sudo apt-get update
安装依赖项：

2 下载UHD代码库并编译安装
2.1 下载
新建工作目录并克隆代码
cd $HOME
mkdir workarea
cd workarea
git clone https://github.com/EttusResearch/uhd
此处遭遇下载失败，经过多番搜索和尝试，认为根本原因是由于连接速度太慢（通常不超过20k/s），解决方法是利用 gitee 码云从github导入代码库，再从 gitee 克隆到本地，1.8M/s的下载速度，完美解决。
2.2 检出标签
进入代码库路径
cd uhd
查看标签
$ git tag -l
...
release_003_009_004
release_003_009_005
release_003_010_000_000
检出v3.15.0.0版本
git checkout v3.15.0.0
2.3 编译
新建build目录，并编译
cd hostmkdir buildcd buildcmake ../make
此处报错，提示找不到 setuptools ，于是再次安装 python3 setuptools
sudo apt-get install python3-setuptools
再次编译顺利通过。
可通过make test检查编译结果：
$ make test

以下是安装过程：
sudo make install
sudo ldconfig
在 $HOME/.bashrc 文件中最后一行添加环境变量
export LD_LIBRARY_PATH=/usr/local/lib
关闭终端，重启生效，此时安装完毕。
2.5 检查确认
可在没有硬件的情况下通过以下命令检查安装是否正确，若正确将得到类似结果
$ uhd_find_devices
[INFO] [UHD] linux; GNU C++ version 9.3.0; Boost_107100; UHD_3.15.0.HEAD-0-gaea0e2de
No UHD Devices Found
2.6 下载FPGA镜像文件
通过以下命令下载UHD FPGA 镜像文件
sudo uhd_images_downloader
此处报错：
[ERROR] Downloader raised an unhandled exception: HTTPConnectionPool(host='files.ettus.com', port=80): Max retries exceeded with url: /binaries/cache/x3xx/fpga-fde2a94eb/x3xx_x310_fpga_default-gfde2a94e.zip (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7fa7565164c0>: Failed to establish a new connection: [Errno 110] Connection timed out'))
You can run this again with the '--verbose' flag to see more information
If the problem persists, please email the output to: support@ettus.com
待解决…
3 安装GNURadio 3.8.1
3.1 二进制安装
官网推荐直接二进制安装：
sudo add-apt-repository ppa:gnuradio/gnuradio-releases
sudo apt-get update
sudo apt-get install gnuradio
3.2 源码编译安装
如果确有需要，可以使用源码编译安装。
3.2.1 安装依赖项
对具有Python 3支持的GNU Radio v3.8.x，安装以下依赖项：
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
若要安装开发版 (GNU Radio v3.9)则还需要以下依赖项：
sudo apt install pybind11-dev python3-matplotlib
3.2.2 安装Volk
volk（vector optimized library of kernel）是矢量优化库，它可以提高在不同计算平台矢量计算的效率。
Volk项目也是GNURADIO的一个子项目，GNURADIO也依赖这个项目。
cd ~/
git clone https://github.com/gnuradio/volk.git
cd volk
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3 ../
make
make test
sudo make install
sudo ldconfig
3.2.3 安装 GNU Radio
cd
git clone https://github.com/gnuradio/gnuradio.git
cd gnuradio
git submodule update --init --recursive
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3 ../
make
下载速度太慢的话可以从gitee下载，用以下地址替代 github 克隆地址：
https://gitee.com/crown_zxh/gnuradio.git
检查编译结果并安装：
make test
sudo make install
3.2.4 配置连接库环境变量
添加如下环境变量到 $HOME/.bashrc 文件的最末行
export PYTHONPATH=/usr/local/lib/python3/dist-packages:/usr/local/lib/python3/site-packages
3.3 安装完毕
关闭终端重新打开，输入
gnuradio-companion
开启你的新旅程吧!
