Hi people, I've fixed up the spec file for inclusion into Fedora, see: https://bugzilla.redhat.com/show_bug.cgi?id=447847 Next, it seems the configure file cannot deal with an ldns that has its header installed in /usr/include/ldns, with its library in /usr/lib{64}/ with configure --with-ldns or --with-ldns=/usr # Check whether --with-ldns was given. if test "${with_ldns+set}" = set; then withval=$with_ldns; specialldnsdir="$withval" CPPFLAGS="$CPPFLAGS -I$withval/include" LDFLAGS="$LDFLAGS -L$withval -L$withval/lib -lldns" ldnsdir="$withval" fi Since this is the location on Fedora, unbound will mistakenly use the build-in ldns (breaking fedora guidelines of staticly linking to an available shared library) Warnings found: Build util/configlexer.c <stdout>:2466: warning: 'ub_c_unput' defined but not used <stdout>:2509: warning: 'input' defined but not used util/data/msgencode.c: In function 'compress_any_dname': util/data/msgencode.c:333: warning: 'insertpt' may be used uninitialized in this function Cheers, Paul
