.rbenv/plugins/ruby-build/bin/ruby-build: line 1176: patch: command not found

[palladius]

Steps to reproduce the behavior

• install rbenv from GIT on your Synology
• install ruby-build on synology
• install a rubie

Expected vs. actual behavior

I'm sure this is not this maintainer fault, but would love to find a pointer to how to install PATCH on my system or maybe make it work without patch.

Hi, thank you for reporting and sorry for the trouble. The command patch is usually part of “standard” GNU utilities on Linux machines and we did not expect that it would be missing on a machine that has the rest of the tooling to compile programs.

I'm not familiar with how Synology DSM packages additional software for downloading on your machine, but you could check their documentation and see if there is an optional package that you can additionally install that provides the patch util.

[hsbt]

Synology may used debian fork distribution. You can install patch with apt install patch.

First thanks for the answer - I was NOT expecting that ruby-build works on synology but I wanted to leave a trace for people to find their way here with solutions.

My synology has no apt, neither ipkg and has discontinued ruby (sigh!) so i guess I'll renounce to ruby on that machine.

[hsbt]

OpenSSL-1.1.1r and 1.1.1s are already released.

https://www.openssl.org/news/openssl-1.1.1-notes.html

I'll check them for removing our local patch.

[mislav]

@hsbt Since our openssl patch only affects building openssl-1.1.1q, I'd vote for keeping it in code for a while still.

This is to keep compatibility with custom build formula that still have install_package "openssl-1.1.1q" in them.

[mislav]

Update: since https://github.com/rbenv/ruby-build/pull/2088, none of our built-in Ruby definitions link to openssl-1.1.1q, therefore the installation process is no longer dependent on patch being present on the system.

[palladius]

Wow. This is amazing @mislav !
