I'm just trying to include the files for the shared_ptr class and keep having problems. I was able to fix a problem with a duplicate definition of 'max' and 'min' (in suffix.hpp, it was conflicting with a file from the SGI STL implementation) I mainly just commented it out, if someone has a better

From: "Joshua" plan on how to fix it I would love to know how to fix it. I have tried Boost 1.28 and 1.29 and still got the same set of errors. In addition to the 'max' and 'min' conflict I am getting these errors : projects\boost_1_28_0\boost\checked_delete.hpp(24) : error C2061: syntax error : identifier 'T' projects\boost_1_28_0\boost\checked_delete.hpp(24) : error C2061: syntax error : identifier 'T' projects\boost_1_28_0\boost\checked_delete.hpp(30) : error C2061: syntax error : identifier 'T' projects\boost_1_28_0\boost\checked_delete.hpp(30) : error C2061: syntax error : identifier 'T' projects\boost_1_28_0\boost\detail\shared_count.hpp(184) : error C2504: 'counted_base' : base class undefined

Looks like the SGI STL has the "helpful"

#define typename

somewhere. Fix this (MSVC usually doesn't need this hack) or change all "typename T" template parameters to "class T".

I was wondering if that would fix the problem, it only seems to be in those 2 locations (that I've found so far). I fixed the Min/Max redefinition problem so I'll do a global replace of typename T to class T when I get back home. The only thing I wonder about is that 'typename' appears to be a reserved word in VC++ (its highlighted blue) so is a direct replacement of 'typename' with 'class' appropriate? I haven't done much indepth template programming experience but spending 5 minutes on google I got this : (exerpt from http://msdn.microsoft.com/msdnmag/issues/02/09/CQA/default.aspx) "Now the compiler knows T::Bletch is a type, not a member name. You can also use <typename T> instead of <class T> in the template definition. The following statements are identical: template<class X>... template<typename X>... This should answer the question." So, yes, that did answer my question :) Isn't the internet grand :) Thanks I'll let you guys know how it goes when I get home (don't have VC++ at work). Joshua.
