I should point out that there is a copy paste error in the code I sent: boost::fusion::get<0>(b); Regards Daniel Bradburn 2011/10/25 Daniel Bradburn

Hi,

I am trying to do the following:

#include <string>#include #include #include int main(int argc, char* argv[]) { typedef boost::fusion::tuple<int> T1; typedef boost::fusion::result_of::push_back::type T2;

T1 a(0); T2 b(boost::fusion::push_back(a, std::string("")));

boost::fusion::get<0>();

T1 c(boost::fusion::pop_back(b));

return 0;

}

However I get the following compilation errors:

error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

error C2868: 'boost::lazy_disable_if_c::type' : illegal syntax for using-declaration; expected qualified-name

error C2065: 'type' : undeclared identifier

error C2039: 'type' : is not a member of 'boost::fusion::result_of::prior<Iterator>'

Having read the topic here : http://lists.boost.org/Archives/boost/2011/08/184624.php it looks like this is partly due to a bug in the pop_back implementation. Is there a fix for this?

However I would like to know if it is also possible to use boost::fusion::get on the result of push_back?

Best regards
