 I've tried all sorts of stuff and looked all over, but I'm completely at a 
 loss. How do I link in a static lib on the command line?


And I don't mean "with C" or anything like that, just ordinary D.


 type main.d


module main;
import theLib;
void main()
{
    foo();
}


 type theLib.d


module foo;
import std.stdio;
void foo()
{
    writeln("In foo");
}


 dmd theLib.d -lib



 dmd main.d -LtheLib.lib

main.obj(main)

main.obj(main)
 Error 42: Symbol Undefined _D3foo3fooFZv
--- errorlevel 2

Same results for "-LtheLib".
I saw something about "-L-ltheLibNameHere" somewhere, but "-L-ltheLib.lib" 
gets me:

And with "-L-ltheLib" the message just says "LTHELIB" instead of 
"LTHELIB.LIB"

Don't you just include it as one of the arguments, like all of the .d files? I 
don't know. I haven't had a need to link in static libs before, and I usually
do 
the linking step myself with gcc so that I can get a static binary (since -L-
static doesn't currently work with dmd).

theLib.lib

 main


In foo
------------------------

Ok, so that works, but with a linker warning. However, that can't be used 
with rdmd, becuase rdmd will interpret "theLib.lib" as the name of the 
program to be run.

dmd just does a pass through:

-L<arg-to-pass-to-linker>

I have no clue what optlink's cryptic syntax is, but on Linux, it would be  
something along the lines of:

-L-Llibdir -L-lmylib

To give you an idea.  Now go find the command line syntax for optlink :)   
Also, you can try dmd -v to see what link line it calls normally, I'm sure  
it has some of those options in there.
