Re: [Discuss-gnuradio] Installing GNURadio On Raspberry Pi

[P C]

Ben,

I am sorry if I came across as cynical and sarcastic.  I didn't mean 
to.  I really wanted to know if anyone could make GNURadio work on a RPi.

I'll be the first to say I know nothing about Linux and Python. However, 
I created the flow graph I need on my windows computer months ago and 
have been trying ever since to get it to work reliably on my RPi.  I 
experienced repeated segment faults, malloc faults, failure to have the 
osmocom block I needed, etc.

Since I asked the question here I have gotten help, very good help and  
still no luck.  In addition I did so many installs and removes my SD 
card is to the point it just needs to be reformatted and rebuilt.

But I did discover during the process that the culprit is the 
osmocom/rtlsdr block.   No matter how I install it, my flow graph just 
won't run when it is enabled.

Luckily during this process, last night, I discovered that I don't need 
the osmocom/rtlsdr block.  I can get the stream from my rtlsdr using the 
command:
rtl-sdr -f xxxx -s xxxx /tmp/aFIFO
where a FIFO is created with mkfifo aFIFO.  Then read the FIFO with a 
file source block.

It might not have as good a SNR as on windows but I think I can adjust 
some filtering and move some gains around and it will be acceptable.

So, I'm off and running to complete my project and I'm not looking back 
(I hope).

Maybe if I need to do this for another project I'll start over. It looks 
like Glen and Marcus are using Ubuntu where as I have been using 
Raspbian.  I'll go that route next time.

Thanks,

Pete
