I have been building Perl packages for years without problems. I use WWW::Mechanize in several programs, and it has a lot of pre-requisites. >> SSLeay.xs:163:25: fatal error: openssl/err.h: No such file or directory >> #include <openssl/err.h> > > The most likely reason is that you do not have the *-devel package for > openssl installed. Missed that, thanks! I don't know why Cygwin "upgraded" me from Perl 5.22 to Perl 5.24. I am building a new Cygwin installation from scratch (via setup) and it has Perl 5.22 (as expected) and gcc 6.4. I seem to remember this problem happening in the not-too-distant past when gcc 6.x was experimental, so I probably picked up the experimantal Perl 5.24 as well. I tried to roll back Perl from 5.24 -> 5.22 in my existing Cygwin (non-experimental) installation but "perl --version" still returned version 5.24 Anyway, I'll have a clean installation soon, I hope. - Jim -- Jim Reisert AD1C, <jjreis...@alum.mit.edu>, http://www.ad1c.us -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
