This guide was not complete. I am running KUbuntu 15, very stock, and several needed packages were not mentioned, and the git clone commands did not work (Permission denied (public key). So here's some help.

git clone https://github.com/scateu/kalibrate-hackrf.git

./bootstrap fails until you run this:

sudo apt-get install autoconf automake fftw3-dev

but then i get this:

checking for LIBHACKRF... no configure: error: Package requirements (libhackrf) were not met:

No package 'libhackrf' found

Which doesn't make sense, because I do have libhackrf0 and libhackrf-dev installed! Any help?
