Wild Compile Errors with ptime member
I am running Boost 1.33.0 and compiling wiht MinGW. When I compile
the following source file
=========================
#include "boost/shared_ptr.hpp"
#include "boost/test/test_tools.hpp"
#include "boost/date_time/posix_time/posix_time_types.hpp"
class foo {
public:
foo() {}
~foo() {}
boost::posix_time::ptime mExecutionStart;
};
class foo_test {
foo_test();
~foo_test();
void run();
};
void foo_test::run() {
boost::shared_ptr<foo> testObj(new foo());
BOOST_CHECK_EQUAL(testObj->mExecutionStart,
testObj->mExecutionStart);
};
=================================
I get the (lengthy) compiler error output below. As you can see,
something seems to be trying to log something to an output
stream.
The test compile just fine as long as the BOOST_CHECK_EQUAL()
doesn't reference a boost::posix_time::ptime variables.
Any ideas?

You need an output operator << for the boost::posix_time::ptime to be able to print values in test log. Gennadiy

You need an output operator << for the boost::posix_time::ptime to be able to print values in test log.
Or you can put this line:
BOOST_TEST_DONT_PRINT_LOG_VALUE( boost::posix_time::ptime );
at the file level before the first test that uses ptime. It will indicate
that ptime is unprintable. But any test macro that has the value and try to
print it will print out empty space instead. However, looking at the
Date-Time docs, ptime should have I/O operators. Make sure to #include
