Hello Andrew, I did a fresh install of the latest rfnoc-devel (using pybombs prefix init > ~/rfnoc -R rfnoc -a rfnoc) and RFNoC blocks do not work (such as FIR and Rx > Radio, possibly related to USRP-users mailer subject: Core dump with > UHD_3.11, X310, and LFTX). So I am trying to checkout and build rfnoc-devel > to a known stable commit: aec2fe9. I ran git checkout aec2fe9 in > rfnoc/src/uhd, rfnoc/src/gnuradio, and rfnoc/src/gr-ettus. Then from > uhd/host/build I ran cmake ../ but got this error: > > > > CMake Error: The source directory "/home/switchlanez/rfnoc/src/uhd/host" > does not appear to contain CMakeLists.txt >
Please correct me if I'm wrong, but did you run "git checkout aec2fe9" in *all* those repositories? that Git hash might be correct for only one of them, and the corresponding according commit in the other repositories remains unknown. Where did you take that hash from? If what I understood is what you did, that might be causing you problems. You need to identify which commits for each of the repositories is according to an "stable" version, and checkout accordinglu and respectively. > So I downloaded that file from GitHub with the closest date on or before > aec2fe9 was released and tried cmake ../ again.

Reverting to older commits is something that is commonly done, yes. From what I understood you run to a same hash in all of the involved repos.

If you change the branch, you wouldn't be able to use all the RFNoC features needed for development. Cheers, - Nicolas
