Package: tcl-expect Version: 5.45.4-1 Severity: minor File: /usr/lib/x86_64-linux-gnu/libexpect.so.5.45.4 User: debian...@lists.debian.org Usertags: undefined-symbol adequate
libexpect.so needs to link with Tcl, 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 other architectures, see the w3m and build log output below. I filed this bug at severity minor since it looks like the code using libexpect.so (expect, skycat) also already uses Tcl libs. This bug report brought to you by adequate: http://bonedaddy.net/pabs3/log/2013/02/23/inadequate-software/ $ adequate tcl-expect tcl-expect:amd64: undefined-symbol /usr/lib/x86_64-linux-gnu/libexpect.so.5.45.4 => Tcl_ErrnoMsg tcl-expect:amd64: undefined-symbol /usr/lib/x86_64-linux-gnu/libexpect.so.5.45.4 => Tcl_Free tcl-expect:amd64: undefined-symbol /usr/lib/x86_64-linux-gnu/libexpect.so.5.45.4 => Tcl_Alloc $ 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.
