Re: [Discuss-gnuradio] Simple FM receiver GRC error
That was the error I was getting. I've found that I still get it if I do not start gnuradio-companion in the directory where simple_fm_helper is located. Apparently, that Import block/function is very simplistic and will only import from the directory that companion was started in. -- 73s jim KI6NJF No. If the helper .py file has been copied into $HOME/bin (which gets done by the makefile), *AND* PYTHONPATH includes $HOME/bin you should be golden. Use the starter shell script, which should also be in $HOME/bin: simple_fm_rcv -- Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] Simple FM receiver GRC error
I'm sorry to have to ask more questions. The Simple FM receiver by Marcus Leech would seem to be simple in name only. I'm sure that I have followed the installation instructions to the letter but I still end up with an error as follows: Welcome to GNU Radio Companion 3.5.3.2 Loading: /home/phil/bin/simple_fm_helper.py Error: Start tag expected, '' not found, line 1, column 1 Failure Showing: In case I've missed something important, this is what I did. I opened simple_fm_rcv.grc with gnuradio-companion and there aren't any '' in the file simple_fm_helper.py. -- Regards, Phil ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Phil, I just got simple_fm_rcv working today.
I had to:
open up a terminal
cd to my radio flowdiagram directory - /home/jim/gnu_radio
svn co https://www.cgran.org/svn/projects/simple_fm_rcv
cd to the directory - in my case - /home/jim/gnu_radio/simple_fm_rcv/trunk/
make install
export PYTHONPATH=$PYTHONPATH:/home/jim/bin
then run gnuradio-companion
then open simple_fm_rcv.grc
it works! Before this, I was getting an import error for simple_fm_helper no
matter where I put the simple_fm_helper program or what I set the PYTHONPATH
to.
now each time I run gnuradio-companion or the python variant, I have to run
the export PYTHONPATH=$PYTHONPATH:/home/jim/bin
statement from inside the terminal that I'll start gnuradio-companion from.
{I've not figured out (yet) where Kubuntu 12.04 keeps the .profile or xxx
file that would permanently set the python path and allow me to start
companion from the GUI.}
