05 revision 0fb782ee38) [x64-mingw32]

RubyGems version: 3.2.15

Installed Ruby with Devkit

I need to run Certlint (GitHub - certlint/certlint: X.509 certificate linter) on my Windows Server 2019. After checking documentation Certlint needs asn1validator, which instructions to compile can be found here: certlint/README at master · certlint/certlint · GitHub.

However, when I try to compile I am getting the following errors:

And also:

So, my question is how can I make it work?
