win32utils devel - Jun 2009 - building ruby 1.8.7 in windows 64-bit environment?

Hello,

I''m having difficulty in trying to figure out how to handle building 
ruby in a 64-bit Windows environment.

So far I have been able to build ruby in Windows using nmake on the 
command line. I have played with 1.8.7 and 1.9.1.

Version 1.9.1 seems to support building with a target platform of 64-bit 
Windows, however 1.8.7 does not. So, one possible solution for me is to 
use ruby 1.9.1. The problem is that I need to run rails and some other 
common gems, but these don''t seem to support 1.9.1 yet.

I need to compile in 64-bit mode because I am integrating this into a 
much larger software platform that is all built in 64-bit. There isn''t 
really a way to work around this.

Can anyone help with an idea of whether or not this is possible?

Or references to information I can find elsewhere?

One thread I was able to find on this mailing list was helpful, pointing 
to the fact that the 64-bit compiler doesn''t support __asm directives:

I haven''t been able to find much useful information on the web about 
this issue (maybe I''m not searching for the right things?), so any help
you might be able to provide would be extremely useful.

thanks so much,

Peter Pawlowski

1.8.x will not build on 64bits Windows, that was Ruby-core answer about it.

Only 1.9 is prepared to handled 64bits properly.

See above answer.

Well, that is not 100% true. Unless you need to load ruby as DLL from
a 64bits process, you''re not forced to have Ruby as 64bits, 32bits
process can run side-by-side thanks to SysWOW64.

Not possible for 1.8 line of code.

Search at ruby-core, this was raised a few months ago.

No, there isn''t much information, sorry.

Please review my statement before about 32bits running side-by-side
with 64bits. Unless you need to certificate 64bits installers (for
Windows Logo) or calling ruby as library form 64bits process, then you
don''t need 64bits Ruby.
