[Discuss-gnuradio] Building an OOT from the Tutorial

[P C]

I'm having a problem following the Tutorial at:

https://wiki.gnuradio.org/index.php/OutOfTreeModules

At the step where it says, "Creating the files", as instructed, I type 
the line:

"gr-howto % gr_modtool add -t general -l cpp square_ff"

But I get:

"bash: gr-howto: command not found"

I did some searching and found:

https://www.scribd.com/document/375870432/OOT-Tutorial

which said to use:

"gr-howto$ gr_modtool add -t general square_ff" But I get the same 
results. I found this link from 2013 on this list that I am sure is 
obsolete: 
https://lists.gnu.org/archive/html/discuss-gnuradio/2013-01/msg00357.html 
I also tried: 
https://sites.google.com/a/microembedded.com/gnuradio/outoftreemodules 
Where it said to use:
|"~/tmp % gr_modtool.py create howto" I guess I have to resort to 
bothering you folks. Where can I find an example of how to build an OOT 
for dummies? Thanks, Pete |
