Yes, I just tried with the following code which is not as minimal as it
could be (it the headers includes a lot other headers) but it generate the
same error in an empty project (generated with CMake) Note that I upgraded
to Boost Log V2 in the same time than Boost from v1.52 to v1.53. The
problem seem related to Phoenix as stream is just a typedef if I understand
the code correctly. I added the compilation error log in case the problem
comes from something I've setup:


#include <boost/log/expressions/formatters.hpp>
#include <boost/log/expressions/formatters/stream.hpp>
#include <boost/log/sinks.hpp>

namespace logattr
const auto MODULE_NAME = "ModuleName";
const auto TIMESTAMP = "TimeStamp";

int main()

namespace blog = boost::log;
namespace expr = blog::expressions;

const auto FORMAT_MODULE_NAME = expr::attr< std::string >(
logattr::MODULE_NAME );
expr::format_date_time<boost::posix_time::ptime>( logattr::TIMESTAMP,
"%Y-%m-%d %H:%M:%S" );
const auto FORMAT_MESSAGE = expr::message;

const auto a = expr::stream << FORMAT_TIMESTAMP; // compiles
const auto c = expr::stream << FORMAT_MODULE_NAME; // compiles
const auto d = expr::stream << FORMAT_MESSAGE; // error: no operator "<<"
matches these operand
const auto e = expr::stream << "test"; // error: no operator "<<" matches
these operand
const auto f = expr::stream << std::string("test"); // error: no operator
"<<" matches these operand

return 0;
