Re: [Discuss-gnuradio] GRC request

[Josh Blum]

Im not a huge fan of the hard-coded directories, i think it might be 
kind of nice to have a data_dir_prefix that would default to whatever 
automake/autoconf says, but also takes queues from an environment 
variable...so

I know this is possible, but I am a bit confused about why. Woulnt it be 
easier to modify $(datadir) via ./configure --datadir=xxx, and use the 
whole automake system for gnuradio? What are you attempting to do, 
making a distributable package?

and because we like one-liners :-)

import os
DATA_DIR = os.environ.get("GRC_DATADIR", @datadir@)
