Re: [Boost-users] [reflection] Compilation errors

Thanks guys, that solved this problem.

Still I'm having compilation errors. I'm trying to compile the following code:

#include "car.hpp"
#include <boost/extension/extension.hpp>
#include <boost/reflection/reflection.hpp>
#include <boost/reflection/reflector.hpp>

int _tmain(int argc, _TCHAR* argv[])
{
        boost::extension::reflection<car, std::string> car_reflection( "A Car!" );

        return 0;
}

The car class is separated into a header file. The errors have
something to do with the extension namespace. Here are some examples:

1>c:\documents and settings\i64044\my documents\visual studio
2005\projects\reflection\reflection\reflection.cpp(13) : error C3083:
'extension': the symbol to the left of a '::' must be a type
1>c:\documents and settings\i64044\my documents\visual studio
2005\projects\reflection\reflection\reflection.cpp(13) : error C2039:
'reflection' : is not a member of 'boost'
1>c:\documents and settings\i64044\my documents\visual studio
2005\projects\reflection\reflection\reflection.cpp(13) : error C2065:
'reflection' : undeclared identifier
1>c:\documents and settings\i64044\my documents\visual studio
2005\projects\reflection\reflection\reflection.cpp(13) : error C2275:
'car' : illegal use of this type as an expression
1>        c:\documents and settings\i64044\my documents\visual studio
2005\projects\reflection\reflection\car.hpp(15) : see declaration of
'car'
1>c:\documents and settings\i64044\my documents\visual studio
2005\projects\reflection\reflection\reflection.cpp(13) : error C2275:
'std::string' : illegal use of this type as an expression
1>c:\documents and settings\i64044\my documents\visual studio
2005\projects\reflection\reflection\reflection.cpp(13) : error C3861:
'car_reflection': identifier not found

I think the real question is what header files and compiler symbols I
need to use to have the code compiling? The documentation is a little
spares on details.

Thanks,
Christian
