redeclaration of enumerator

Hello Experts,

I have two headers "common.h" and "libsomething.h" both define an enumeration called "OK" and neither belong to me (they are from different projects). I need to reference both these headers in one of my own. When I compile I get the following error:

error: redeclaration of enumerator ‘OK’

Is there a way for me to take advantage of the code in both these files?

Thanks

I guess you will have to rename one of them.

As I mentioned neither belong to me, they are part of other projects one opensource and the other commercial.

Change the open source code? OK is a rather bad name on two counts: it is short and without some kind of prefix (in a language without namespaces!), and it is all in uppercase which is a convention normally reserved for macro names.

Do you need both definitions of OK?

If not, something like this might work

Code:

---

#define OK BAH_HUMBUG
#include "common.h"
#undef OK
#include "libsomething.h"

---

If you do need both, then you'll have to create your own small wrapper API which results in you only #including one of the header files at once.
That can get a bit messy if you're not careful.

If you only want say a small part of libsomething.h (say), and most of common.h, then you might also be able to just wrap the parts of libsomething which really interest you.

Also, raise a bug report on both packages telling them about the poor use of generic names like "OK", and the likely conflicts it generates.
