That's right. I already checked back with the CMake crowd (the
critical lines are automatically created by CMake) and we might find
ourselves in a little bit of a tricky situation here: If a library
libA is merely linked against libB, we of course don't want to know
about the implementation details of libB.
If the headers in libA-dev include something of libA-dev though,
libA-dev should depend on libB-dev. Correct?
If the headers of libB-dev only appear in the sources of libA, i.e.,
libA doesn't provide an interface to libB, libA-dev should *not*
depend on libB-dev. Correct?
Right now, the dependency structure in debian/control looks like
libA:
Depends: ${shlibs:Depends}, ${misc:Depends}
libA-dev:
Depends: libA (= ${binary:Version}), ${shlibs:Depends},
${misc:Depends}, libB-dev
Would you consider this sane? Will whatever magic acts in
${shlibs:Depends}, ${misc:Depends} be able to identify libB as a
dependency of libA?
Cheers,
Nico
