Re: error running the rx_ofdm.grc example.

[Kyeong Su Shin]

Hello Shivika:

This is caused by "OFDM Transmitter" block trying to create a debug log file in a location where you do not have a write permission. A quick workaround would be disabling the "Log Debug Info" feature of the OFDM transmitter block (if you do not need the debug log).

I am not sure what is the proper fix for this (as I do not use GNU Radio on Windows regularly).

Regards,

제목: error running the rx_ofdm.grc example.

 

Hi

When i am trying to run the rx_ofdm.grc example ,i am getting the following error.

C:\Program Files\GNURadio-3.7\gr-python27\python.exe: can't open file 'C:\Program Files\GNURadio-3.7\share\gnuradio\examples\digital\ofdm\rx_ofdm.py': [Errno 2] No such file or directory

I tried to duplicate it and save in a new file to run,but again i got the following error.
