IDE Version: RAD Studio 10.1 Berlin
SDK Version : 7.5.0 Build 802 Evaluation Edition

I don´t know what happended, maybe you can help me. Everything was fine and I was able to compile my sample project until now. I reduced the relevant code to this:

.h file:
— begin of file —
#ifndef include_bugH
#define include_bugH

#include “ProsysOPC.UaServer.Nodes.hpp”

#endif
— end of file —

.cpp file:
— begin of file —
#pragma hdrstop

#include “include_bug.h”
— end of file —

And this is the compiler output:
bcc32c command line for “include_bug.cpp”

[bcc32c Error] MsXml2.h(629): elaborated type refers to a typedef
[bcc32c Hint] MSXML2_TLB.hpp(325): declared here
Failed
Elapsed time: 00:00:04.4

This is the relevant line of code in MsXml2.h:
— snippet begin —
#ifndef __DOMDocument26_FWD_DEFINED__
#define __DOMDocument26_FWD_DEFINED__

#ifdef __cplusplus
typedef class DOMDocument26 DOMDocument26; << Line in question
#else
typedef struct DOMDocument26 DOMDocument26;
#endif /* __cplusplus */

#endif /* __DOMDocument26_FWD_DEFINED__ */
— snippet end —
What can I do?

Kind regards,
Guido
