This is more an open discussion and a conclusion than a real question, hoping it can help someone sometime.
I was looking on how to make Perl module on an Internet disconnected server (otherwise the answer is quite simple: use cpan
), so the only option I have is to manually compile the modules downloaded from the Internet (CPAN or others) directly on the server.
The problem was that, on a standard Windows server, there is no compiler. So how do I make the modules?
