I've updated my programming ambient to VisualStudio 2003 by a few day, but a first !BIG! problem comes in front of me...

While VisualStudio 6.0 with service pack (I not remind what version...) can easily handle sucessive code, the new version of Microsoft compiler generates a pletora of errors with typedefs. Can someone of You help me understanding WHY!?

template
class iResourceManager
{
protected:
typedef std::map< iString, iReference > iResourceMap;
typedef std::map< iString, iReference >::iterator iResourceMapIter;
typedef std::map< iString, iReference >::const_iterator iResourceMapConstIter;
typedef std::map< iString, iReference >::value_type iResourceMapPair;

...

Thanks a lot for any helps!
...and sorry for my bad english skills...

Posting the errors would help, but you can try the following:

  1.  
  2. template <class T>
  3. class iResourceManager
  4. {
  5. protected:
  6. typedef std::map< iString, iReference<T> > iResourceMap;
  7. typedef typename std::map< iString, iReference<T> >::iterator iResourceMapIter;
  8. typedef typename std::map< iString, iReference<T> >::const_iterator iResourceMapConstIter;
  9. typedef typename std::map< iString, iReference<T> >::value_type iResourceMapPair;
  10.

VS 2003 is way stricter (as is 2002) with templates, also a lot closer to the standard than VS6 ever was. You may need to declare the type of the template parameter:

  1.  
  2. template <class T>class iResourceManager
  3. {
  4.   protected:
  5.     typedef std::map< iString, iReference<class T> > iResourceMap;
  6.     typedef std::map< iString, iReference<class T> >::iterator iResourceMapIter;
  7.     typedef std::map< iString, iReference<class T> >::const_iterator iResourceMapConstIter;
  8.     typedef std::map< iString, iReference<class T> >::value_type iResourceMapPair;
  9. }
  10.  


Note the class before using T in the template definition.

First, thanks for your helps!
adding typename to definitions seems to be usefull, as the code is compiled in the right manner.

Now a new problem pops up...

This is a constructor of my sse matrix class: inline iMatrixSSE(__m128 r0, __m128 r1, __m128 r2, __m128 r3);

compiling it VisualStudio gives me this error message: error C2719: "r3": il parametro formale con __declspec(align("16")) non verrą allineato
in inglish something like: "r3": the formal parameter with __declspec(align("16")) will not be aligned

As before, the same code with VisualStudio 6.0 works perfectly...now it don't...

I think the problem is that you try to pass these parameters by-value on the stack, which means it cannot guarantee alignment? (non-aligned data will cause an exception with most SSE operations).
So I guess you should pass them by-reference instead, it should align the variables properly when you define them.
