Again on "cannot import name bbn"

Hi list!
I tried to install the 802.11 BBN code following exactly the instruction
in
the https://www.cgran.org/wiki/BBN80211 page but when I run any example
I
got this error:

Traceback (most recent call last):
File “bbn_80211b_rx.py”, line 33, in
from bbn_80211b_pkt import *
File “/home/cmdd/bbn_80211/src/examples/bbn_80211b_pkt.py”, line 31, in

from gnuradio import bbn
ImportError: cannot import name bbn

My machine is an OpenSUSE11 and I installed both current GNURadio
version
and subversion r7596.
Do I forget something?
Thanks a lot
Chiara

Hi Chiara,

I have only tried installing it on Ubuntu. I wrote the instructions on
CGRAN and it worked fine for me.

Are you making sure you get no errors trying to make or make install on
it?

Hi George!
When I run ./bootstrap I get this:

doc/Makefile.am:77: %'-style pattern rules are a GNU make extension doc/Makefile.am:80:%’-style pattern rules are a GNU make extension

I thought it was only a warning but probably it isn’t so…
I searched the way to fix it in the web but I did not find any clear
information (I am quite new to Linux/GNU Radio).
However ./configure seems ok but when I run ‘make’ I get this:

Hi George!

Seems the wrong version of something like automake.

Have you checked that all your used auto-tools are at the same or
higher version as specified in the README file?

Often systems have more than one version of say automake installed, and
you can configure via a distribution-specific tool which one to use or
you can use environment variable to select the right one.

If unsure, send us the output of ‘automake --version’.

This is indeed a warning, and harmless.

bbn_tap.cc: In constructor ‘bbn_tap::bbn_tap(std::string, int)’:
bbn_tap.cc:51: error: ‘memset’ was not declared in this scope
bbn_tap.cc:53: error: ‘strncpy’ was not declared in this scope

Are you using gcc 4.3? It now enforces having the proper #include
directives for certain standard library functions that it would
previously silently ignore. I’d try adding

#include <string.h>

…at the top of bbn_tap.cc to see if this goes away.

I had the same problems and I ended up wasting half hour adding
#include to about 30 odd files. I would suggest that you
change your g++ to an older version. Install g+±4.2 and then do this:

sudo rm /usr/bin/g++
sudo ln -s g+±4.2 /usr/bin/g++

then make.

This is a known problem in gcc-4.3 and 4.4. See here:
http://www.cyrius.com/journal/2007/05/10#gcc-4.3-include
http://www.cyrius.com/journal/gcc/gcc-4.4-include

If need be, I can post my updated source files of BBN (with the added
#includes). Let me know.

First of all, thank you very much for your help.
Now everything seems OK: I am using gcc version 3.4.1 and I only added

#include <string.h>

at the top of bbn_rap.cc and bbn_plcp80211_bb.cc.
Thanks again… now I can start working… :smiley:
