Hi,
   I need to compile a D program in FreeBSD. I've followed the FreeBSD instructions. So far, dmd is creating the obj file, but there appears to be a problem with the linker. The error messages are very cryptic. I was hoping someone might have an idea what they mean and what I'm doing wrong here.

<CODE>
$ more hello.d
import std.stdio;

int main(string[] args)
{
    writefln("Hello World\n");
        return 0;
}
$ uname -a

$
$
$ dmd hello.d

Can you check, whether dmd is explicitly linking with -pthread?
It might an issue of libkse vs. libthr?
https://github.com/freebsd/freebsd/blob/0680c1f5fe159bba69a242568af0db7d7dc15a79/lib/libthr/thread/thr_clean.c#L49
We're building the binary releases on FreeBSD 8.4, so upgrading might help too.

That is a very old FreeBSD release.  dmd from ports doesn't even compile for anything less than FreeBSD 8.  I suggest you at least upgrade to 7-stable, better another release branch completely.

Thanks for the info. The issue is a FreeBSD 6.2 system that unfortunately can't be upgraded. Do you think it will run if it's compiled on an x86 FreeBSD 8.4 system and moved to the 6.2 system?

No idea, all I know is that dmd in ports was disabled on FreeBSD/7 years ago:

http://svnweb.freebsd.org/ports?view=revision&revision=267685

Maybe you can patch dmd or whatever else is necessary to get it working on older FreeBSD versions.
