Almost working

The revised build-gnuradio.sh produced no errors on my Fedora 14
installation. It does handle the changes to the web site holding the
FPGA
and firmware, so I did not need to append /old to the web link in the
script
anymore. None of the errors from yesterday popped up at all. The GRC
programs show the right icons now. When I try to run any of them, I
receive
the error

“Cannot import gnuradio. Are your PYTHONPATH and LD_LIBRARY_PATH set
correctly?”

I read a bunch about this problem this morning and tried the following.

python -c “import sys; print sys.path”

All of the /python2.7/site-packages seem to be in there already, but I
also
did

export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/site-packages

This did not add anything to PYTHONPATH when I examined it, so I think
that
is already set correctly.

Next I did

export LD_LIBRARY_PATH="/usr/local/lib:/usr/lib:$LD_LIBRARY_PATH"

These were the steps I found in previous discussions.

I still receive the same error message when I try to run any of the GRC
programs.

When I do

echo ${LD_LIBRARY_PATH}

the list does include /usr/local/lib and /usr/lib

I set up a custom script in /etc/profile.d with the following

export PYTHONPATH="/usr/local/lib/python2.7/site-packages"

export LD_LIBRARY_PATH="/usr/local/lib:/usr/lib"

I verified that these values were present using

echo ${PYTHONPATH} and

echo ${LD_LIBRARY_PATH}

GRC still gives the same error, and more confusingly, my working
installation on Ubuntu shows blank lines with the above echo commands.

It also seems to me that these path variables need to point to lots more
places. I will keep reading.

Sorry for not being more familiar with Linux.

Can someone give me advice on addressing the error presented by GRC for
Fedora 14?

Thanks!

You shouldn’t need to do anything to LD_LIBRARY_PATH.

But on x86_64 systems, Fedora uses
/usr/local/lib64/python2.7/site-packages

So, if you’re on a x86_64 system on Fedora, you’ll need to set your
PYTHONPATH to point to /usr/local/lib64/python2.7/site-packages
