Boost in doesn't work. Why?

[bogong]

Hello all!

I am trying to run simple Boost example:

// System includes
#include <iostream>
#include <boost/locale.hpp>
#include <boost/log/trivial.hpp>
#include <cassert>
#include <ctime>

// Application includes

// Namespace
using namespace std;
using namespace boost::log;

int main(int inCounter, char *inArguments[]) {

	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";

	cout << "Hello World!" << endl;

	return 0;
}

But at time of compilation I see this:

Undefined symbols for architecture x86_64:

In editor no any errors. Include directory working perfectly. All headers available.

What am I missing?

I would guess your boost libs are for the wrong architecture. But what has this to do with Qt?

[bogong]

@Christian-Ehrlicher I am trying to implement Boost in my Qt application. For now just trying to write tests/examples for researching purpose. The same result when I am trying to implement it into Qt Quick Application.

[bogong]

@Christian-Ehrlicher Just tested architecture - all is OK. At least via lipo:

$ lipo -info libboost_locale.a
Non-fat file: libboost_locale.a is architecture: x86_64
$ lipo -info libboost_log.a
Non-fat file: libboost_log.a is architecture: x86_64

Hi,

Did you check whether you are linking all the logging related boost libraries ?
