If I understood correctly, Vipin in trying to compile his own OOT.
In that case, you can just switch to C++11 independently of GNU Radio AFAIK.
You can do that by putting `set(CMAKE_CXX_STANDARD 11)` into your root
CMakeLists.txt.

Hi Vipin - Easiest way is to just install gnuradio-devel:
{{{
sudo port -f deactivate gnuradio
sudo port install gnuradio-devel
}}}
Assuming that the 2nd command works, then in your OOT when you "make"

Hello list,
I’m posting the following issue vicarious for GitHub user „mustaphos“, who
unfortunately does not make use of the mailing list despite I directly
suggested him to do so. Since I don’t think this is a gr-inspector issue,
I’m posting this publicly for discussion.

Hello Ali,
That "bandwidth" parameter of the UHD Source/Sink block is used to adjust the
'analog bandwidth' of the 'daughterboard'. Most of the daughterboards have a
fixed analog bandwidth, so that parameter will be simply ignored in most cases
('uhd_usrp_probe' will give the detailed info
Dear all,
I have a question related to the parameters Samp Rate (Sps) and
Bandwidth which can be found on the UHD USRP source and sink GNU radio
blocks.
If I want to calculate the bandwidth of a modulated signal (QPSK for
example), the standard equation to use is usually:
B =
gnuradio - $ cmake -DCMAKE_INSTALL_PREFIX= ../ command - Stack Overflow
body,.top-bar{margin-top:1.9em}
I am following the example square_ff at
https://wiki.gnuradio.org/index.php/OutOfTreeModules, but was confused by
the usage of this $cmake command. I didn't specify anything to cmake while
Hello Ali,
The bandwidth parameter will select the Analog RF filters where possible.
For the X310 the daughterboards do not have configurable filters so you
will have to add a lowpass filter to your flowgraph.

Hi,
I don't want my sampling rate to be 25 kHz. My sampling rate is already
195312 Hz which is I think the minimum sampling rate for X310.
What I want is to filter out the frequencies which are at least 25 kHz away
from my center frequency. For example I don't want to see a transmission
which is
Hi,
I was converting the single channel FFT block to dual channel FFT block.
I took the fft_vcc_fftw.cc code and tailored it for dual channel. Also I
edited the corresponding xml file.
But when I try to run it in any application from GRC, it says
self.fft_vxx_0_0 = Template error: #if
A quick reminder, for those interested to meet to discuss the latest
developments related to GNURadio in France and Europe, that the deadline
for submission and registration for the French GNURadio days is approaching
(May 20).
