The above change will lead to a broken library as the symbol will be missing. Just returning -ENOSYS when libudev is missing sounds reasonable imho. Although I'm more inclined to reverting the patch, unless we get an actual user and an implementation that does not pull the dependency of libudev.
Thanks Emil

I'm not sure it's right using HAVE_LIBUDEV instead of UDEV because currently UDEV is used from .c file but HAVE_LIBUDEV is not.

Sure, it's reasonable to use #if in function.

I'm afraid that I giggled a bit while I read this. Surely you know the difference between udev and libudev, and after a brief inspection of the code, original and newly added, you can see that it differs significantly. Additionally the newly added LIBUDEV_{CFLAGS,LIBS} should be a nice give-away :-)
That aside, I'll send a revert in a second as mentioned previously.
Thanks Emil
