Michael, You hit a bullseye! It took a bit to finally find the culprits while trying to back out packages that were a dependency for something else. I finally did the following to find what I needed to get rid of:
$ dpkg -l | grep -i uhd ii libuhd-dev:amd64 3.10.3.0-2 amd64 universal hardware driver for Ettus Research products - headers ii libuhd003.010.003:amd64 3.10.3.0-2 amd64 universal hardware driver for Ettus Research products - library ii uhd-host 3.10.3.0-2 amd64 universal hardware driver for Ettus Research products - host apps I removed/purged them and rebuilt from the start, and everything built without the error. Thanks again, Jeff ________________________________ From: Michael Dickens <michael.dick...@ettus.com> Sent: Wednesday, April 1, 2020 9:49 AM To: Jeff S <e070...@hotmail.com> Cc: usrp-users@lists.ettus.com <usrp-users@lists.ettus.com> Subject: Re: [USRP-users] Setting Up E310 Environment - Build Error Hi Jeff - I'm pretty sure the error means you have a prior version of GNU Radio installed into a standard system search prefix (e.g., /usr/local ). If you disable / remove / deactivate that install, then redo-the whole GR build from the start, the error should be fixed. Hopefully! - MLD On Wed, Apr 1, 2020 at 10:26 AM Jeff S via USRP-users <usrp-users@lists.ettus.com<mailto:usrp-users@lists.ettus.com>> wrote: I am trying to combine the install using a custom prefix (https://kb.ettus.com/Building_and_Installing_UHD_and_GNU_Radio_to_a_Custom_Prefix) and while following S/W Dev on E3xx (https://kb.ettus.com/Software_Development_on_the_E3xx_USRP_-_Building_RFNoC_UHD_/_GNU_Radio_/_gr-ettus_from_Source).

I have seen where this was a problem in the past, and some people updated the file that had showed the problem. Others redid their build of UHD with a newer version. Those issues were about two years old, and it seems that it still shows up in some situations. Is it due to my trying to combine two Application Notes? Is the recomendation to update uhd_swigPYTHON_wrap.cxx still one solution?
