Hi,
>So it is explainable that symbol loading works between >fewly different package versions. >I would still like to know how i managed to break it. >Just to be able to avoid this in future. as said before, the debug package should depend on binary:Version binary package. e.g. Package: foo Architecture: any Description: foo package this is the foo binary package! Package: foo-dbg Section: debug Architecture: any Depends: foo (= ${binary:Version}), ${misc:Depends}, ${shlibs:Depends} Description: Debug symbols for Foo This package contains debug symbols for the foo package. cheers, G.
