Ability to Pass Flags to Ruby Build (Jemalloc Support)

[Ashwin Vaswani]

Hello!

I was wondering if there were any way to pass RUBY_CONFIGURE_OPTS similar to how ruby-build works:

RUBY_CONFIGURE_OPTS="--with-jemalloc=$(brew --prefix jemalloc)" asdf install ruby 3.2.2. From what I understand, this might be a limitation due to what release types are available in the ruby-builder repo?

Could we consider adding the ability to publish builds for Ubuntu with jemalloc?

Thank you!

Seeing #505 (comment) this is probably unlikely

I think it is possible to workaround with LD_PRELOAD, see docker-library/ruby#182 for lots of comments on that and it looks like this Heroku buildpack also uses that technique.

Thanks for the context and for linking me to the other thread! Will try out the LD_PRELOAD workaround and report back 👍🏾
