一、介绍

先前因为需要调试GNURadio 程序缘故，需要实时处理大量数据，每次都会出现突发溢出，所以尝试安装gr-analysis 工具进行离线接收处理。安装过程简单，但中途有小问题耗了一天，特此记录。

Features

Tools for High Sample Rate Recording and Post-Processing in GNURadio

  • metadata_to_csv: Convert metadata to comma-separated value (.csv) format for import into MATLAB, Octave, etc.
  • specrec: High sample-rate recording (~30 MSPS) program with metadata. Scheduled, time-syncronized records with GPSDO. Linux-only as of now.
  • gr_fileman: File manipulation program. Can convert between data formats, cut out a subsection of data, interpolates timestamps, etc. Somewhat like SoX but exploits metadata and timestamps
  • gr_mkheader: Generate headers for data which previously had none
  • gr_fstat: Compute statistics of .sc16 and .fc32 files (mean,var,max,min)
  • read_file_metadata: Display metadata headers in human-readable format
    具体可参考github https://github.com/garverp/gr-analysis#gr-analysis

二、安装

These tools are primarily Linux-based. All tools but specrec should theoretically work, but untested on OSX/Windows.

git clone https://github.com/garverp/gr-analysis
cd gr-analysis
mkdir build && cd build
cmake ../
make
sudo make install
sudo ldconfig

三、问题

1. C++14 报错

我的ubuntu环境是14.04，在安装到第5步时会出现Error，大体内容是不支持C++14环境。搜索之后得知需要gcc 6.0及以上版本，安装过程涉及到ubuntu上gcc的版本切换，很折腾，在这推荐一个博客，一步到位解决！

关键操作：

sudo apt-get install gcc-5 g++-5	//安装gcc-5版本，实测足够

//更新链接
update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 53 \
--slave /usr/bin/g++ g++ /usr/bin/g++-5 \
--slave /usr/bin/gcc-ar gcc-ar /usr/bin/gcc-ar-5 \
--slave /usr/bin/gcc-nm gcc-nm /usr/bin/gcc-nm-5 \
--slave /usr/bin/gcc-ranlib gcc-ranlib /usr/bin/gcc-ranlib-5

升级之后错误解决，进入第6步

2. UHD缺少头文件

编译第6步会提示UHD缺少头文件，因此我又重新安装了一番，折腾好久还是不行。问题如下：
这里写图片描述

碰巧看了github上的issue提交，修改之后成功，很关键的错误。我把提交的issue复制过来了。

With UHD 3.10.2 PyBOMBS compilation fails due to a wrong uhd included header. 
To solve the issue, it is enough to replace 
line 20 of specrec.cpp with
`#include <uhd/utils/thread_priority.hpp>`

按照路径打开 gr-analysis/app/record/specrec.cpp，修改第20行代码为

1
#include <uhd/utils/thread_priority.hpp>

即可。

结果之后编译就能成功了！
