Gem configuration options

Ruby
1

How do you pass configuration options to extconf.rb when installing a
gem?
Specifically I’d like to configure ruby-gd.

$ gem install ruby-gd
??something?? --with-freetype --with-ttf --with-jpeg --enable-gd2_0

Thanks.

gem install ruby-gd – --configure-options

Is that a new option? I thought it was --build-flags.

~$ gem --version
1.0.1
~$ gem help install
Usage: gem install GEMNAME [GEMNAME …] [options] – --build-flags
[options]

– tells RubyGems to stop processing options. --configure-options or
–build-flags are just dummy names for whatever it is you actually
want to specify.

That makes sense. Thanks.
