I could not build boost code,
I have sample code, I just wanted to build it. I am trying to send log to a file, unfortunately the init function part does not compile, I posted code and compile error as follows, I just wonder what I did wrong here:
Thanks for your help.
Here is the code I am compiling, boost has setup correctly, I can build main part, it running and output message on the console, I just need to redirect to a file, but I could not build init() function:

I am using boost 1.59.0 at this time, I have compiled the code for both 64 bit.
Does anyone knows what is wrong?

Thanks for your help.
Here is the code I am compiling, boost has setup correctly, I can build main part, it running and output message on the console, I just need to redirect to a file, but I could not build init() function:
#include <boost/log/core.hpp>
#include <boost/log/trivial.hpp>
#include <boost/log/expressions.hpp>
#include <boost/log/utility/setup/file.hpp>
using namespace boost::log;
void init()
{
logging::add_file_log("sample.log");
logging::core::get()->set_filter
(
logging::trivial::severity >= logging::trivial::info
);
}
int main(int, char*[])
{
BOOST_LOG_TRIVIAL(trace) << "A trace severity message";
BOOST_LOG_TRIVIAL(debug) << "A debug severity message";
BOOST_LOG_TRIVIAL(info) << "An informational severity message";
BOOST_LOG_TRIVIAL(warning) << "A warning severity message";
BOOST_LOG_TRIVIAL(error) << "An error severity message";
BOOST_LOG_TRIVIAL(fatal) << "A fatal severity message";
return 0;
}
Here is the compile output:1>------ Build started: Project: testboostLogging, Configuration: Debug x64 ------

Thanks. Close this question here

I added following line:
namespace logging = boost::log;
This makes it to be build.
