It seems that the stuff that DMD outputs to GCC on Linux is misconfigured for static linking.  I've observed this on several machines with various Linux distros, all of which can statically link a C hello world program successfully with the machine's GCC install.

hello.d:

import std.stdio;

void main() {
    write("Hello, world\n");
}

$ dmd -L-static hello.d
/usr/bin/ld: cannot find -lgcc_s
collect2: ld returned 1 exit status
--- errorlevel 1

Yet somehow when I compile/link a C hello world on the same machine it Just Works:

hello.c:

#include <stdio.h>

int main() {
    printf("Hello, world.\n");
    return 0;
}

$ gcc -o hello -static hello.c
$ ./hello
Hello, world.
$ file hello
hello: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), statically
linked, for GNU/Linux 2.6.15, not stripped

The issue is that -Lxxx passes the parameter like this:

-Xlinker xxx

Which means to gcc "pass this argument to the linker"

Whereas your gcc compile line is passing -static to the compiler.

doing this:

gcc -Xlinker -static -o hello hello.c

should result in the same failure (not tested).

It's not that dmd outputs misconfigured code, it's just that the link line is not geared towards static linking.  I'm not sure you want to do static linking anyways.  It's not supported by GCC IIRC.

You can fix this by doing dmd -v, then running the link line, removing the -Xlinker arg in front of -static.
