When SSLeay.dll was built, no .def file was supplied.

Ok enlighten me. .def file? I just built openssl from scratch, same problem. So what am I doing wrong. Its been a while since I've driven a compiler and code (8 years or so) so be gentle.

That's very strange. I've just downloaded the binary that ppm should have installed and the SSLeay.dll that ships with it definitely exports that symbol:

You can see quite clearly that boot_Crypt__SSLeay is there.

I can only conclude that either:
1) that's not the binary that was installed;
or
2) another different SSLeay.dll (one that doesn't export that symbol) is being found first.

You could check that 1) is not the problem by downloading the same binary as I did, extracting it to a temporary location, and copying SSLeay.dll across to your C:/Perl/site/lib/auto/Crypt/SSLeay directory. If, having done that, you still get the same error, then you will know for sure that a different SSLeay.dll is being found first.

Cheers,
Rob

So, I don't know how you installed Crypt::SSLeay for this version of Perl, but it didn't work. Maybe you have more than one version of Perl on this machine and for some reason they "both" think that C:/Perl/lib and C:/Perl/site/lib are fair game for them. In any case, you will have to resolve that situation and then reinstall Crypt::SSLeay.

Only one version of Perl on this machine I just installed it in the past 48 hours on this host. What do you see that leads you to believe there is more than one installation? I have installed and reinstalled SSLeay several times.
