Ubuntu18.04安装GnuRadio（gr-iio） - 文章

今天在安装gr-iio && Gnuradio的过程中遇到一些问题，遇到了如下报错：

CMake Warning at CMakeLists.txt:90 (find_package):
  By not providing "FindGnuradio.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Gnuradio",

  Add the installation prefix of "Gnuradio" to CMAKE_PREFIX_PATH or set
  "Gnuradio_DIR" to a directory containing one of the above files.  If
  "Gnuradio" provides a separate development package or SDK, be sure it has
  been installed.

难搞，经过一番摸索后发现问题出现在Ubuntu，主要原因是18.04默认安装的GnuRadio是3.7版本，如何安装3.8版本呢？直接看了官网教程：https://wiki.gnuradio.org/index.php/UbuntuInstall

由于是Ubuntu18，所以先执行以下命令：

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

安装完成依赖以后依次执行如下命令：

sudo add-apt-repository ppa:gnuradio/gnuradio-releases
sudo apt-get update
sudo apt-get install gnuradio

这样gnuRadio3.8.2就安装完成咯。

安装完成以后，执行如下命令：

git clone https://github.com/analogdevicesinc/gr-iio.git
cd gr-iio
cmake .
make 
sudo make install
cd ..
sudo ldconfig

就顺利安装gr-iio了。
