Hi,

I’m trying to compile ruby 1.8.6 for native 64bit XP OS.  
I’m using MS Platform SDK for Windows Server 2003 R2 and building with  
64bit build environment.

Any one had tried this… the reason is we would like to run extension  
dlls in native 64bit. I appreciate if some one can reply with his  
thoughts or experience doing this.

I mainly have seen issues with :

- Running the configure bat file results an error that does not proceed  
to build the make file.  
C:\ruby-1.8.6original\ruby-1.8.6\win32\>nmake -alf “~tmp~.mak”  
NMAKE : fatal error U1077: ‘cl’ : return code ‘0x2’  
Stop.
- There are come assembly code in couple of files which can not be  
compiled in AMD64.
- There is also Context structure that is different than IX86

regards  
Wael

Is there any one who worked on building ruby for XP64 bit?

I don’t think it’s possible to build a 64 bit Ruby on Windows. See  
[http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/20176](http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/20176) and  
following.
