Hi all!
Hi Zaufi,
I have a problem compiling the following simple program without defining BOOST_MPL_NO_PREPROCESSED_HEADERS. Though obviously there are preprocessed headers in boost/mpl/list/aux_/preprocessed/plain. The problem seems to be in compiler-specific preprocessed header (for example boost/mpl/aux_/preprocessed/gcc/list.hpp) where list is defined with 10 arguments regardless of BOOST_MPL_LIMIT_LIST_SIZE value.
In short, it's this way by design. As you have found out, BOOST_MPL_LIMIT_LIST_SIZE takes effect only if you disable preprocessed headers.
---{boost_list.cc} --------------------------------------------- // # define BOOST_MPL_NO_PREPROCESSED_HEADERS # if !defined(BOOST_MPL_LIMIT_LIST_SIZE) || (BOOST_MPL_LIMIT_LIST_SIZE < 20) # undef BOOST_MPL_LIMIT_LIST_SIZE # define BOOST_MPL_LIMIT_LIST_SIZE 20 # endif #include <boost/mpl/list.hpp> typedef boost::mpl::list< int, int, int, int, int , int, int, int, int, int , int, int, int, int, int
my_list; int main() { my_list l; return 0; }; ---------------------------------------{end of boost_list.cc}---
any suggestions??
Use numbered list forms, e.g.: #include <boost/mpl/list/list20.hpp> typedef boost::mpl::list15< int, int, int, int, int , int, int, int, int, int , int, int, int, int, int > my_list; int main() { my_list l; return 0; } HTH, -- Aleksey Gurtovoy MetaCommunications Engineering
