Re: [Boost-users] [Fusion] How to join more than two sequences

The attachment shows my try; however, it fails to compile with the error:

fold_join.cpp:87:47: instantiated from here /home/evansl/prog_dev/boost-svn/ro/trunk/boost/fusion/support/detail/category_of.hpp:15:38: error: 'const boost::fusion::joint_view&, boost::fusion::vector&>&' is not a class, struct, or union type

Anyone have an idea what's wrong?

Using Christopher Schmidt's variadic fusion: http://svn.boost.org/svn/boost/sandbox/SOC/2009/fusion/ solves problem. With the attached and variadic fusion, output is: v1=(tu<1>(100) tu<1>(b) tu<1>(300.1)) v2=(tu<2>(100) tu<2>(b) tu<2>(300.1)) v3=(tu<3>(100) tu<3>(b) tu<3>(300.1)) fold(vv,state0,join_ftor())=(tu<1>(100) tu<1>(b) tu<1>(300.1) tu<2>(100) tu<2>(b) tu<2>(300.1) tu<3>(100) tu<3>(b) tu<3>(300.1))
