About my second question:

Now I noticed that I have another program with a name of generic colouriser and when i type grc on the terminal i run this program. Now i uninstall generic colouriser and then type grc again but now i got this message:

  File "/usr/lib/python2.6/email/__init__.py", line 82, in __getattr__
    return getattr(mod, name)
  File "/usr/lib/python2.6/email/__init__.py", line 82, in __getattr__
    return getattr(mod, name)
RuntimeError: maximum recursion depth exceeded

Original exception was:
Traceback (most recent call last):
  File "/usr/bin/grc", line 48, in <module>
    from gnuradio.grc.python.Platform import Platform
  File "/usr/lib/python2.6/dist-packages/gnuradio/grc/python/Platform.py", line 22, in <module>

    from lxml import etree
  File "lxml.etree.pyx", line 188, in lxml.etree (src/lxml/lxml.etree.c:124917)
LookupError: unknown encoding: ASCII

The second question in the first mail is invalid!

Thanks...

Hi everyone,

I am newbie both at gnuradio and linux environment and I am currently working on a project about usrp.
First of all I've installed the gnuradio-3.2.2 and ubuntu 9.04. Then i tried to run the dial tone example.

When i run dial tone example on http://www.gnu.org/software/gnuradio/doc/exploring-gnuradio.html on the terminal
there is nothing wrong, i mean it doesn't give any error messages but i can't hear anything from my computer's
speakers. Do i have to do any extra process to execute the code?

My second question is about the grc. I wanted to use this gui to try some examples. But when i write the terminal
"grc" i got this messages;

address@hidden:~$ grc
Generic Colouriser 1.1

grc [options] command [args]

Options:
-e --stderr    redirect stderr. If this option is selected,
               do not automatically redirect stdout
-s --stdout    redirect stdout, even if -e is selected
-c name --config=name    use name as configuration file for grcat
--colour=word  word is one of: on, off, auto

Is there something wrong with it? How can i open the grc GUI ?

Thanks ...
