IDL trouble (patch: adding IEnumShellItems interface declaration.)

[David Hedberg]

Hello everyone,

I'm having some trouble with this simple patch. Specifically, it breaks compiling of dlls/actxprxy, producing the message:

*****
../../tools/winegcc/winegcc -m32 -B../../tools/winebuild --sysroot=../.. -fasynchronous-unwind-tables -shared ./actxprxy.spec usrmarshal.o   actxprxy_activscp_p.o actxprxy_comcat_p.o actxprxy_docobj_p.o actxprxy_hlink_p.o actxprxy_htiframe_p.o actxprxy_objsafe_p.o actxprxy_ocmm_p.o actxprxy_servprov_p.o actxprxy_shobjidl_p.o actxprxy_urlhist_p.o   dlldata.o  -o actxprxy.dll.so  -luuid -loleaut32 -lole32 -lrpcrt4 -lkernel32 -lntdll  ../../libs/port/libwine_port.a  -L/usr/local/valgrind-svn/lib
actxprxy_shobjidl_p.o: In function `IEnumShellItems_RemoteNext_Stub':
/home/david/Projects/wine/git/dlls/actxprxy/actxprxy_shobjidl_p.c:6507: undefined reference to `IEnumShellItems_Next_Stub'
actxprxy_shobjidl_p.o:(.data.rel.ro+0xf0): undefined reference to `IEnumShellItems_Next_Proxy'
*****

It compiles if I remove the [call_as] attribute, but I guess that would kind of break the interface. Any obvious mistakes in the patch, or grammar not supported by widl?

Thanks,
David

You need to add an implementation of IEnumShellItems_Next_Proxy/Stub  
to usrmarshal.c

Huw.
