Consider the following two modules:
1. test.d:
module test;
import lib.a;
void main() {
foo();
}
2. lib/a.d:
module lib.a;
extern(C) void foo() {}
When compiled separately (dmd -c lib/a.d; dmd test.d a.o), the
function in 'a.o' is mangled as 'foo', but the reference in
'test.o' is mangled as '_D3lib1a3fooFZv', which leads to a
link error. I would expect both of them to be either plain C
mangling, or fully qualified D (better). What is the reason
for current behavior?
If that is happening you hit a bug.
It seems unlikely though.
Could you elaborate a bit? How should extern(C/C++) definitions
be mangled - fully qualified or not, and why is the reference to
extern(C/C++) D-mangled? The spec seems to say nothing about it.
