For future reference, 'git fetch' simply pulls the list of changesets.
In order to apply them to your current branch, you need to use 'git
merge'.

I never received this error in 32-bit ubuntu.
I did a ./bootstrap, but receive this error:
configure.ac:47: warning: AC_PROG_LIBTOOL is m4_require'd but not m4_defun'd
config/gr_scripting.m4:22: GR_SCRIPTING is expanded from...
configure.ac:47: the top level
configure.ac:47: warning: AC_PROG_LIBT
So what does this update actually do? Does it add UDP onto the network
stack? What about VRT? I know VRT and UDP are being implemented
independently, but around the same time. How does this update fit in with
adopting those two protocols?
Thanks

Hello,
where can I find the USRP2 BOM? I only found the PDF files for the
schematics, and the SVN repository does not have USRP2 files.
Thanks!

Hi,
Let me clear my issue. My source file includes number of complex
numbers which can be read by using matlab function "read_complex_binary.m".
I observed that the data are same as when they passing through
"gr_file_source::work" ->???-> "gr_ofdm_frame_sink.cc" however, I observed
that in "gr
So what is the cause of the problem?

Hi, everyone,
I just got two set of USRP2 and want to test it using the bbn 802_11b
usrp2_version. I use the example scripts: bbn_80211b_rx.py and
bbn_80211b_tx.py.
I use the default setting: on one machine: ./bbn_80211b_rx.py and on another
machine: ./bbn_80211b_tx.py
The tx script work correct
The package libtool was missing.

I think that is a buffer overrun. In otherwords, your computer cannot
process the data fast enough.

Yes. This might help.
"At a decimation rate of 4 you are generating 25 MS/s. If those samples are
