How to install

In general on a Debian based distro, the following dependencies are required.

sudo apt install build-essential libtool automake autoconf librtlsdr-dev libfftw3-dev
git clone https://github.com/steve-m/kalibrate-rtl
cd kalibrate-rtl
./bootstrap && CXXFLAGS='-W -Wall -O3'
./configure
make
sudo make install

While the compiler check-up, a similar message may appear: ./configure: line 5120: PKG_CHECK_MODULES(FFTW3, fftw3 >= 3.0)' in this case, you need to install the pkg-config package (apt install pkg-config) and run it again (see above).

On Debian 10 ("Buster"), or Debian 10-based distros, this error may appear (after quite a lot of similar ones) while attempting to link code: /root/kalibrate-rtl/src/usrp_source.cc:150: undefined reference to rtlsdr_set_freq_correction' collect2: error: ld returned 1 exit status`

The file librtlsdr.pchas to be edited. That file is located in /usr/lib/<cpu_type>/pkgconfig/ or /usr/local/lib/pkgconfig/librtlsdr.pc where cpu_type is x86_64-linux-gnu for x86-64 CPUs, arm-linux-gnueabihf for Raspberries and "Raspi compatibles" like for example Orange Pis.

Edit as follows:

prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
