This was very interesting. A few questions:
is "Samples per block" = samples per buffer ?
How is the old:
dev_addr["recv_buff_size"]=2; uhd::usrp::multi_usrp::make(dev_addr);
related to sbp and spp ?

Thanks for everyone's work on this - greatly appreciate the rapid turnaround.

Thanks to all who worked to fix the Ubuntu 32 bit build problem. I have
been building it on my systems and while it is not complete there are no
indications that it isn't working correctly.

Thanks to Marcus and Josh for helping to identify the problem with the
32-bit OSes. I just pushed a fix for this. It was a trivial patch but not
at all obvious. Apparently, it has to do with how SWIG and Python interact
with templates.
I also pushed a handful of other minor fixes, including the

Hi Ed,
I've been doing the same recently with gnuradio-3.4 on ubuntu 12.04 x64, So
I'm guessing it's pretty similar.
Anyway, copying and pasting some notes I made which should hopefully help
you, there were a few little horrors in there!
NB The boost version is probably not that important so lon

Admittedly, the time between the pre-announcement and this email is

So, the Google Summer of Code (GSoC) has been announced.
