compilation error: boost::local_time::local_microsec_clock::local_time()

[dobrov0@…]

just simple call: boost::local_time::local_microsec_clock::local_time()

produces compilation error:

/usr/include/boost/date_time/microsec_time_clock.hpp:116:

error: no matching function for call to

'boost::local_time::local_date_time_base<boost::posix_time::ptime, boost::date_time::time_zone_base<boost::posix_time::ptime, char>

::local_date_time_base(boost::gregorian::date&, boost::posix_time::time_duration&)'

platform ubuntu linux 10.10 x64 compiler: gcc 4.4.5 boost ver: 1.42

I have information from other party that the same problem occurs under MS Windows, with visual studio and boost 1.44

[Katie Chan]

Yes, this is a problem with Visual Studio as well.

Note that the same bug occur when calling:

boost::local_time::local_sec_clock::local_time();

[Manish Mulimani <manish.mulimani@…>]

It works with posix time:

#include <boost/date_time/posix_time/ptime.hpp>

#include <boost/date_time/microsec_time_clock.hpp>

#include <boost/date_time/local_time/local_time.hpp>

int main(int argc, char *argv[]) {

std::cout << boost::date_time::microsec_clock<boost::posix_time::ptime>::local_time() << std::endl; return 0;

}

However as reported in bug, it does not work with local time. There is no overloaded constructor of boost::local_time::local_date_time_base, with following prototype: local_date_time_base(date_type,time_duration_type).

There are 3 parameterized constructors defined: i> local_date_time_base(utc_time_type, boost::shared_ptr<tz_type>) ii> local_date_time_base(date_type, time_duration_type, boost::shared_ptr<tz_type>, bool) iii> local_date_time_base(date_type, time_duration_type, boost::shared_ptr<tz_type>, DST_CALC_OPTIONS)
