Error compiling ruby-2.5.1 '__rvm_make -j4'

[J-Krush]

Description

I am attempting to install ruby 2.5.1 via RVM. I am getting stuck in the compilation of this ruby.

Steps to reproduce

1. Installed RVM via the instructions here: https://rvm.io/rvm/install
2. rvm install 2.5.1

Alternatively I have:

• Installed latest xcode command-line-tools (manually as well)
• Tried rvm install 2.5.1 --with-openssl-dir=brew --prefix openssl``
• And a different way: RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix openssl) --disable-dtrace" rvm install "ruby-2.5.1"

Expected behavior

Clean install of ruby 2.5.1.

Actual behavior

• command
• make.log

The make.log file is far too long for a gist, so I created a snippet of what is actually displayed. It's essentially thousands of lines of this:

_Nullable /usr/local/include/stdlib.h:356:13: note: insert '_Nonnull' if the pointer should never be null extern char *suboptarg; /* getsubopt(3) external variable */ ^ _Nonnull

The error is with the stdlib, so I thought it would have something to do with xcode command-line-tools, but I installed those several times now.

Environment info

rvm info

Also, I'm new to Ruby and RVM, so let me know if I'm doing something dumb.
