[bin zan]

Hi Eric, 
    Thank you I got it.  I am also trying to study the c++ examples under ../gnuradio/usrp2/host/apps/... ( My objective is to write a channel switching apps in C++). However, when I run  ./rx_streaming_samples -f 2.45G, it doesn't output anything when I run ./tx_samples at the sender side ( I only see one c++ execute file looks like transmit something under that directory).  Please advise which files I should start with.            


Thank you,
Bin Zan
Winlab, Rutgers.

Bin,

The QA code won't run unless you type

 $ make check

This has to do with how a bunch of environment varibles are
manipulated to allow us to test (QA) non-instatlled code.

You can use your new block after

 $ make install

but you'll need to ensure that your PYTHONPATH includes the path where
you installed the new code.  This is usually something like:

 $ export PYTHONPATH=<prefix>/lib/python<ver>/<site-or-dist>-packages
