------------------------------------------------------------------
Certainly, I should have done that when creating the issue - sorry.
I attached all the files I used when verifying the bug, but here are the
highlights:
The Java interface C is defined as:
{code}
public interface C extends B, A {
void c();
}
{code}
The generated header file for it, C.h, contains (copying only the relevant
lines):
{code}
#include "testjcc/B.h"
namespace testjcc {
class A;
}
namespace testjcc {
class C : public ::testjcc::B {
{code}
As you can see, A has a forward declaration, but is not included or inherited.
Changing the order of the interfaces in the Java file changes the generated
file so that A is included and inherited instead.
I'd expect both A.h & B.h to be included, and the first line of the class to be:
{code}
class C : public ::testjcc::B, public ::testjcc::A {
{code}

>
> When generating wrapper for a Java interface that extends more than one other
> interface, then only the first extended interface is used when generating the
> C++ class.
> In cpp.header(), the code snippets:
> {code}
> if cls.isInterface():
> if interfaces:
> superCls = interfaces.pop(0)
> {code}
> and:
> {code}
> line(out, indent, 'class %s%s : public %s {',
> _dll_export, cppname(names[-1]), absname(cppnames(superNames)))
> {code}
> are likely responsible.
