Re: [Discuss-gnuradio] Problem loading Python block

[Nemanja Savic]

Thank you Martin, I will try that on Monday.

I suppose that I have older version of gr_modtool, cause there is no option -l for selecting language.

My weekend would be maybe perfect If you or anybody else can explain to me why my code won't work, cause I  have more or less copied block structure from grextras.

Nice weekend

For a hier block in Python, do

$ gr_modtool.py add -t hier -l python

You need 3.6.3 to do that.

Also, you'll need a new version of modtool (it usually lags a bit behind
changes in GNU Radio).
