[systemd-devel] error: undefined reference to `sd_event_source_unref' while the function exists in source

Sorry for your time.
My last topic is about error on compiling (make and make install) systemd,
and as i said in the last reply, systemd compiling works well now.
So i thought that "compiling failed" topic is in a "closed" status.
That's why i sent mail on another topic (for error on compiling source code which depends on libsystemd) .

Thanks for your advice, i will do it better next time.

As far as I'm aware the sd-event code is not yet exported as a library,
so you'll likely have to compile and link all the sd-event.c code into
your project too.
 
It might help if you explain to the list what "some source code"
actually refers to!
