Re: [Hapy-users] Msvc compilation errors

[Alex R. <rou...@me...>]

Srinidhi,

 	I am not sure what causes the errors you quoted. It seems to 
be related to the Hapy use of the std_bidirectional_iterator template. 
It is not the first time that supposed-to-be-portable STL construct 
causes compilation troubles. Perhaps my code in PreeKids.h uses 
std_bidirectional_iterator interface the wrong way.

 	Attached is a patch that might help. It changes
 	std::iterator_traits<PreeKidsIterator>
in typedefs to more explicit
 	std::iterator_traits< PreeKidsIterator<Base> >

The patch does not cause compilation problems with GCC 2.95. I do not 
have access to MSVC. Please let me know whether the patch helps in 
your case. I doubt the patch helps, but it does not hurt to try.

 	FWIW, there are many Hapy users building Hapy with MS 
compilers. I wonder if there is some MSVC version compatibility issue 
here? What version do you use?

 	If anybody has better std_bidirectional_iterator knowledge or 
workaround suggestions please chime in!

Thank you,

Alex.
