more fun with MySQL cluster (actually C++)
Thanks to jperkin@ for the hint about using embedded boost.
That worked quite nicely. Now onto the next problem...
MySQL cluster is building nicely on my -current development
box, but it fails to build on my -9 pbulk box, like so:
-----
/tmp/databases/mysql-cluster/work/mysql-cluster-gpl-8.0.21/mysys/kqueue_timers.cc: In function 'void* timer_notify_thread_func(void*)':
/tmp/databases/mysql-cluster/work/mysql-cluster-gpl-8.0.21/mysys/kqueue_timers.cc:72:50: error: invalid static_cast from type 'intptr_t {aka long int}' to type 'my_timer_t*'
timer = static_cast<my_timer_t *>(kev.udata);
^

EV_SET(&kev, timer->id, EVFILT_TIMER, EV_ADD | EV_ONESHOT, 0, time, timer);
^
gmake[2]: *** [mysys/CMakeFiles/mysys_objlib.dir/build.make:1291: mysys/CMakeFiles/mysys_objlib.dir/kqueue_timers.cc.o] Error 1
-----
On the -9 box, kev.udata (from <sys/event.h>) is defined as intptr_t,
but on -current, kev.udata is defined as void *. With the EV_SET,
the error has to do with the last argument. On the -9 box, it is
defined as intptr_t, but on -current, it is defined as void *.
I don't do C++. The code in question looks like:
-----
if (kev.filter == EVFILT_TIMER) {
timer = static_cast<my_timer_t *>(kev.udata);
-----
and
-----
int my_timer_set(my_timer_t *timer, unsigned long time) {
struct kevent kev;
EV_SET(&kev, timer->id, EVFILT_TIMER, EV_ADD | EV_ONESHOT, 0, time, timer);
return kevent(kq_fd, &kev, 1, NULL, 0, NULL);
}
-----
Any hints on what I can to do make this work on both -9 and -current?
