Hello,

dmd now exports all values successfully. But when I try to export a class, I get the following errors:

"Error 42: Symbol Undefined _D5mydll1t7__ClassZ
Error 42: Symbol Undefined _D5mydll1t5_ctorMFZC11mydll1t"

Source of mydll.d is:

export class t {

	export this();

}

Source of mydll2.d is:

import std.stdio: writefln;

export class t {

	export this() {
		writefln("hello world!");
	}
}

Source of test.d:

pragma(lib, "mydll.lib");
import mydll;

void main() {

	t myTest = new t();

}

When I export D5mydll1t7__ClassZ in my def-File, I can compile it but when I try to create a new instance of t, I get an access violation :(.

Never tried exporting a class, but there's some info on this page:
