Package: libhavege1 Version: 1.9.4-2 Severity: minor File: /usr/lib/x86_64-linux-gnu/libhavege.so.1.1.0 User: [email protected] Usertags: undefined-symbol adequate
libhavege.so depends on the error_exit symbol but that is only present in the daemon. It seems like the error_exit symbol needs to be renamed to havege_error_exit to be less generic and then moved from the daemon to the library. 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 there are no packages outside of src:haveged that depend on libhavege1 so this issue doesn't affect anything in Debian yet. While investigating this issue I also noticed some very generically named symbols in libhavege.so that really need to be renamed. This bug report brought to you by adequate: https://bonedaddy.net/pabs3/log/2013/02/23/inadequate-software/ $ lib=/usr/lib/x86_64-linux-gnu/libhavege.so.1.1.0 $ link=/usr/sbin/haveged $ pkg="$(dpkg-query --search "$lib" | sed s/:.*//)" $ src="$(grep-aptavail --no-field-names --show-field Source:Package --field Package --exact-match --pattern "$pkg")" $ first="$(printf '%s' "$src" | head --bytes 1)" $ adequate "$pkg" libhavege1:amd64: undefined-symbol /usr/lib/x86_64-linux-gnu/libhavege.so.1.1.0 => error_exit $ man adequate | grep -A4 undefined-symbol undefined-symbol The symbol has not been found in the libraries linked with the binary. 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.
