Package: libmpx2
Version: 7.2.0-19
Severity: minor
File: /usr/lib/x86_64-linux-gnu/libmpxwrappers.so.2.0.1
User: [email protected]
Usertags: undefined-symbol adequate
libmpxwrappers.so needs to link with -lmpx, 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 i386, see the w3m/getbuildlog output below.
I filed this bug at severity minor since I'm guessing that any code
using libmpxwrappers.so also already uses libmpx.so, or that there is
no code using libmpxwrappers.so.
In addition, the gcc-7 build logs indicate underlinking in these other
libraries: libgphobos.so libgo.so libhsail-rt.so liblsan.so
This bug report brought to you by adequate:

$ adequate libmpx2
libmpx2:amd64: undefined-symbol
/usr/lib/x86_64-linux-gnu/libmpxwrappers.so.2.0.1 => get_bd
$ 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.

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.
