This has been failing for years, because upstream hasn't updated it to work with recent Boost releases: checking for boost version... 1_63 configure: error: boost version 1_63 is not supported The last time this built successfully was for F23, and that package supports Boost 1.58.0 I don't know if the F23 package is usable with the newer Boost versions in F24+
dtardon's boost-gdb-printers-6-1.fc26 completed http://koji.fedoraproject.org/koji/buildinfo?buildID=861201
Thanks David! I didn't realise upstream had updated it.
Oh, and didn't realise you are the upstream :-)
