Bug #16905: Ruby required to build Ruby on Haiku?

• Status: Open
• Assignee: -
• Target version: -
• ruby -v: not yet built, last running version 2.7.0p0
• Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN

Building Ruby on Haiku results in the following error:

executable host ruby is required. use --with-baseruby option.

Build environment:

~> uname -a
Haiku shredder 1 hrev54197 May 14 2020 06:44:52 x86_64 x86_64 Haiku

Current recipe and patch set:

make distclean doesn't solved the problem.

This could perhaps be a bug. I think you can normally build "miniruby"
if a base ruby is not available on the computer system, and then the
compilation step uses that miniruby for the compilation part. At the
least this is how I understood it to work.

Hopefully someone from the core team can have a look - would be great
if ruby could work on HaikuOS out of the box.

Forgot to mention i maintain the ruby port since some years, so i am definitely sure the earlier versions never had problem like this.

2.7.0p0 is the current running version on Haiku. I will look deeper into it later to find the culprit.

According to the log,

executable host ruby is required. use --with-baseruby option.
uncommon.mk:866: recipe for target 'parse.c' failed

parse.y file has been modified, or its timestamp changed at least.

I didn't edited that file and haven't changed the timestamp, so while your idea makes sense, i don't trust this error message at all, as this is from make, not from flex/bison, so it is way too generic error to be able to tell whats going on here. Let's see what is in the debug output...
