Problems with building Perl modules after upgrade to g++ (GCC) 6.4.0

After upgrading to g++ (GCC) 6.4.0, I am being forced to
reload/rebuild a bunch of Perl modules that had been working fine.  I
had the same issue with GCC 6.3.  One module is particularly
troublesome.  I have the openssl library installed.  This is with the
64-bit Cygwin.  I attached cygcheck.out

I would roll back to GCC 5.x but that doesn't appear to be an option in Setup.

Re: Problems with building Perl modules after upgrade to g++ (GCC) 6.4.0

I now realize that Net::SSLeay and LWP::Protocol::https are both
pre-compiled modules that I can download from Cygwin.  But even after
re-installing LWP::Protocol::https, my Perl program still won't run:

Can't locate LWP/Protocol/https.pm in @INC (you may need to install
the LWP::Protocol::https module) (@INC contains:
/usr/lib/perl5/site_perl/5.24/x86_64-cygwin-threads
/usr/lib/perl5/site_perl/5.24
/usr/lib/perl5/vendor_perl/5.24/x86_64-cygwin-threads
/usr/lib/perl5/vendor_perl/5.24
/usr/lib/perl5/5.24/x86_64-cygwin-threads /usr/lib/perl5/5.24 .) at
../scripts/QRZ_daily.pl line 17.

I don't know why it's not finding the module, and what this has to with gcc.

It looks like you're using the test release of perl-5.24.  But the Perl 
modules in the Cygwin distro have been built for perl-5.22.  If you 
downgrade to perl-5.22.4-1, you should be OK.

I don't know why that would be necessary or why the gcc update has
anything to do with it.

Unless you know what you're doing and can navigate the inevitable
obstacles, do not use cpan on Cygwin.

The most likely reason is that you do not have the *-devel package for
openssl installed.

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.

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
