[Boost-users] [fusion] probably a bug in result_of::join

14 Oct 2009


      This is nearly a copy-paste from the doc (and agrees with intuition): 

#include 
#include 
#include  

void foo() {
  using namespace boost::fusion;
  vector<> v1, v2;
  result_of::join< vector<>, vector<> >::type j = join(v1, v2);
} 

...but it doesn't compile (msvc9, boost 1.40): 

c:\UserTemp\x54209\BoostTests\Any\main.cpp(20) : error C2440: 'initializing' 
: cannot convert from 
'boost::fusion::result_of::join::type' to 
'boost::fusion::joint_view' 

        with
        [
            LhSequence=const boost::fusion::vector<>,
            RhSequence=const boost::fusion::vector<>
        ]
        and
        [
            Sequence1=boost::fusion::vector<>,
            Sequence2=boost::fusion::vector<>
        ]
        No constructor could take the source type, or constructor overload 
resolution was ambiguous
