Linker error cross compiling for raspberry pi

[Jackson Slater]

I am using ubuntu, trying to cross compile a d application for 
Raspberry pi.

I installed the "gdc-8-arm-linux-gnueabihf" package, but now when 
I try to compile, I get a linker error:

trying to cross-compile this:
---
import std.stdio;

void main()
{
   writeln("Hello, Pi!");
}
---

But when I compile (using the command `arm-linux-gnueabihf-gdc-8 
main.d`) I get this error:

---

Can anyone help me fix this?
Thanks
