2.7.2 build fails on MacOS 10.15.7 with homebrew, unsupported option '--with-readline-dir

[jrochkind]

Trying to run:

ruby-build 2.7.2 ~/.rubies/ruby-2.7.2

I think it's actually failing trying to build the openssl dependency, Installing openssl-1.1.1i....

Last lines of log file:

make: *** [all] Error 2

It's trying to use a --with-readline-dir option that the clang it's trying to invoke does not recognize, I guess?

I have installed rubies before on this machine that I think now are failing -- maybe it now tries to build against openssl 1.1.1i when before it used previous openssl versions, and that's what's somehow failing? Not really sure.

Try brew install [email protected] and then building all Ruby versions by setting

RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix [email protected])" ruby-build 2.7.2 ...

That will avoid rebuilding openssl in favor of Homebrew's openssl.
