编译、编写自己的信号处理模块.doc

编译、编写自己的信号处理模块珠海：叶少聪我们在编写USRP模块的时候，一般都是使用GNU RADIO模板，把模板修改一个名字，然后在函数中编写自己的程序，这样就可以独立运行了，但是目前的GNU RADIO模板是3.3.0版本，这个版本增加了CppUnit测试代码，目录结构也跟以往不太一样，刚开始的时候，修改还真有困难，今天做了一个小实验，记录了这次使用模板的全过程：解压3.3版本的代码到目录中，并将目录改成自己需要的名称linux-3a23:/home/shaocong_ye/project # gzip -c gr-howto-write-a-block-3.3.0.tar.gz linux-3a23:/home/shaocong_ye/project # tar -vxf gr-howto-write-a-block-3.3.0.tar linux-3a23:/home/shaocong_ye/project # mv gr-howto-write-a-block-3.3.0 mathbaselinux-3a23:/home/shaocong_ye/project # cd mathbase然后删除多余的文件linux-3a23:/home/shaocong_ye/project/mathbase # rm lib/howto_square2_ff.h linux-3a23:/home/shaocong_ye/project/mathbase # rm lib/howto_square2_ff.cc linux-3a23:/home/shaocong_ye/project/mathbase #
