ubuntu – GNU-RADIO – cmake could not find MPIR


I’m trying to get a RTL-SDR source block (or osmo sdr, since they both work) in GNU Radio, and it apparently must be obtained via the following command lines:

git clone git://git.osmocom.org/gr-osmosdr
cd gr-osmosdr/

mkdir build
cd build/
cmake ../

I do as suggested, but when I run the last line I get the following error

No package 'mpir' found

Among others:

Checking for module 'fftw3f >= 3.0'
Found fftw3f , version 3.3.8
 Found FFTW3f: /usr/lib/x86_64-linux-gnu/libfftw3f.so

  Cannot find source file:

CMake Error at lib/CMakeLists.txt:30 (add_library):
  No SOURCES given to target: gnuradio-iqbalance

CMake Generate step failed.  Build files cannot be regenerated correctly.

I suspect I might be missing some dependencies but I can’t understand what they are or how to get them. Thanks for any help


Okay I got it!

This guy goes over the required libraries


I was missing swig, and afterwards I was also missing liborc-0.4-dev

They can be installed via:

sudo apt-get install swig
sudo apt install liborc-0.4-dev

Please note that despite helping my case in particular, this video predates the release of GNU Radio 3.8 by several years, and really does not reflect GNU Radio’s current requirements.
