I like to try out TLS 1.3. Unfortunately, as these things go, my Ubuntu 18.04 LTS comes only with the last OpenSSL version that doesn't support the new TLS version.

I'm a bit bamboozled on how to get Net::SSLeay working with my custom version.

I built the latest OpenSSL (1.1.1a) and installed it in my user home:

$ tar xvzf openssl-1.1.1a.tar.gz 
$ cd openssl-1.1.1a/
$ ./config --prefix=/home/cavac/bin/openssl
$ make -j24
$ make test
$ make install

[download]

So far, it all worked out nicely. But i can't get Net::SSLeay to build:

$ cpan

cpan shell -- CPAN exploration and modules installation (v2.20)
Enter 'h' for help.

cpan[1]> look Net::SSLeay                                             
+                                                                     
+                                                                     
+

Do i need to set some extra LD_LIBRARY_PATH or something? What about during runtime of my scripts, do i also need to set the environment variables or does Net::SSLeay remember?

I certainly want to make sure that only my local (self compiled) version of Perl uses this version of OpenSSL. I don't want to break other programs installed on the system.

perl -e 'use MIME::Base64; print decode_base64("4pmsIE5ldmVyIGdvbm5hIGdpdmUgeW91IHVwCiAgTmV2ZXIgZ29ubmEgbGV0IHlvdSBkb3duLi4uIOKZqwo=");'
