Re: Help request

[Derek Kozel]

    Hello Vincenzo,
    
    Thank you for the really detailed description of what you've done.
    The original author of gr-gpredict-doppler stopped working on it
    five years ago and so it is incompatible with recent versions of GNU
    Radio.
    
    Happily another community member has updated it themselves. Delete
    your current gr-gpredict-dopler folder and restart using this
    repository.
    https://github.com/ghostop14/gr-gpredict-doppler
    
    Daniel Estevez has also not updated his doppler example, but GNU
    Radio will try to automatically update the flowgraph when you open
    it.
    
    Regards,
    Derek

Hi folks,

This is my first post and I need an help if possible.

Unfortunately it is a while that I am using Linux and in my case UBUNTU.

As I am an amateur radio I ma trying o install some programs for satellite.

I have installed Gnuradio with the following commands:

 

sudo apt install git cmake g++ libboost-all-dev libgmp-dev swig python3-numpy python3-mako python3-sphinx

python3-lxml doxygen libfftw3-dev libsdl1.2-dev libgsl-dev libqwt-qt5-dev libqt5opengl5-dev python3-pyqt5

liblog4cpp5-dev libzmq3-dev python3-yaml python3-click python3-click-plugins python3-zmq python3-scipy

 

sudo add-apt-repository ppa:gnuradio/gnuradio-releases

 

sudo apt-get update

 

sudo apt-get install gnuradio

 

 

I just gave those commands and nothing else, hope is the correct procedure.

After this I have tried to install the Doppler with the following commands:

 

git clone https://github.com/daniestevez/doppler   and then

 

git clone https://github.com/wnagele/gr-gpredict-doppler

 

after this I had gave these commands:

 

 

cd gr-gpredict-doppler

mkdir build

cd build

cmake ..

 

I had to give more command but arrived at the above command I get an error.

I get this:

CMake Error at CMakeLists.txt:35 (find_package):

  Could not find a configuration file for package "Gnuradio" that is

  compatible with requested version "3.7.7".

 

  The following configuration files were considered but not accepted:

 

    /usr/lib/x86_64-linux-gnu/cmake/gnuradio/GnuradioConfig.cmake, version: 3.8.1.0

    /lib/x86_64-linux-gnu/cmake/gnuradio/GnuradioConfig.cmake, version: 3.8.1.0

 

 

Please anybody can help me to solve the problem?

Thanks
