yes, its seems that we loose several dBs but which can be widely compensated by
the
extremely large TwinRx gain range.

I had a previous installation of the UHD library (needed by gnuradio - which I
don't use
to drive ettus hardware).
After a sudo make install of my compiled version, all is ok. But it is a little
bit
confusing that a fresh compiled
version don't work without a make install step.

Does anyone have examples of how to generate waveform IQ files in matlab or

This function in UHD will first look for the environmental variable and
then use the UHD installation path to look for the xml files.

Hi Derek,
Yesterday, I did a "git pull" and "make" of the "maint" HEAD. This was on
a computer that had not been used in several months. The previous version
was definitely 3.10, but I don't know how old. Anyway, following the
build, I could run the examples without getting any error message.
Hi Rob,
The default path for UHD_RFNOC_DIR is configured automatically at build
time. The requirement has not changed since UHD 3.10. What version of UHD
were you building when you encountered the problem. It is not impossible
that this is a bug, though I do not believe that there have been any

Hi Michael,
I just wanted to update you all on this problem. I spoke to Yang that posted
the problem in here
http://lists.ettus.com/pipermail/usrp-users_lists.ettus.com/2017-March/023924.html.
Her issue was that her USRP image was not the same as her version of uhd. I

This necessity for setting UHD_RFNOC_DIR should probably be added to the
UHD manual.

Hello Matis,
UHD uses RFNoC internally at all times since the 3.10.0.0 release. The XML
files are needed for standard operation. It does not expose the full API or
set of features unless the rfnoc-devel branch is used.

Derek

yes, I missed the make install because I thought that it was optionnal.
Tell me if I wrong: RFnoc is not used since we use multi_usrp wright ?
in this case, xml files are also needed ?
Thanks.

Could you do an ls -l on that directory and share it with us?
