Re: Fwd: [Bayonne-devel]timespec *, timespec *)' throws different exceptions (compiling commoncpp 1.0.7)

[Federico Montesino Pouzols]

        Oh, I had not had this problem yet, but I have just read a
mail posted to bug-commoncpp whose author seems to complain about the
same issue. The problem comes from the following lines in config.h:

#ifdef HAVE_PTHREAD_NANOSLEEP
#ifndef HAVE_PTHREAD_DELAY
#define HAVE_PTHREAD_DELAY
extern "C" int nanosleep(const struct timespec *rqtp, struct timespec *rmtp);
#define pthread_delay(x) nanosleep(x, NULL)

        I recall we recently added the declaration of nanosleep
because it is missing (or requires the definition of some weird posix
version related symbols) in FreeBSD. However, this declaration is
conflicting with the one in time.h, which difers because of the 'throw
()'. I guess we will have to make an AC_TRY_COMPILE with nanosleep to
see if it is already declared, and declare nanosleep in config.h only
when strictly necessary.
