Thank you all for your help!
As Marcus suggested, by passing the "-DCMAKE_CXX_FLAGS=-ludev" in cmake, I
managed to solve the problem.
I report here the output of the command "pkg-config --static --libs libusb-1.0":
-pthread -lusb-1.0 -lrt
and the output of the command: "ldd lib/libgnuradio-fcd
udev_enumerate_new is called from the latest hidapi code.
Some distros provide a hidapi package. So the actual fcdproplus tries to
detect if an hidapi package is installed. Otherwise it uses the hidapi
code provided with fcdproplus, which uses udev_enumerate_new.
So it would be interesting
Tracing this down; Daniel, could you share what
pkg-config --static --libs libsub-1.0
says?
in your build directory, can you do a
ldd lib/libgnuradio-fcdproplus.so
Greetings, and good night (forgot the time)

Oh indeed, good point!
Sylvain: you're right.
How gr-fcdproplus ends up being able to compile and link is still a mystery to me. I was
expecting a horrible "symbol export forwarding hack" involving libusb, but no:
$>nm -D /lib64/libusb-1.so
U udev_device_get_action
What I find strange is that the symbol error is found at runtime and
not at link-time. That suggest either there is two libudev and the one
used for runtime is different than the one found for link-time, or
that this library was copied over from another system.
Cheers,
Sylvain

If I was forced to make a wild guess I'd probably assume it uses some USB-HID
interface for configuration, and udev for hotplug detection.
I think I'll have the libery of including Mr. Schroer in this discussion :)

I'm a bit conflicted -- the missing symbol looks like it should belong
to libudev and not libusb-versionhell.
This might indicate that you're bound to update libudev,

I use ubuntu 12.04 and libusb-1.0-0-dev
Do you what version of libusb is compatible?
I think that 1.0.9 and newer are compatible.
