Lastly sorry with the spam, is an urgent matter.

FULL CODE(POC):

#include <boost/thread/thread.hpp>
#include <boost/thread/xtime.hpp>
#include <iostream>

struct thread_alarm
{
thread_alarm(int secs) : m_secs(secs) { }
void operator()()
{
boost::xtime xt;
boost::xtime_get(&xt, boost::TIME_UTC);
xt.sec += m_secs;

boost::thread::sleep(xt);

std::cout << "alarm sounded..." << std::endl;
}

int m_secs;
};

int main(int argc, char* argv[])
{
int secs = 5;
std::cout << "setting alarm for 5 seconds..." << std::endl;
thread_alarm alarm(secs);
boost::thread thrd(alarm);
thrd.join();
}

ATTEMPT:

g++ -lcurl -lboost_thread -lboost_date_time -lpthread -pthread d.c -o app
/tmp/ccLh0FfM.o: In function `boost::thread::sleep(boost::posix_time::ptime
const&)':
d.c:(.text._ZN5boost6thread5sleepERKNS_10posix_time5ptimeE[boost::thread::sleep(boost::posix_time::ptime
const&)]+0xd): undefined reference to
`boost::this_thread::sleep(boost::posix_time::ptime const&)'
collect2: ld returned 1 exit status

Much thanks in advance with this nasty issue.
