using once.hpp also fails to compile:

<pre> --snip #define BOOST_NO_EXCEPTIONS

#include <boost/thread/once.hpp>

boost::once_flag once = BOOST_ONCE_INIT;

bool initialised = false;

void testOnceInit() {

assert(!initialised); initialised = true;

}

struct ConstructOnce {

ConstructOnce() {

boost::call_once(&testOnceInit, once);

}

};

ConstructOnce first; ConstructOnce second;

type, severity changed

type Bugs → Feature Requests
severity Problem → Not Applicable

Your patches just protect the throw statements, but what would be the behavior of the application with your patches. I think Boost.Threads has not an interface that allows to use it without exceptions, so I will consider this a feature request and not a Bug.

status, milestone changed; cc, resolution set

cc nigels@… added
status new → closed
resolution → duplicate
milestone Boost 1.40.0 → Boost 1.43.0

Marking this as a duplicate of #2100 - thread fails to compile with -fno-exceptions.

The good news is that this is just about resolved in boost svn trunk.
