GNU Radio 4.0

Introduction

GNU Radio 4.0 represents a major shift in the framework to allow for new functionality that has required architectural change to allow, such as:

• Modular Runtime Components
• Improved Support of Heterogeneous Architectures
• Support for Distributed Architectures

To see a full description of the proposed features for 4.0, please see GNU_Radio_4.0_Summary_of_Proposed_Features

Getting and Installing

Currently GR 4.0 is not packaged, but can be easily built from source:

A complete list of dependencies can be found in the CI worker build scripts. These include:

• meson-build
• ninja
• jinja2
• gcc (or clang)
• spdlog
• libfmt
• gtest
• pybind11
• python3
• numpy
• soapysdr
• libasound

Ubuntu

sudo apt install libzmq3-dev libspdlog-dev libyaml-cpp-dev libgtest-dev libfmt-dev pybind11-dev python3-dev python3-numpy build-essential ninja-build libfftw3-dev libgmp-dev libgsl0-dev git python3-pip pkg-config libsoapysdr-dev libasound2 portaudio19-dev libad9361-0
pip install meson ninja mako jinja2 pyyaml zmq jsonschema jsonschema-default 

For Ubuntu 22.04, VOLK can be installed from apt

sudo apt install libvolk2-dev 

But for Ubuntu 20.04, we must install VOLK from source

# Install VOLK
mkdir -p /src/build
git clone --recursive https://github.com/gnuradio/volk.git /src/volk --branch v2.4.1
cd /src/build && cmake -DCMAKE_BUILD_TYPE=Release ../volk/ && make && make install && cd / && rm -rf /src/ 

For both 22.04 and 20.04, flatbuffers must be installed from source

# Install Flatc
mkdir -p /src/build
git clone https://github.com/google/flatbuffers.git /src/flatbuffers --branch v2.0.0
cd /src/build && cmake -DCMAKE_BUILD_TYPE=Release ../flatbuffers/ && make && make install && cd / && rm -rf /src/
