Gr-modtool questions

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

when I use gr_modtool.py add

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

If you’re not in the module directory, use '-d '.
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

[email protected]:~$ gr_modtool.py create myQpsk
Module directory is “./gr-myQpsk”.

Replacing occurences of ‘howto’ to ‘myQpsk’… Done.
Use ‘gr_modtool add’ to add a new block to this currently empty module.

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