Thanks for your prompt reply, Michael. I have successfully installed both
gnuradio-master and uhd-master from source. I would like to build an image of
the X310 using the OOT block gain in the example folder. However, the
rfnoc_image_builder.py is giving me an error. I wonder if the syntax I am
providing is correct?
First mkdir and cmake from a build folder in the OOT gain example:
nvd@nvd-VirtualBox:~/rfnoc/src/uhd/host/examples/rfnoc-example/build$ cmake ../
-DUHD_FPGA_DIR=~/rfnoc/src/uhd/fpga/

Also, for using the rfnoc_create_verilog requires a yaml configuration file as
input. Is there an example or documentation somewhere of the format of this
configuration file? Is gain.yml the file that was provided to
rfnoc_create_verilog to produce the OOT in the example folder?

Nope. gr-ettus is, plus or minus, integrated into gr-uhd on GR master. - MLD

Is gr-ettus still required for rfnoc on master branch? I cannot install

When I run gnuradio-companion the rfnoc blocks are missing.

Hi Jeff - The new tool is called "rfnoc_create_verilog" ... it's located in the
UHD repo as "host/utils/rfnoc_blocktool/rfnoc_create_verilog.py". - MLD

I also would like to know the answer to Rob’s question:
Rfnocmodtool is in gr-ettus but if I try to install gr-ettus with the uhd
master branch, I get the following error:

So how does rfnoc work with master branch?
I have also installed UHD-3.15.LTS without PYBOMBS and there were errors that
have been fixed in the master branch but not UHD-3.15.LTS.
There are no current versions of UHD that work with RFNoC to build OOT without
the PYBOMBS method.

Subject: [USRP-users] creating an rfnoc block on master branch
Hi,
How do I create an rfnoc block using master branch? I am familiar with using
rfnoc_mod_tool with UHD 3.15 and earlier. My understanding was that things are
different with master (and uhd 4.0) such that a different tool would be used
and that this new tool would be part of UHD rather than part of a gnuradio
installation. But, I don't see any such tool in my uhd master checkout.
