Building Ruby extensions on OS X Tiger

[Richard Kilmer]

Tony Arnold posted this on the Rails wiki:
_____

Mac OS X Tiger ships with Ruby 1.8.2 pre-installed. However,
rbconfig.rb needs to be edited if you want to build any gems. (from
Rich...not gems, native extensions)

Edit rbconfig.rb

sudo pico -w /usr/lib/ruby/1.8/powerpc-darwin8.0/rbconfig.rb
Now remove -arch i386 from the CFLAGS and LDFLAGS variables.

You will also need to change:
CONFIG["LIBRUBYARG_STATIC"] = "-l$(RUBY_SO_NAME)-static"
to:
CONFIG["LIBRUBYARG_STATIC"] = ""
_____


NOTE: This is only important if you are building native extensions
(not pure ruby ones)...but it does suck when you run into it...so its
worth fixing.

Chad is working on a gem that you can install which fixes this too.

You are indeed on the cutting edge ;-)

You know, it's this kind of tenderfoot gem file that takes
the machismo out of hacking a few core ruby files.

ARCH_FLAG should be "-arch ppc" on darwin. As what is it
defined, and RUBY_SO_NAME?

Should we update the rbconfig.rb again? KirinDave on irc also found
another problem with the RC_CFLAGS environment variable causing
problems with, for example, RubyInline.

I thought I might release another version of my fixer upper gem.

From where has the flag come?

CONFIG["RUBY_SO_NAME"] = "$(RUBY_INSTALL_NAME)"

Do you have a problem at linking with the static library?

For what is RC_CFLAGS used, and where is it set? I think ruby
never use it.

Haven't tried it.

never use it.

$ grep RC_CFLAG /usr/lib/ruby/1.8/powerpc-darwin8.0/rbconfig.rb

CONFIG["LDSHARED"] = "cc $(RC_CFLAGS) -dynamic -bundle -undefined
suppress -flat_namespace"
CONFIG["LIBRUBY_LDSHARED"] = "cc $(RC_CFLAGS) -dynamic -bundle
-undefined suppress -flat_namespace"

This is looking like a plain error. Maybe a typo? RC_CFLAGS appears
to be used in darwin to allow for customized CFLAG settings. Does
this make sense to anyone? Seems like it should be changed.

Do you mean they are misconfiguration by Apple, but not a bug
of configure.in? Sorry for noise.

Sorry for the VERY delayed response. It is a misconfiguration by Apple.
