Need help compiling 64-bit C++ Code in VS2005...

[john.placais]

Hello generous helper!

I am trying to figure out how to port my code from 32-bit VC++ 6.0
to unmanaged C++ 64-bit VS2005. I have found the preprocessor
definition changes and the linker changes, but I get errors compiling,
like:

error C2371: 'size_t' : redefinition; different basic types

I get the feeling that I am doing something horribly wrong, even when I
try to make a "Hello World" program, its not working out for me in
64-bit... Does anyone have an unmanaged C++ VS2005 Project in 64-bit
that does "Hello World" just so I can see how it is done? Thanks!

It seems that somewhere somehow your compiler encounters two conflicting
definitions of 'size_t'. The only place I know where it should exist is
<cstddefor <stddef.h>. You need to post your code so we can try it and
see. A better course of action would be to post to

microsoft.public.vc.language

since that's where they talk VC++ and where they can help you with your
compiler-specific issues. Do post your "Hello world" program, still.

Actually, the type size_t is required to be defined in all of the
following, using the preferred C++ names:

<cstddef>, <cstdio>, <cstdlib>, <cstring>, <ctime>, and <cwchar>.
