[Discuss-gnuradio] installing new modules

[Affan Syed]

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 'address@hidden@ @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.

Affan
