Hi,
I am new to GNU Radio, so I built a FM receiver to get started on the
journey. I created the following .grc file, and when I clicked
<>, I saw the GUI window pop up and exit immediately. The sound
came out only for less than a second and disappeared as the window sank.
I’ve researched this problem in this forum awhile, and someone suggested
it’s probably due to multiple version of gnuradio installed. But I
cleaned everything related to uhd and gnuradio in my /usr/local
directories, and reinstalled via the script “build-gnuradio”, it still
didn’t work. So could you confirm with me whether this is the reason of
my problem, and if so, where can I check to find the conflicted version?
And what do you suggest me do?
I can do uhd_fft successfully, which opens up a window and never quit.
I am using ubuntu 14.04, usrp b210. I used “build-gnuradio” to install
everything. It turned out that grc is 3.7.6.1, with uhd being 3.8.1
Here’s the output of doing <>. It ended with “DONE”, and
windows quit
