Hello,

I am trying to setup a "simple" elapsed timer abstraction to hide the boost::timer::cpu_timer concern.

However, I am finding that the usage example illustrated here does not compile, or I am not including something I need to include (more likely).

http://www.boost.org/doc/libs/1_53_0/libs/timer/doc/cpu_timers.html#using-cpu_timer

//Apparently something like this works with my toolchain. Not sure about the illustration. Probably a language standards difference.

elapsed_timer::nanosecond_type const elapsed_timer::elapsed() {

    //The auto type exposes system and user. Not sure why.
    auto elapsed_times = m_timer.elapsed();
    //Result elapsed time is system plus user.
    return elapsed_times.system + elapsed_times.user;
}

FWIW, I am building with Sourcery CodeBench which I believe is GCC 4.7.2 toolchain.

Might there be more complete working examples I can draw from?

Thank you...
