Python OOT Block on Windows

GNU Radio
1

Hi,

Is it possible to create an OOT module written in Python to run on
windows without having to compile anything? I am hoping that I can drop
a Python file and a GRC file somewhere and have them just run, seeing as
Python does not need to compile anything.

I have GNU Radio installed with the Ettus binaries, so I am not using
MinGW to compile from source and can’t compile new blocks using MinGW.

Thanks,
Luke

Hi Luke,
Well, yesno. If your python file stands alone, putting it somewhere
python will find it suffices, and there are standard directories to just
drop your xml file defining the GRC block representing that block.
Since 3.7.1 (I thiiiiink…) pure-Python OOTs work well without having
ever been touched by a compiler. Note though that the whole installation
routine depends heavily on the standard GNU Radio build environment,
which will make it a bit hard to actually work without a compiler, or
CMake. Personally, if you can, try to set up a proper development
environment [1]-- it will come in really handy if you decide you want to
build the latest GNU Radio yourself later on or if your signal
processing needs demand C++ blocks at one point.

desirable) components are already set up is the live DVD –

Thanks Marcus,

So I have a Python file that I created using the gr_modtool and tried to
run it, but I get an import error:

Traceback (most recent call last):
File “C:.… …\top_block.py”, line 15, in
import custom
ImportError: No module named custom

Do I need to add anything to the Python file (or remove anything from
the top_block.py file) to allow it to run standalone?

Thanks,
Luke
