You don't need to define BOOST_MPL_LIMIT_VECTOR_SIZE if you are using a numbered form ('vector20') -- you can just include the corresponding header directly, e.g. #include "boost/mpl/vector/vector20.hpp"
#include "boost/mpl/vector.hpp" #include "boost/mpl/push_front.hpp"
class X { };
typedef boost::mpl::vector20< X, X, X, X, X, X, X, X, X, X, X, X, X, X, X, X, X, X, X, X > test; typedef boost::mpl::push_front< test, X >::type test2;
This produces a vector with 21 elements; it will work for GCC (and other compilers with some kind of 'typeof') in the next release, however right now to be able to programmatically extend a 'vector' up to N elements you need to include the corresponding "vector(((N+9)/10)*10).hpp" header. In your case above it'll be "vector30.hpp". HTH, -- Aleksey Gurtovoy MetaCommunications Engineering
