Hi I want to use boost::variant with types more than 50. Until now I was using boost::variant with types up to 50 like this : #define BOOST_MPL_CFG_NO_PREPROCESSED_HEADERS #define BOOST_MPL_LIMIT_LIST_SIZE 50 #define BOOST_MPL_LIMIT_VECTOR_SIZE 50 #include <boost/variant.hpp> However , now if I change BOOST_MPL_LIMIT_LIST_SIZE and BOOST_MPL_LIMIT_VECTOR_SIZE to 100 it gives me compiler errors: Cannot open include file: 'boost/mpl/list/list100.hpp': No such file or directory So is 50 the maximum limit of types that can be put in the variant ? Also it seems that the maximum limit of types for vector fusion is 50, and can't increase that, and I want to have fusion vector for more than 50. Is this possible.
