Re: [Discuss-gnuradio] Problem using GRC when executing the grc examples

[Tom Gross]

Makmur,

.bashrc is just a convenient way to set environment variables and
aliases when you open a terminal.

if setting theose environment variables (BOOST_PREFIX and
LD_LIBRARY_PATH) before you run grc from the command line fixes your
problem, then you would want to add them to your .bashrc file.

Your .bashrc should be in your home directory.  It should be writable by you.
