Forum: GNU Radio gr-modtool questions

After I do a newmod, how to I add a new block?

when I use gr_modtool.py add <directory-from-newmod>

It simply says no Gnu Radio module found in named directory.

If you're not in the module directory, use '-d <dirname>'.
Otherwise,

$ gr_modtool.py add myblock_ff

..or whatever your block's called.

$ gr_modtool help add

is your friend, and the example on https://www.cgran.org/wiki/devtools
seems OK too.

i did as you mentioned but, it gives me error when i try to add it to
grc as a block.

my steps:1

bynkln@ubuntu:~$ gr_modtool.py create myQpsk
Module directory is "./gr-myQpsk".
Creating directory...
Copying howto example...
Unpacking...
Replacing occurences of 'howto' to 'myQpsk'... Done.
Use 'gr_modtool add' to add a new block to this currently empty module.

2

adding qpsk.py code into __init__.py with hand editing

bynkln@ubuntu:~$ gr_modtool.py add myQpsk
No GNU Radio module found in the given directory. Quitting.
bynkln@ubuntu:~$ cd gr-myQpsk
