Hi Mike, yep, whenever you update libraries (which changes their ABI), you'll have to rebuild *all* software that depends on it. In your case, this includes not only GNU Radio, but seemingly also UHD.
Question: Did you make any modifications to either GNU Radio or UHD? Otherwise, I'd just say: uninstall both the GNU Radio and UHD you have now, and install both via DNF – in Fedora 27, you'll get UHD 3.10.1.0 and GNU Radio 3.7.11, both pretty recent. So unless you really need a specific version of UHD, no reason to build from source; unless you need a specific or modified version of GNU Radio, no reason to build that either :) Best regards, Marcus On Tue, 2018-01-30 at 15:45 -0500, Mike Gilmer wrote: > Yes, thanks - I figured out I needed to have been doing that. ;-) > > What a drudgery - I had to make changes to many files to get as far as I've > gotten (now up to 87% finished) and now I'm getting the errors: > > /usr/bin/ld: warning: libboost_date_time.so.1.58.0, needed by > /usr/local/lib64/libuhd.so, not found (try using -rpath or -rpath-link) > /usr/bin/ld: warning: libboost_filesystem.so.1.58.0, needed by > /usr/local/lib64/libuhd.so, not found (try using -rpath or -rpath-link) > /usr/bin/ld: warning: libboost_program_options.so.1.58.0, needed by > /usr/local/lib64/libuhd.so, not found (try using -rpath or -rpath-link) > . > . > . > > Any ideas? > > Thanks. > Mike > > On Tue, Jan 30, 2018 at 11:29 AM, Jeff Long <willco...@gmail.com> wrote: > > Import errors can happen for a variety of reasons, even if the packages are > > still in the right place.
