Yes. I will cause your OOT blocks to be installed in the same place as
all the other GNU Radio blocks.

Kevin,
It worked! I really appreciate your help!!
Ron,
So that install prefix should be pointing to where I installed gnuradio?

Hi Logan:
I just went through the same process! My new OOT block wasn't
being found. The solution is to add a [grc] segment to the
config.conf file in ~/.gnuradio:
I had to create the .gnuradio directory, then add the simple
two-line [grc] stanza to a new config.conf file:
[grc]
local_blocks_path=/usr/local/share/gnuradio/grc/blocks
This tells grc to look for additional blocks in the stated
directory. So you would do something like:
cd
mkdir .gnuradio
cd .gnuradio
vi config.conf
Then add the two lines above, your OOT block install path may be
different so I'd check it first.
Hope this helps,
Kevin

create a block that multiplies the input values by 2 (very similar
to the guided tutorial example of the square_ff block).
