Adding #include <iostream> fixes this problem.
What file did you add the include to? I'm trying to get by with <iosfwd> and <ios> wherever possible.
I added it to my Test program. I don't know what the problem is at this point, but here is the test case. If you leave #include <iostream> commented, compile with g++34 fails, but uncomment and it's OK. #include <iostream> #include <boost/io/stream_facade.hpp> #include <vector> #include <string> namespace io = boost::io; #include <vector> #include <boost/io/concepts.hpp> // sink struct vector_sink : public io::sink { vector_sink(std::vector<char>& _vec) : vec(_vec) { } void write(const char* s, std::streamsize n) { vec.insert(vec.end(), s, s + n); } std::vector<char>& vec; }; std::vector<char> F () { std::vector<char> v; vector_sink s (v); io::stream_facade<vector_sink> out(s); out << "hello"; out.close(); return v; } int main() { F(); }
