Install UHD from source

If you want to use GNU Radio with a USRP, install the UHD package from source using the following instructions, or refer to the [USRP Manual] for other options and Operating Systems. UHD sits at the same level as GNU Radio as an independent driver, which gr-uhd references. So if you want gr-uhd enabled, you FIRST must clone and install UHD.

For this example, we will start in the home directory to parallel the steps in InstallingGR#To_install_system_wide.

cd ~/

The following command line script will install all the required dependencies for UHD:

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 python3-gi python3-gi-cairo gobject-introspection gir1.2-gtk-3.0 libusb-1.0-0 libusb-1.0-0-dev libudev-dev python3-setuptools

Clone the code into your home directory:

git clone git://github.com/EttusResearch/uhd.git

cd ~/uhd

Note: In the following command, change v3.15.0.0-rc3 to some other branch or tag if you want to build a different version.

git tag -l
git checkout v3.15.0.0-rc3

Note: Unlike most build processes, this one builds under the host directory.

cd host
mkdir build
cd build

Note: In the following command, we will use -DCMAKE_INSTALL_PREFIX=/usr/local to install UHD into the same prefix as GNU Radio.

cmake -DCMAKE_INSTALL_PREFIX=/usr/local ../

Note: In the following command, if your computer's CPU has multiple cores, you can use the argument -j# to speed compilation;
e.g., make -j3 will use 3 threads in the build. Specify at least one less than the total number of CPU cores so the system does not appear to 'freeze' during the build. If not specified, then a single thread is used for the build.

make -j3
make test
sudo make install

If you're running Linux, then always do the following command after installing any library:

sudo ldconfig

sudo uhd_images_downloader
cd ~/uhd/host/utils
sudo cp uhd-usrp.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules
sudo udevadm trigger
uhd_usrp_probe
