Re: [Discuss-gnuradio] Building an OOT from the Tutorial

[P C]

Marcus,

There is a distinct possibility I have mucked up the installation.  I 
started with the most straightforward steps.  I am using a Raspberry Pi 
with their GUI that looks like a Windows type GUI.  It has a Add/Remove 
software option and will search for any items I want. I am pretty sure 
it uses apt.

It found GNURadio and a whole host of blocks.  I installed and no 
osmocom blocks were available.  I have the cheapy dongle.  So I went 
back to Add/Remove software and saw further down, GNURadio blocks from 
the OsmoSDR project.  I installed and now I had the block I needed.  
Unfortunately that gave me all kinds of segment faults and other Python 
errors.

So I searched for other ways to install GNURadio and tried those. In all 
likelihood  I have remnants of those other attempts laying all over my 
SD card.

BUT---IN THIS CASE Kyeong Su Shin gets the blue ribbon.  I was including 
the prompt in the command.  I have been banging my head against GNURadio 
so much I think I'm loosing it.  I am now past that step and will get 
back to the rest soon.

Note, if that OutOfTreeModules is obsolete I tried the tutorials but 
they seem to be down right now.

All say, "Unable to connect".

Thanks,
Pete
