I searched for a compiler switch I might be missing but with no luck so I
thought I woud post. I am using the latest version.
When I try to compile the following:
#include <afxctl.h>
void func()
{
int i = 0;
}
I get the following errors:
Error: C:\DM\BIN\..\include\win32\objidl.h(358): forward referenced class
'IUnknown' cannot be a base class
Error: C:\DM\BIN\..\include\win32\objidl.h(615): forward referenced class
'IUnknown' cannot be a base class
Error: C:\DM\BIN\..\include\win32\objidl.h(821): forward referenced class
'IUnknown' cannot be a base class
Error: C:\DM\BIN\..\include\win32\objidl.h(1183): forward referenced class
'IUnknown' cannot be a base class
Thanks!

I just tried it and it works. Perhaps your INCLUDE environment variable isn't set right?

Walter,
This is what I am using:
c:\dm\bin\dmc cctest.cpp -cpp -c -Aa -HO -D_DEBUG=1 -D_MBCS=1 -D_X86_=1 -D_MT=1
-IC:\dm\mfc\INCLUDE -IC:\dm\INCLUDE
CCTest.CPP is:
// cctest.cpp
#include <afxctl.h>
void func()
{
int i = 0;
}
Thanks - Andy

Andy C <Andy_member pathlink.com> Solved: -Aa- and never using the -HO switch allows a compile in both Debug and Release! (IDE does not set -Aa- correctly so I stuck it in sc.ini).
