Hi,
I am trying to install new modules into my gnu radio tree. I have MAC
OSX 10.5.5 but on a G4 PPC. Following instructions online that use
MacPorts, I have been able to successfully run built-in scripts and
verify that all required components of GNU radio are working. However,
when compiling and running the example gr-how-to.... I ran into some
interesting problems. First, looking at the output of the make install
I see that the module gets installed in the /opt/local/Library/
Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/
gnuradio directory. When I try to run the simple qa_howto.py script
it fails saying that module howto is no found. Looking at
bash-3.2$ echo $PYTHONPATH
/opt/local/lib/python2.6/site-packages:/usr/local/lib/python2.6/site-
packages
I can solve the problem by moving the installed components under the /
Frameworks/Python.framework/ tree to /usr/local/lib/python2.6/site-
packages/, but that is a hacked up method that whenever I write my
code or change it, I have to worry about copying before I am sure that
the new module is what is going to be used.
So I edited, what I think is the appropriate portion of my ./bashrc
file as follows
export PYTHON_VERSION=`python -V 2>&1 | sed -e 's...@\.@ @2' | awk
'{ print $2 }'`
export PYTHON_ROOT=`which python | sed -e 's@/bin/python@@g'`
export PYTHONPATH=${PYTHON_ROOT}/lib/python${PYTHON_VERSION}/site-
packages
if [ ${PYTHON_ROOT} != "/usr/include" ]; then
export PYTHONPATH=${PYTHONPATH}:/usr/local/lib/python$
{PYTHON_VERSION}/site-packages
fi
export PYTHONPATH=${PYTHONPATH}:/opt/local/Library/Frameworks/
Python.framework/Versions/2.6/lib/python2.6/site-packages <--- added
by me.
However, even this doesnt help if I do a new make install (and now the
$PYTHONPATH includes the directory with the installed files).
So I searched on the gnu radio mailing list, and it appears it has
something to do with multiple versions of python installed. I know
that I had previous installed python and so when I do a which python
bash-3.2$ which python
/opt/local/bin/python
and my $PATH variable is not pointing to where the Macport has
installed python2.6.
echo $PATH
/opt/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/X11R6/
bin
What do I have to change (in the configure files or at a larger scale
on my system) to make sure my make install puts the new module in the
same place the GNU radio is looking at?
Thank you.
regards,
Affan
