Sounds cool, but dvm-0.2.0-linux-32 is just giving me "Illegal

Ok, strange. I built the tool on Ubuntu 11.04, maybe it's too new. How can
I build it to work on as many platforms as possible? The runtime
dependencies are just the same as a regular C application and zlib.
You know, I'm far from a Linux expert, but making compatible linux binaries
seems to be quite a nightmare. In fact, I just recently went through hell
myself trying to figure out how to compile a Hello World CGI app on my linux
system and have it actually work on another linux system.
You can follow my fun-filled adventures through it with these discussions:
Yeah, I read parts of those threads.

But the bottom line seems to be: Linux is in a bigger DLL hell than windows
has ever been, and I don't think *anyone* actually knows how to do it.
In my case, I ended up just installing an older version of linux in a VM and
compiling inside that (CentOS 4, largely because I needed to be able to run
on a CentOS server that wasn't happy with my Kubuntu 10.04 executables). The
resulting binaries did work on my Kubuntu 10.04 machine, too, so I guess the
trick is to just compile on the oldest machine you can. Go figure: All the
focus everyone puts on updating to newer versions, and it ends up best to
stick with the older versions - not because the older ones were better, but
just *because* they're older. Meh. Anyway, pardon the rant :/
Hehe.
You'd think there'd be a way to compile in a backwards-compatible way on
linux, but I'm getting the impression that if it's possible, no one actually
knows how.
Wouldn't it just be possible to use an older version of GCC?

Thanks :) I think I'm almost there. I've been using D2/Phobos/RDMD for the
past year or so (plus my usual machine is a windows box), so I had a lot of
setting up to do, but I think I've almost got it now. When I do, I'll post
the final binary in case it helps anyone else (I can only make a 32-bit
binary though).
