I don't known for sure that this works but..; if DMD runs, I rather 
suspect that it's output will as well.

***I don't know of any damage this this could cause but I don't know 
that it is safe either.***

I mean, even if your processor is 64-bit, and you have a 32-bit OS 
installed, it'll work, since the 64-bit processor will just be running in 
32-bit mode.  But if you have a 64-bit OS, well, you can try.  I've never 
even *touched* 64-bit Linux so my utility comes to an end here.

DMD will generate 32-bit code
GDC has versions to generate 32-bit and 64-bit code

If you're going to use DMD, your OS needs to be able to run 32-bit code. 
If, like me, you run 64-bit ubuntu, you'll need a 32-bit chroot.

It doesn't require a chroot environment, just the appropriate 32 bit 
libraries, which essentially every distribution makes available.  I've run 
dmd on linux x86/64 with various linux distributions.  On fc6 I had to 
install two rpm's, compat-libstdc++-33 and glibc-devel.i386.  The box I 
was running fc6 on was an ec2 instance and the image it started with was a 
very very slim install (no compiler at all), so the latter is probably 
already installed on most boxes.  On debian I had to install libstdc++6, 
also often already installed.

The only thing you won't be able to do with dmd is create 64 bit 
applications.  As long as you're ok with creating 32 bit applications, 
you're fine.  MOST apps don't need the full 64 bit address space and the 
cost of the extra memory consumed by using pointers and longs that consume 
twice the memory.  Many can take advantage of the extra registers that 
become available to 64 bit apps.  So, it's all a balancing act.

Well, I've posted questions specifically about ubuntu 64 and got responses
back from them.  The only way that any of us (that participated in the
discussions) got it to work on ubuntu 64 was with a 32 bit chroot.  If you
can figure out the complete list of packages to makes dmd work under ubuntu
64, please tell me!  Ubuntu 64, by default, runs only 64-bit applications.

I don't use ubuntu, so I'm ill equipped to discuss what it takes to do 
anything there.
