Subject: Thread library issue with 64-bit Ruby on OS X

Hi all,

OS X 10.4.9
Dual Xeon, dual core (Mac tower)

I built 1.8.6-p36 using gcc -m64 -Wall. It seemed to go fine, until the 
very end when it gave me this warning:

ld64 warning: in /usr/lib/libobjc.dylib, missing required architecture 
x86_64 in file

I ignored it, installed anyway, and most things seem to work. One thing 
that failed (which I noticed as a result of the post-install from 
rubygems) was that it won't load the thread library:

LoadError: Failed to load 
/opt/test/lib/ruby/site_ruby/1.8/i686-darwin8.9.1/thread.bundle
         from 
/opt/test/lib/ruby/site_ruby/1.8/i686-darwin8.9.1/thread.bundle
         from /opt/test/lib/ruby/site_ruby/1.8/thread.rb:5
         from (irb):1:in `require'
         from (irb):1

So, I went to the ext/thread source directory and rebuilt. This was the 
result:

gcc -Wall -m64 -I. -I/opt/test/lib/ruby/1.8/i686-darwin8.9.1 
-I/opt/test/lib/ruby/1.8/i686-darwin8.9.1 -I. -DUSE_MEM_POOLS 
-fno-common -g -O2 -pipe -fno-common  -c thread.c
thread.c: In function 'wait_condvar':
thread.c:676: warning: passing argument 1 of 'rb_ensure' from 
incompatible pointer type
cc -dynamic -bundle -undefined suppress -flat_namespace -o thread.bundle 
thread.o -L"." -L"/opt/test/lib" -L.     -ldl -lobjc

So, outside the warning, it built successfully. I installed it again 
(and removed the old one to be sure), but I still get the same error 
when I try to load it.

Any ideas?

Thanks,

Dan
