Bug #7819: configure script doesn't recognize valid options

• Status: Closed
• Assignee: -
• Target version: 1.9.3
• ruby -v: ruby 1.9.3p385 (2013-02-06 revision 39114) [x86_64-darwin12.2.0]

When configuring the latest version of Ruby, the configure script issues warnings about "unrecognized" but valid (?) build options.

To reproduce:

1. Untar the 1.9.3-p385.tar.gz

2. Give the following options to the configure script:

   ./configure --prefix=/usr/local/ruby-1.9.3-p385
   --with-openssl-dir=/usr/local
   --with-readline-dir=/usr/local
   --with-yaml-dir=/usr/local
   --with-gdbm-dir=/usr/local
   --with-libffi-dir=/usr/local

The result is this warning, both at the top and the bottom of the configuration output:

configure: WARNING: unrecognized options: --with-openssl-dir, --with-readline-dir, --with-yaml-dir, --with-gdbm-dir, --with-libffi-dir

Based on discussion in irc and the results of the build, I think that the warnings are bogus. That is, those options are recognized and used in the build.

You're right, it's just a warning.
Or, just use only --with-opt-dir=/usr/local instead.

So the --with options are correct to use? Even with Ruby-2.0.0-p0?

Yes, it is correct.
Why it shows such warnings is configure itself actually ignores them, but later build process use them.
