I think it is because you don't use the latest bladerf library - or if
you do, you probably still have an older version left.

By the way, you should get this error while building gr-osmosdr and
not while building gqrx unless you build gqrx before gr-osmosdr, which
is the wrong order.

I had the same build error few days ago when I tried to build
gr-osmosdr in the gqrx/snapshots PPA against somebody elses bladerf
debian package. I have then updated the bladerf library to the latest
git where after everything built fine and is now avaialble through the
gqrx PPA: https://launchpad.net/~gqrx/+archive/snapshots
- though untested by me since I don't have the hardware.
