This ticket was originally filed nearly 13 years ago. There have been
no postings in more than 10 years. In my reading, Schwern ruled out
using ExtUtils::MakeMaker as a solution to the problem. After that,
discussion lapsed.
Cross-compilation is inherently difficult and does not admit of broad,
general solutions. Since the original post does not contain specific
examples, the ticket doesn't get us anywhere with respect to specific
cross-compilation problems.
I recommend we close this ticket.
Thank you very much.
