Thanks…

From the looks of this, I’m guessing that you’ve installed both the
debian package and one of the tarballs or source from git.

Remove the debian GR package, but leave the rest of the dependencies,
then in the GR source directory,

$ make distclean
$ ./bootstrap && ./configure && make && make check
$ make install (maybe $ sudo make install)

Hi Eric,
Thank you for your guide, I just performed your specified step, but now
I am
getting the screen with this msg:

"
*The following GNU Radio components have been successfully configured:

You my now run the make command to build these components.

The following components were skipped either because you asked not
to build them or they didn’t pass configuration checks:

gcell
gr-gcell
gr-audio-jack
gr-audio-osx
gr-audio-portaudio
gr-audio-windows
gr-comedi
gr-wxgui
gr-qtgui
gr-utils
grc

These components will not be built.

Configured GNU Radio release 3.3git-579-gf6a77079 for build.*

should I perform the make command or I have to install every components,
please reply I am waiting for your green signal

This is fine, but if you want any of the GUI’s (and common apps, such
as usrp_fft) you’ll need to install the dependencies for wxpython.

I think you need:

$ apt-get install wx-common python-wxgtk2.8

But take a look at

http://vps.gnuradio.org/redmine/wiki/gnuradio/UbuntuInstall

for the details on Ubuntu.

Hi Eric, the same problem again, don’t know what went wrong, I followed every step as per you

If you’re getting the same message as below, then you have the same
problem and have failed to remove the Ubuntu package, or at some time
in the past you have installed GR into /usr both and /usr/local.

I know this because some of the paths in the backtrace below start
with /usr/local and others start with /usr/lib/python2.6/dist-packages.

This will install almost everything you need. It seems grc wasn’t
configured. You might want to find out why as GRC is an indispensable
tool
for a gnuradio user.

good luck
