Sun Studio gives errors when comparing ptime using BOOST_CHECK_EQUAL

[Ákos Maróy <akos@…>]

the following source code:

#include <boost/date_time.hpp>
#include <boost/test/unit_test.hpp>

using namespace boost;

void foo() {
    posix_time::ptime time1;
    posix_time::ptime time2;

    BOOST_CHECK_EQUAL(time1, time2);
}

gives a whole bunch of warnings when compiling with the Sun Studio C++ compiler (Sun Studio 12 patch 1 on 64 bit Linux):

it would be nice if it didn't throw warnings

[Gennadiy Rozental]

There is nothing here Boost.Test related. Add '+d' to the command line to avoid warnings (and -g -KPIC while you at it). Otherwise you can check in mailing list, though Idoubt anyone cares about this warning/compiler.

thanks for the tip. though I'm not sure why would anyone not care about this compiler.
