Lintian tag: weak-library-dev-dependency

Type: error

Description (from lintian-explain-tags)

This package seems to contain the development files for a shared library,
but the requirement for that shared library to be installed does not
include the same version.

A -dev package should normally use (= ${binary:Version}) for the
prerequisite on the shared library. That will ensure that programs compile
and link properly. The symbolic links for the dynamic linker will also
point to the correct places.

To be sure, there are some circumstances when a weak prerequisite is
warranted, for example to prevent the breaking of binNMUs with
architecture-independent -dev packages. Then something like (>=
${source:Upstream-Version}), (<< ${source:Upstream-Version}+1~) may be the
right approach, or possibly ${source:Version} instead. The goal there is
to ensure that a new upstream version of the library does not satisfy the
prerequisite, since any minor version change might break the *.so links.

Please refer to Dependencies between the packages of the same library
(Section 8.5) in the Debian Policy Manual for details.
