I'm posting here because I don't know if this also occurs with DMD. I'm using GDC 0.17 on Mac OS X 10.4.

Take these two modules:

//////////////////////////////////////
module uno;

private import std.boxer;

version(err)
        private import dos;
else
        Box foo()
        {
                return box(0);
        }

void main()
{
        auto i = unbox!(int)(foo());
}
//////////////////////////////////////
module dos;
private import std.boxer;

Box foo()
{
        return box(0);
}
//////////////////////////////////////

If I just compile uno.d, it works. But if I do:

$ gdmd uno.d dos.d -version=err

I get:

/usr/bin/ld: Undefined symbols:
__D3std5boxer24__T16unboxCastIntegerTiZ16unboxCastIntegerFS3std5boxer3BoxZi
collect2: ld returned 1 exit status

I also have problems trying to use MinTL wtih std.boxer.Box.

dmd uno.d dos.d -version=err

FYI, I tried this on Windows (DMD 0.145), and I got a different compile error:

dos.obj(dos)
Error 42: Symbol Undefined _assert_3std5boxer

So it seems the problem is with GDC. That error is fixed with the "Burton fix"  ;)

extern (C) void assert_3std5boxer () {}

Thanks for trying that.

As promised, here's the minimal test case:

module test;

import std.boxer;
import mintl.all;

void main()
{
        Stack!(Box) stack;
}

In my case, compiling with:

gdmd test.d -I../.. libmintl.a

I get:

__Class_5mintl3seq33__T11SeqDelegateTS3std5boxer3BoxZ11SeqDelegate
__Class_5mintl3seq43__T19SeqWithKeysDelegateTiTS3std5boxer3BoxZ19SeqWithKeysDelegate

__init_24TypeInfo_S3std5boxer3Box
collect2: ld returned 1 exit status

I had to update MinTL to get it to compile.
