Package: libspnav0 Version: 1.0-1 Severity: minor File: /usr/lib/libspnav.so.0.3 User: debian...@lists.debian.org Usertags: undefined-symbol adequate
libspnav.so needs to link with -lm, see the output of adequate, symtree and objdump below. I detected this on amd64 but the Debian build log scanner also detected dpkg-buildpackage complaining about it on most architectures, see the w3m/getbuildlog output below. I filed this bug at severity minor since I'm not sure if there are any programs using the libspnav.so lib and if they already use the libm.so symbols and link with the -lm flag or not.

Either the binary either needs to be linked with an additional shared library, or the dependency on the shared library package that provides this symbol is too weak.

Possible reasons: • A library not linked with a library needed. While this can sometimes make sense in order to allow the using binary to decide which of multiple available implementations to use, it means that dependency information might be incorrect, optimisations like prelinking might fail and stuff like that. $ chronic getbuildlog "$src" last $ grep 'dpkg-shlibdeps: warning: symbol .* used by .* found in none of the libraries' ./*.log
