Hey Alex -

Check out the binary-builder repo on GitHub [1]. In particular, the Ruby
blueprint [2].

The binary builder is used by our CI pipeline [3] to produce the binaries
bundled in the buildpacks. The README [4] includes instructions on how to
run binary-builder locally, and the CI repository includes a script [5] for
building binaries via a script.

Best,

Matt

I was able to solve the problem with ruby by adding --enable-load-relative
to ./configure command.

Still it would be useful to know how do you build binaries for buildpacks.

Thank you,
Alex L.

Hello, everyone.

I try to create custom ruby-buildpack to support Power8. This means I need
to rebuild ruby binaries. I’ve wrote some scripts that build necessary
binaries and upload them to S3 [1]. Here is a script that build ruby [2].
Still after I tried to run an app I’ve got this error [3], that said “`require':
cannot load such file -- rubygems.rb (LoadError)”. I think that potential
problem could be in the way I build ruby binary.

Could you please tell what do you use to build binaries for buildpacks?
