‘arg0’ was not declared in this scope

[ReneHollander]

The generated C++ code sometimes wants to use an argument arg0 that is not declared in the function protoype. I assume that the issue is on my end, because it worked before. I didn't work on the project for a few months and I can't recall if it actually worked or how to fix it. The provided code is only from one of the methods that wants the arg0 argument. There are many more that aren't declared correctly.
But I am also getting the following warnings from the Generator:

Warning: First parameter of caller method call() or apply() for member function pointer org.duktape.duktapejava.Duktape.Function is not a Pointer. Compilation will most likely fail.
Warning: First parameter of caller method call() or apply() for member function pointer org.duktape.duktapejava.Duktape.FatalHandler is not a Pointer. Compilation will most likely fail.
Warning: First parameter of caller method call() or apply() for member function pointer org.duktape.duktapejava.Duktape.Function is not a Pointer. Compilation will most likely fail.
Warning: First parameter of caller method call() or apply() for member function pointer org.duktape.duktapejava.Duktape.FatalHandler is not a Pointer. Compilation will most likely fail.

I debugged the Generator a little, and all the warnings are caused by the allocate function not having an argument that is a Pointer.

GCC output:

/home/rene/Dropbox/Code/duktape-java/build/tmp/native/duktape-java-linux-x86_64.cpp: In function ‘int JavaCPP_org_duktape_duktapejava_Duktape_00024Function_allocate_callback()’:

Snipped from the generated C++ code:

JNIEXPORT int JavaCPP_org_duktape_duktapejava_Duktape_00024Function_allocate_callback() {
    return JavaCPP_org_duktape_duktapejava_Duktape_00024Function_allocate_callback_instance(arg0);
}

The used Java definition:

@org.bytedeco.javacpp.annotation.Namespace("")
public static abstract class Function extends org.bytedeco.javacpp.FunctionPointer {

    static {
        LibraryLoader.load();
    }

    public Function() {
        allocate();
    }

    private native void allocate();

    public abstract int call(duk_context ctx);

}

@Namespace("")
@Name("duk_context")
public class duk_context
    extends Pointer
{

    static { org.duktape.duktapejava.LibraryLoader.load(); }
}

Fixed in the latest commit above. Thanks for reporting!

Are you planning to release a patch? Setting the Namespace to "" is mandatory if someone wants to generate bindings for C code.

Fix included in version 1.2.1!
