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. Thanks for the report. Let me know if it works with the above patches. Jonathan

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(); }

<snip> Okay, I think I've found the problem. Somehow, I didn't include <istream> and <ostream> in <boost/io/stream_facade.hpp> (I probably erased them at some point by mistake.) Also, I stuck includes for <iostream> all over the place for debugging, and forgot to remove them. Maybe this is why the problem is just showing up now. Try adding the includes to stream_facade, and removing the iostream include in your sample. Best Regards, Jonathan
