OpenSSL. This build instructions include Perl https://github.com/openssl/openssl/blob/master/NOTES-WINDOWS.md#quick-start It would be great to have an update to OpenSLL docs that describe how to build using Arm64 Perl.

NASM https://www.nasm.us/   is also listed as a dependency for OpenSSL. There are no Arm build instructions (I'm guessing NASM doesnt make sense to port for Arm). I have a connection to Simon Tatham (NASM founder) so can ask there if it helps.

OpenSSL support in UWP apps for WoA seems to have some issues: https://github.com/openssl/openssl/pull/18311 Can we add this to the backlog?

Added to backlog


ARM64EC Perl

Perl distributions uses GCC which makes it bit harder to use ARM64EC. Clang ARM64EC could help.

Continue with native Perl support.



A high priority. Few patches in flight - closer to done but need help with CI/CD etc.

Conda-forge priority
