I've discovered that the ubuntu linux distribution refuses to run 32 bit applications out of the box.  Are there plans for releasing a 64 bit version of dmd?  Is there anyone more experienced than me that has created a .deb (debian package) file that I can use?

jhouse@server:~/dmd/bin$ ls -al dmd
-rwxr-xr-x 1 jhouse jhouse 1009284 2007-03-26 00:45 dmd

jhouse@server:~/dmd/bin$ ./dmd
-bash: ./dmd: No such file or directory

jhouse@server:~/dmd/bin$ ldd dmd
        not a dynamic executable

jhouse@server:~/dmd/bin$ file dmd
dmd: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared libs), stripped

Try installing the "ia32-libs" package.

Works just fine for me:

Worked like a charm!  I'm surprised that wasn't on the ubuntu x86 64-bit forum.  Time to go make another post...

Any further tips on getting rebuild/dsss to work?  I'm getting linker errors.  I'm assuming dmd is generating a 32 bit executable and failing to link with 64 bit libraries.  Can dmd generate a 64 bit executable? I'm not sure how to configure it to do so.  I did try hacking at the rebuild config files to see if I could get it to work (resulting file below).

Can gdc do better?

gdc has an amd 64 binary release that works great.  No rebuild config changes required (besides telling /etc/rebuild/default to use gdc-posix).  There's a related thread from earlier this month that says dmd does not support 64 bit yet.

This has nothing to do with rebuild/dsss. I had the same problem with "pure" dmd. (Sorry for forgetting to mention that in my previous post)

> I'm assuming dmd is generating a 32 bit executable and failing to link with 64 bit libraries. 

Yes, that's exactly what's happening AFAIK

I got it to work was by running dmd in a 32-bit chroot. See http://ubuntuforums.org/showthread.php?t=24575 for step-by-step instructions.
You'll want to install DMD and gcc+binutils into the chroot, and create a symlink named "dmd" (outside the chroot) to the do_chroot script they provide.

> Can dmd generate a 64 bit executable? 

No, DMD can only generate 32-bit executables.

> Can gdc do better?

Although I haven't been able to compile it myself on amd64, the binary distribution[1] worked straight out of the box IIRC. It's a native 64-bit executable and produces 64-bit code. (It's supposed to also be able to generate 32-bit code, but I haven't tried that)

Note that there is at least one issue with it, but considering this is the first release to support 64-bit it works pretty well. Unfortunately, that issue means that Tango's formatted output functions don't compile and (G)Phobos' formatted output doesn't support structs...
Other than that I haven't had any problems with it, as far as I can remember.

Now that I've gotten gdc to work on ubuntu with AMD64, I've started experimenting with the coverage analysis.  gdc -cov will build object files, but doesn't link.  Any tips?
