you need openat functions in your libc, what libc you use?

At least 2.9 for working signalfd(2) on all kernels.

Didn't it choke on openat() not being in any header files?  Or did you
("you" == "Pierre") ignore that warning?  :-)

If you can't upgrade glibc, you might be able to get away with just
upgrading the kernel (to get these syscalls' implementation), and
hacking together a bunch of inline functions in your own headers (*at,
signalfd4, inotify related stuff, and maybe one or two more) to make the
syscall manually.

This is generally a bad idea, and is *not* recommended if you can
upgrade glibc, but if it's the only way, it might work...

Ok I finally managed to upgrade my glibc to version 2.10.

But I now have another problem :
