Subject: Re: 64-bit Ruby for OS X ?

I personally won't use anything that isn't under x64.  No offense to people
who are scared about memory usage but I prefer to be able to address my
12GB+ of Ram on each of my servers without needing to hack my Kernel for
anything more than security, and speed.  I've had no problems with the
memory the gentleman reported with memory consumption crawling on OSX, BSD
or Debian so perhaps it's just a bad compile in his behalf? Our Daemons that
monitor our main server would have caught a memory leak if it was happening
but they haven't yet and even on a check with the amount of hits we get, our
total memory usage for Ruby is only 1.5GB total for all 15 Processes that
run Ruby.

Read:

http://developer.apple.com/documentation/Darwin/Conceptual/64bitPorting/buil
ding/building.html#/ 
/apple_ref/doc/uid/TP40001064-CH208-BHCHDAFB

For 1.9 I configured:

$ LDFLAGS="-arch x86_64" CFLAGS="-arch x86_64 -mmacosx-version- 
min=10.5 -D_FILE_OFFSET_BITS=64" ./configure

(ignore the error from fuse, it seems configure doesn't use CFLAGS  
there)

`make test` finishes most tests, `make test-all` fails with a missing  
encoding (maybe iconv isn't compiled 64-bit?)

The built ruby is 64-bit though:

$ ./ruby -ve 'p 1.size'
ruby 1.9.1p129 (2009-05-12 revision 23412) [i386-darwin9.7.0]
8

Compared to Apple ruby:

$ ruby -ve 'p 1.size'
ruby 1.8.6 (2008-08-11 patchlevel 287) [universal-darwin9.0]
4

I imagine the same configure flags would work for 1.8.
