has anyone investigated this issue?

Yes, this is a repeat of jnthn/p6-io-socket-async-ssl/#34. Unfortunately, this is going to become more common, since libssl1.0 has now been removed from the latest KUbuntu. Here's the workaround:

• Download libssl1.0 from here
• Install it via sudo dpkg -i libssl1.0.0_1.0.2n-1ubuntu5.3_amd64.deb
• Download libssl1.0-dev from here
• Install if via sudo dpkg -i --force-all http://ftp.br.debian.org/debian/pool/main/o/openssl1.0/libssl1.0-dev_1.0.2r-1~deb9u1_amd64.deb
• You will then have to handle the symbolic link, manually: cd /usr/lib/x86_64-linux-gnu; sudo ln -sf libssl.so.1.0.0 libssl.so

You should now be able to install this module without errors.

OpenSSL 1.1.1 is quite common in the newest Linux distributions. I'm getting painted into a corner due to this issue in some cases: RHEL 8, CentOS 8, Oracle Linux 8, Fedora 31, etc.

It won't be realistic to down-rev OpenSSL in our case, so I hope that work will continue to overcome this issue.

Indeed. The libssl1.0-dev package has even been removed from Ubuntu 19.10. Seems safer to require the newer OpenSSL symbols than the older ones at this point.

Is @sergot active?

Unfortunately I'm not that active anymore @Xliff , will try to find some time this week.

Just saw this on fedora 32, OpenSSL 1.1.1g FIPS, BUT...

If I clone the repo and zef install ., it installs just fine. If I do zef install OpenSSL without a local copy, it fails with sk_num not being found, which is rather odd.

Could not confirm with a clean installation.

I think this problem should no longer happen. At least I was able to install OpenSSL on Debian 10 and Ubuntu 20.04.2 LTS (both coming with OpenSSL 1.1.1).

If I'm not mistaken, the following changes made things work:

• Add OpenSSL::Version #65
• the work from @ugexe for Installing fails on Debian Stable (buster) with "Cannot locate symbol 'sk_num' in native library 'libssl.so'" #82 (which removed stale precomp files)

Please note: The second change was only necessary if the libssl.so was not already present when attempting to install OpenSSL the first time.

However, I think (hope) that this issue could be closed now. It would be great if someone else double checks.
