Build 32 bit version of ruby 1.92 on snow leopard

Ruby

Hello,

Anybody can help me , I have googled and spend the last two night
searching forum for the magic terminal sentence that will build a 32 bit
version of Ruby 1.92 on Snow Leopard.

I need it because “Bowline” ( an application that build stand alone
executable from ruby/Javascript/CSS)
only work with Ruby 1.9 32 bit.

Can someone help

Thanks

The magic incantation you need is something like

ARCHFLAGS="-arch i386"

It’s not quite that simple, but I don’t remember what exactly I had to
do to make it work. Google should be able to tell you how to apply it to
the compile now that you know what command you want.

You can test the result to see if it built it the way you wanted or not
by finding one of the binary files that comes from the compile, and
using the ‘file’ command:

$ file /usr/bin/ruby
ruby: Mach-O universal binary with 2 architectures
ruby (for architecture ppc7400): Mach-O executable ppc
ruby (for architecture i386): Mach-O executable i386

My current version of ruby (version 1.8.7) has both a 32-bit PowerPC and
. . . huh? Where’s my 64-bit version??

$whereis ruby
/usr/bin/ruby

$file /system/library/frameworks/ruby.framework/ruby
/system/library/frameworks/ruby.framework/ruby: Mach-O universal
binary with 3 architectures
/system/library/frameworks/ruby.framework/ruby (for architecture
x86_64): Mach-O 64-bit dynamically linked shared library x86_64
/system/library/frameworks/ruby.framework/ruby (for architecture
i386): Mach-O dynamically linked shared library i386
/system/library/frameworks/ruby.framework/ruby (for architecture
ppc7400): Mach-O dynamically linked shared library ppc

Well, that’s not good. The version of Ruby that came with SnowLeopard
has THREE architectures in it: PowerPC, 32-bit Intel, and 64-bit Intel.
Now, how the heck did a two-architecture version get in my /usr/bin
folder? Well, anyway, hopefully that’ll help you compile a 32-bit
version of 1.9.2
