Giving multiple optflags raises unrecognized option error.

[k0i]

Steps to reproduce the behavior

It can be reproduced by executing the following command:

RUBY_CONFIGURE_OPTS='optflags="-O0 -fno-omit-frame-pointer"' ruby-build 3.3.0 ./

Expected vs. actual behavior

Expected

Although I found the same issue in the past, the problem was regarded as fixed then.
So, this command should also be successful.
(If ruby-build doesn't support taking optflags as its argument, please kindly close this issue.)

Actual

It raises the following error:

-> ./configure "--prefix=$HOME/.rbenv/versions/3.3.0" --enable-shared --with-ext=openssl,psych,+ optflags="-O0 -fno-omit-frame-pointer"
configure: error: unrecognized option: `-fno-omit-frame-pointer"'

It succeeds if I attempt to configure manually in the ruby repository.
(I attached the truncated manual build result in this section just in case 🙇 )

I will close this issue as I can solve this is not a bug.
Sorry for disturbing you.

RUBY_CONFIGURE_OPTS is not able to pass configure values that have spaces, even if those values are quoted like in your example.

However, you may pass those values as arguments to ruby-build after a -- argument separator:

ruby-build 3.3.0 ./ -- optflags="-O0 -fno-omit-frame-pointer"

Thank you for your kind explanation! 🙇 🙇
