Hi Ranga,
that's what pointers are for, after all. Just do it! Thanks to the
make()-magic you basically always have a smart shared pointer instead of
an block object (unless you really try to break the system ;) ).
Just a quick note though: MAC is usually timing-relevant. Timed commands

Hi bzs,
really short:
pfb = polyphase filter bank = what it is
arb = arbitrary
resampler = what it does
ccf = complex in, complex out, float taps

Hi,
It seems to me that gqrx cries for libgnuradio-runtime-3.7.2git.so.0.0.0,
but latest GR brings 3.7.3 into the system. Did I miss smth., or are the
projects just not yet "in sync"?

Well, did you rebuild everything after updating GR ?

Ah, I forgot gr-iqbal! All the other stuff I updated and rebuilt, just not
this one. Now it looks better, it only complains about the missing HW

Marcus,
Thanks for your reply. What will the shared pointer be called. I see stuff
like this in the code:
GR_SWIG_BLOCK_MAGIC2(uhd, usrp_source)
GR_SWIG_BLOCK_MAGIC2(uhd, usrp_sink)
GR_SWIG_BLOCK_MAGIC2(uhd, amsg_source)
Presumably, that generates a structure that is registered as a global
poin
In GR 3.7, the shared pointer is usually blockname::sptr;
I can't really point you to a very good example, but when you call
top_block.connect(src, sink) in C++, you're giving it spointers :)
As I said, whenever you make a block, you actually get a shared pointer
to that instance, and not the o

Looking around I don't see where the pointer to the block is made globally

Why does the MAC block need to "reach around" way down into the depths of the PHY layer?

No where.
There could be several UHD source/sink blocks, so nothing will be made
globally visible by GR.

I am working on a dynamic spectrum mac where the MAC will reach out to a TV
White space DB (and also potentially do spectrum sensing) and adjust the
centre frequency of the USRP periodically.
Thanks for your help!

Hi Ranga,
either you're seriously astray or I don't understand what you want.
This is C++ running on an operating system with segmentation. There are
*no* globally visibly objects, there is only calls to the operating

Based on what you and others have replied, I think my "most elegant" plan
of attack would be to toss the generated puthon glue code (which I
generated using grc-companion BTW) and do everything in C++ so I dont have
to worry about the language interface at all.

Dear All,
I will ask you very old and classical question:
'RuntimeError: No USRPs found on interface eth0'
I have USRP N200
I run:
$ sudo ifconfig eth0 192.168.10.1
$ uhd_find_devices
linux; GNU C++ version 4.4.1; Boost_103800; UHD_003.005.004-140-gfb32ed16
The solution is the USRP2 interface is no longer supported, and software
which uses it must be ported to UHD. The find_usrps tool is no longer
usable with modern Ettus hardware.

Try:
uhd_usrp_probe --args "addr=192.168.10.2"
Also, be certain that Network Manager isn't resetting the interface back to DHCP (automatic IP address selection). If Network Manager "owns"
the interface, *and* the interface isn't configured for static-IP according ot Network Manager, it'll keep
Gah!
I missed the second-half where nesazeri was using find_usrps.
Indeed, if you have software that uses the "classic" (pre-UHD) interface, that interface has been obsolete for several years and is no longer
supported. The N2XX in particular, *does not* support the "classic" interface.

MacPorts, which works for me on 10.8 and 10.9, to get full GNU Radio with GRC

Hi,
build-gnuradio does not yet support debians latest stable version 7.2,
although it builds nicely.
I attached a patch, it just adds 7.2 to the debian_version switch in line 588.
