Package: libogdi3.2
Version: 3.2.1+ds-3
Severity: minor
File: /usr/lib/libvpf.so.3.2
User: debian...@lists.debian.org
Usertags: undefined-symbol adequate
libvpf.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 other architectures, see the w3m/getbuildlog output below.
I filed this bug at severity minor since everything currently in Debian
that uses libogdi3.2 (GDAL) seems to also use libm.so.

$ man adequate | grep -A6 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.

The build logs contains a like 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.
