MSVC 2003 doesn't see any definitions from a nested include file
- by ezpresso
I have a piece of code with COM class declaration as follows:
#include "PathTypes.h"
MIDL_INTERFACE("552C7555-0555-4444-BA86-56CF39AAFFFF")
IPathCalc : public IUnknown
{
virtual HRESULT STDMETHODCALLTYPE GetLocation(
/* [retval][out] */ GeoLocation* pLoc) = 0;
virtual HRESULT STDMETHODCALLTYPE SetLocation(
/* [in] */ GeoLocation* pLoc) = 0;
...
};
Below is the contents of PathTypes.h file:
#if !defined(PATHCALC_TYPES_INCLUDED)
#define PATHCALC_TYPES_INCLUDED
#include "libastro/AstronomyStructs.h"
#endif
And the libastro/AstronomyStructs.h from an external cross-platform library:
#ifndef _ASTRONOMY_STRUCTS_INCLUDED
#define _ASTRONOMY_STRUCTS_INCLUDED
typedef struct {
double lattitude;
double longitude;
} GeoLocation;
...
#endif /* _ASTRONOMY_STRUCTS_INCLUDED */
When I'm trying to build this code with g++ everything goes well. That's not the case with MSVC 2003 which returns error C2061: syntax error : identifier 'GeoLocation'.
Seems like MSVC doesn't "see" the definitions from the libastro/AstronomyStructs.h file. When I replace #include "PathTypes.h" with #include "libastro/AstronomyStructs.h" the code compiles without errors.
How to make MSVC 2003 to actually "see" the definitions from the nested include files?
