description
The build logs contains a line like
dpkg-shlibdeps: warning: symbol NAME used by BINARY found in none of the libraries.
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. - A plugin not linked with a library needed.
dpkg-shlibdeps should ignore plugins and give a different warning for files in non-library directories, so if it really is a plugin, you most likely installed it in a standard library directory by mistake. - dpkg-shlibdeps is not able to find the libraries needed.
(This also means it misses information needed to check dependencies, better do something against this). - a special symbol dpkg-shlibs had not yet in its blacklist.
Currently known is __aeabi_unwind_cpp_pr1@GCC_3.5, which can be ignored on armel and armhf.
