“Glibc 2.7 doesn't contain timerfd, signalfd, and eventfd”. I’ve substituted the three wrapper functions that call directly the system call. For instance, <br><br>#include <sys/syscall.h><br>#include <unistd.h><br>
#include <fcntl.h><br>#include <stdint.h><br><br>#ifndef __NR_eventfd2<br>#if defined(__x86_64__)<br>#define __NR_eventfd2 290<br>#elif defined(__i386__)<br>#define __NR_eventfd2 328<br>#else<br>#error "Can't define __NR_eventfd2 for your architecture."<br>
#endif<br>#endif<br><br><br>typedef uint64_t eventfd_t;<br><br>#define EFD_SEMAPHORE 1<br>#define EFD_CLOEXEC 02000000<br>#define EFD_NONBLOCK 04000<br><br>int eventfd(unsigned int, int);<br>int eventfd_read(int, eventfd_t *);<br>
int eventfd_write(int, eventfd_t);<br><br>inline int eventfd_read(int fd, eventfd_t *value)<br>{<br> return (sizeof(*value) == read(fd, value, sizeof(*value))) ? 0 : -1;<br>}<br><br>inline int eventfd(unsigned int initval, int flags) <br>
{<br> return syscall(__NR_eventfd2, initval, flags);<br>}<br><br>inline int eventfd_write(int fd, eventfd_t value)<br>{<br> return (sizeof(value) == write(fd, &value, sizeof(value))) ? 0 : -1;<br>}<br><br>The code just works on local machine. It doesn’t work on the older GLIBC machine and for some reason the GLIBC dependency remains. I put this mark <<<<<<<<< GLIBC DEPENDENCY >>>>>>>>> to show the dependecy.<br>

</div></div>Glibc 2.7 doesn't contain timerfd, signalfd, and eventfd. If your<br>
kernel supports them, I think you can use Sheepdog by defining all<br>
relevant functions and structures, for example, as follows.<br>
<br>
#define __NR_signalfd 282<br>
<br>
int signalfd(int fd, const sigset_t *mask, int flags)<br>
{<br>
return syscall(__NR_signalfd, fd, mask, flags);<br>
}<br>
<br>
<br>
Thanks,<br>
