you got it! 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. Than

This function in UHD will first look for the environmental variable and then use the UHD installation path to look for the xml files. https://github.com/EttusResearch/uhd/blob/8bb15ee133ea98d6755d392b8493966c785291dd/host/lib/rfnoc/blockdef_xml_impl.cpp#L155 which calls https://github.com/EttusRes

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 c

This necessity for setting UHD_RFNOC_DIR should probably be added to the UHD manual. On Fri, Mar 23, 2018 at 2:15 PM, Derek Kozel via USRP-users < usrp-users@lists.ettus.com> wrote: > Hello Matis, > > UHD uses RFNoC internally at all times since the 3.10.0.0 release. The XML > files are needed fo

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. Regards, Derek On Fri, Mar 23, 2018 at 6:05 PM, Matis Alun via USRP-users < u

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. matis Le 23/03/2018 à 17:35, Marcus D. Leech via USRP-users a écrit : > On 03/23/2018 12:30 PM, Matis
