Compile error with filter function

Hello,

I've just switched from CodeWarrior 9 to 10 and am getting the
following compile error. It didn't occur with CW 9.

Error : function call '[VoCompApp].NewNavObjectFilterUPP(pascal
unsigned char (*)(AEDesc *, void *, void *, short))' does not match
'NewNavObjectFilterUPP(pascal extern "C" unsigned char (*)(AEDesc *,
void *, void *, short))'

I've declared my filter function as follows:

static pascal Boolean MyFileFilter(AEDesc *theItem, void *info, void
*callBackUD, NavFilterModes filterMode) {...}

I've created the function pointer as follows:

g_FilterProc = NewNavObjectFilterUPP((pascal Boolean (*) (AEDesc *,
void *, void *, NavFilterModes))MyFileFilter);

Any help would be appreciated.

Thanks,

Brian

The error message is saying that your filter function was declared
inside an

extern "C" {


..... declaration here...

}

but the NewNavObjectFilterUPP isn't (or vice versa.)

Since extern "C" declarations nest, you can wrap it around #include's:

extern "C" {
#include <NavServices.h>

}

but you might have to do it in your precompiled header build file
(.pch++) for it to take effect.
