GNU Radio的安装

介绍下GNU Radio的安装。

进入GNU Radio的官网http://gnuradio.org/redmine/projects/gnuradio，进入wiki目录，在content中选择Build GNU，然后根据你的操作系统选择，我的ubuntu。

安装需求：

• Development Tools (need for compilation)
  • g++
  • git
  • make
  • autoconf, automake, libtool
  • sdcc (from "universe"; 2.4 or newer)
  • guile (1.6 or newer)
  • ccache (not required, but recommended if you compile frequently)

• Libraries (need for runtime and for compilation)
  • python-dev
  • FFTW 3.X (fftw3, fftw3-dev)
  • cppunit (libcppunit and libcppunit-dev)
  • Boost 1.35 (or later)
  • libusb and libusb-dev
  • wxWidgets (wx-common) and wxPython (python-wxgtk2.8)
  • python-numpy (via python-numpy-ext) (for SVN on or after 2007-May-28)
  • ALSA (alsa-base, libasound2 and libasound2-dev)
  • Qt (libqt3-mt-dev for versions earlier than 8.04; version 4 works for 8.04 and later)
  • SDL (libsdl-dev)
  • GSL GNU Scientific Library (libgsl0-dev >= 1.10 required for SVN trunk, not in binary repositories for 7.10 and earlier)

• SWIG (1.3.31 or newer required)
  • Edgy or previous: requires installation from source
  • Feisty or newer: use the standard package install (swig)

• QWT and QWT PLot3d libraries (optional for Qt Gui)

• Polyphase Filter Bank examples
  • for the examples in gnuradio-examples/python/pfb to work you need to install python-scipy, python-matplotlib, and python-tk

• Other useful packages
  • doxygen (for creating documentation from source code)
  • octave (from "universe")

根据ubuntu的版本不同安转的方法不同。我的电脑是ubuntu10.04升级至11.04，按照介绍可以直接运行

sudo apt-get -y install libxi-dev libqt4-opengl-dev

但是后来发现还是缺少很多安转包，因此建议按照10.04的方法安转所有的包

sudo apt-get -y install libfontconfig1-dev libxrender-dev libpulse-dev swig g++ automake autoconf libtool python-dev libfftw3-dev \
libcppunit-dev libboost-all-dev libusb-dev fort77 sdcc sdcc-libraries \
libsdl1.2-dev python-wxgtk2.8 git-core guile-1.8-dev \
libqt4-dev python-numpy ccache python-opengl libgsl0-dev \
python-cheetah python-lxml doxygen qt4-dev-tools \
libqwt5-qt4-dev libqwtplot3d-qt4-dev pyqt4-dev-tools python-qwt5-qt4

接下来就可以下载安装GNU Radio了。首先安转个下载工具git。命令：sudo apt-get install git

然后开始下载gnuradio

git clone http://gnuradio.org/git/gnuradio.git
下载完成后就可以在当前目录下看到gnuradio的问价夹了。进入目录，依次执行如下命令

./bootstrap
./configure
make

注意：运行./configure的时候会发现出现如下错误：

The following components were skipped either because you asked not
 to build them or they didn't pass configuration checks:

 gcell
 gr-gcell
 gr-comedi
 gr-uhd
根据查阅资料 gcell和gr-gcell这两个包是IBM的内核才需要的。而gr-uhd是使用uhd才需要的，因此需要安装的包为gr-comedi，命令如下：
sudo apt-get install libcomedi0
最后make后还是有以下错误：
**
GLib-GIO:ERROR:/build/buildd/glib2.0-2.28.6/./gio/gdbusconnection.c:2279:initable_init: assertion failed: (connection->initialization_error == NULL)
Aborted

==================

==================
make[6]: *** [check-TESTS] 错误 1
make[6]:正在离开目录 `/usr/gnuradio/gr-qtgui/python'
make[5]: *** [check-am] 错误 2
make[5]:正在离开目录 `/usr/gnuradio/gr-qtgui/python'
make[4]: *** [check] 错误 2

make[2]: *** [check] 错误 2
make[2]:正在离开目录 `/usr/gnuradio/gr-qtgui'
make[1]: *** [check-recursive] 错误 1
make[1]:正在离开目录 `/usr/gnuradio'
make: *** [check] 错误 2

上面出现那个错误，我上网找了很多都没有解决，怀疑是我的电脑的ubuntu版本的问题。于是放弃了修改的想法后直接重装了我的ubuntu操作系统10.10的版本（注：前面安装的环境是在ubuntu10.10的版本升级至11.04后的），安装好后重新依照上面的步骤安装成功了。

最后执行gnuradio-companion测试成功与否的时候弹出个错误提示的对话框："Cannot import gnuradio. Are your PYTHONPATH and LD_LIBRARY_PATH set correctly?"意思大概是 PYTHONPATH和 LD_LIBRARY_PATH两个的路径没有设置正确。于是执行以下命令（参考网站：http://lists.gnu.org/archive/html/discuss-gnuradio/2011-04/msg00167.html）：

export PATH=$PATH:/usr/local/bin

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig

export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.6/site-packages

然后再执行gnuradio-companion的时候就出现了一个窗口，至此，gnu radio安装就成功了！
