I installed rbenv and tried to install ruby 1.9.3 on Debian 9 as instructed here https://github.com/rbenv/ruby-build/wiki
OpenSSL bindings on Debian
Because of OpenSSL incompatibility in Debian (7.5 and above), Ruby might fail to compile without patching it first:curl -fsSL https://github.com/ruby/ruby/commit/1e7a929c1d44d7a368fbe379211183ac6c972920.patch | \ rbenv install --patch 1.9.3-p484
and the response I got was
Installing ruby-1.9.3-p484...
patching file ChangeLog
Hunk #1 FAILED at 1.
1 out of 1 hunk FAILED -- saving rejects to file ChangeLog.rej
patching file ext/openssl/ossl_ssl.c
Hunk #1 succeeded at 1985 (offset -244 lines).
BUILD FAILED (Debian 9.4 using ruby-build 20160913)
Well, the changes in ChangeLog are not needed for ruby to work, or course. Then I found this https://github.com/mathbruyen/computers/blob/master/computers/AspireOne.md
curl -fsSL https://github.com/ruby/ruby/commit/1e7a929c1d44d7a368fbe379211183ac6c972920.patch | filterdiff --strip=1 -i a/ext/openssl/ossl_ssl.c | rbenv install -p 1.9.3-p484
from which I was able to find a way to apply only the hunk for OpenSSL related file. Filterdiff can be installed on Debian: apt install patchutils .
Result of installing Ruby 1.9.3-p484

Now I noticed there still is a an openssl related error. So I tried another libssl-dev-package:
sudo apt install libssl-dev
Now installing ruby 1.9.3-p484 was without errors, great!! But even though the installation was now without errors, openssl is still not available in ruby.

EDIT: For ruby 1.9.3-p484 it says in the log:
Failed to configure openssl. It will not be installed.
That's why installation was successful, but openssl was not working. Looking for the word 'error' in the logs I also found " error: ‘SSLv3_method’ undeclared", which was fixed in a separate patch.
The Wiki additionally says all the following:
The openssl extension of Ruby version before 2.4 is not compatible with OpenSSL 1.1.x. At the moment, most Linux distributions that come with OpenSSL 1.1.0 have a separate package for OpenSSL 1.0.x.
On Debian 9 (stretch), it is libssl1.0-dev (note installing this would remove libssl-dev).
and
OpenSSL “SSLv3_method undeclared” error
For older Ruby versions like 1.9.3 the above patch will not work, use this instead:curl -fsSL https://gist.github.com/FiveYellowMice/c50490693d47577cfe7e6ac9fc3bf6cf.txt | \ rbenv install --patch 1.9.3-p551
So, in my setup the valid steps are:
1. sudo apt install libssl1.0-dev
2. curl -fsSL https://gist.github.com/FiveYellowMice/c50490693d47577cfe7e6ac9fc3bf6cf.txt | rbenv install --patch 1.9.3-p551
Now it works fine:
user@debian:~$ rbenv rehash
user@debian:~$ rbenv versions
system
* 1.9.3-p484 (set by /home/user/.ruby-version)
1.9.3-p551
user@debian:~$ rbenv local 1.9.3-p551
user@debian:~$ irb
irb(main):001:0> require 'openssl'
=> true
irb(main):002:0>
Hopefully this would help someone!
