rbenv install 2.3.8 fails on Ubuntu 20

[ikudosi]

Hi everyone! Hopefully someone can help me with this problem I've been trying to solve all day.

I'm new to ruby trying to build version 2.3.8 so I can work on a legacy app... and after scouring the web and realized it may be due to my Openssl version (currently set at 3). I came across a tutorial to download / extract Openssl 1.0... which I did to a /old-openssl-version-1.0.2 directory:

I then ran export RUBY_CONFIGURE_OPTS="--with-openssl-dir=/old-openssl-version-1.0.2 --with-readline-dir=/usr/include/readline" followed by rbenv install 2.3.8 but still doesn't seem to build.

Log output:

Hi, I'm looking at this error:

configuring openssl
Ignore OpenSSL broken by Apple.
Please use another openssl. (e.g. using `configure --with-openssl-dir=/path/to/openssl')
Failed to configure openssl. It will not be installed.

I don't know why this happens, since you've provided --with-openssl-dir yourself, and the version you've installed probably isn't related to Apple's versions of OpenSSL that ships on Mac machines.

This is also weird:

./tool/runruby.rb:72: warning: Insecure world writable dir /mnt/c in PATH, mode 040777

This leads me to believe that you are under WSL, which should not be a problem, but it's possible that it affects things slightly.

I have no answers, sorry; just these observations. Note that installing old Ruby versions might be more trouble than it's worth, and that updating the Ruby version of your app might be a more fruitful endeavor.
