Package: dnsprogs Version: 2.57 Severity: wishlist Tags: patch User: [email protected] Usertags: ld-as-needed
dnsprogs underlinks its public libaries when built with ld --as-needed. With --as-needed objects must be before libraries providing their undefined symbols. Else they will be dropped. This causes problems in reverse dependencies linking to the libraries [0] See the ubuntu buildlog for rdepend muroard failure: https://launchpadlibrarian.net/83077507/buildlog_ubuntu-precise-i386.muroard_0.1.8-1_FAILEDTOBUILD.txt.gz /usr/bin/gcc -Wl,-Bsymbolic-functions -Wl,-z,relro -Wall -Wextra -g -O2 -o muroard muroard.o para.o network.o waveform.o proto.o dsp.o clients.o streams.o memmgr.o cf_au.o cf_riff_wave.o driver.o main.o -ldnet_daemon -ldnet -lao /usr/lib/gcc/i686-linux-gnu/4.6/../../../../lib/libdnet_daemon.so: undefined reference to `crypt' See ldd -r for the missing links: ldd -r ./libdap/libdnet-dap.so undefined symbol: getnodebyname (./libdap/libdnet-dap.so) undefined symbol: dnet_recv (./libdap/libdnet-dap.so) ldd -r libdaemon/libdnet_daemon.so.2.43.1 undefined symbol: dnet_htoa (libdaemon/libdnet_daemon.so.2.43.1) undefined symbol: crypt (libdaemon/libdnet_daemon.so.2.43.1) undefined symbol: getobjectbyname (libdaemon/libdnet_daemon.so.2.43.1) undefined symbol: getnodebyname (libdaemon/libdnet_daemon.so.2.43.1) Attached patch fixes the issue by reordering the commandline correctly.
