Side-by-side GNU Radio Modules

Configure

With alternate prefix:

./configure --prefix=/usr/local.op25-latest

Alternate environment

Set up the sub-environment to favour the side-by-side module:

~/bin/setenv.op25-latest

#!/bin/sh

LD_LIBRARY_PATH=/usr/local.op25-latest/lib:$LD_LIBRARY_PATH
PYTHONPATH=/usr/local.op25-latest/lib/python2.7/site-packages/gnuradio:/usr/local.op25-latest/lib/python2.7/site-packages:$PYTHON_PATH
# 'export' is necessary
export SUBENV="op25-latest"

bash -i

Show the sub-environment in the shell prompt:

~/.bashrc

if [ -n "$SUBENV" ]; then
        PS1="\e[1;31m$SUBENV\e[m $PS1"
fi

Python sitecustomize

Inject side-by-side module in gnuradio namespace (sitecustomize is automatically included by interpreter):

Override original op25 in gnuradio, because:

 from gnuradio import op25

would return original op25 installation

/usr/local.op25-latest/lib/python2.7/site-packages/sitecustomize.py

print "Customising for: op25-latest"

import op25
import gnuradio
gnuradio.op25 = op25

Could also:

from gnuradio import op25 as op25_original
...
gnuradio.op25_original = op25_original
