Cannot do a universal build of Ruby 1.9.2 on MAC OS X 10.6

Ruby

Hello,
I have downloaded ruby-1.9.2-rc1.tar.gz from here:
ftp://ftp.ruby-lang.org/pub/ruby/

I am trying to build it on 64bit mac osx, 10.6 in 32 bit kernel mode.
(uname -m gives i386)

I do the following:

  1. ./configure --with-arch=x86_64,i386 —> a universal build
  2. Make —> gives error

…
ld: warning: in utf_8.o, file was built for i386 which is not the
architecture being linked (x86_64)
ld: warning: in newline.o, file was built for i386 which is not the
architecture being linked (x86_64)
Undefined symbols:
“_main”, referenced from:
start in crt1.10.6.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
make: *** [miniruby] Error 1

Any idea why?

Thanks

It’s because the step that builds libruby.dylib doesn’t care about your
-arch flag settings. I use this patch:

http://github.com/jameskilton/rvm/blob/7753bcc7c3b6da8d61900efb41f538824b0dc3c0/patches/ruby/1.8.7/osx-arch-fix.patch

to allow me to specify what architecture to built. If this works for a
universal binary I’d love to know, but last I checked I could still only
build for a single arch.
