#201550 — Package shared library with application

[Multipart message — attachments visible in raw view] — view raw

Hi All,


I'm trying to package my application together with a shared library that I have written but run now into following error:


dpkg-shlibdeps: error: no dependency information found for /usr/lib/x86_64-linux-gnu/libkImageAnnotator.so.0.0.1 (used by debian/ksnip/bin/ksnip)
Hint: check if the library actually comes from a package.


After searching for a solution, I saw that some folks suggest, as a workaround, to add following to the rules:


override_dh_shlibdeps:

     dh_shlibdeps --dpkg-shlibdeps-params=--ignore-missing-info


Is that a correct approach or just a hack that could cause later on problems?


Thanks in advance!


Best regards,
Damir

If you're only using the package internally, it's fine.

If you're planning on offering the application to Debian or to
the public, you should make a separate package for
libkImageAnnotator or include it in this one formally.

It is difficult to help without the complete picture.  Can you please
provide the complete build output from when you built the package and
the complete console output from the package installation and the fail
launch attempt?

It looks like your build does not actually create/install a library
called libkImageAnnotator.so.0.0.1.  That would be why it cannot be
found by the application binary.  Is the source package available online
somewhere I can take a look?

Here is the part from your pastebin:

Install the project...

It appears that your package build is doing something different than you
think it is, perhaps depending on the build environment.

I will try to take a look at it a bit later.

Do you have it in the install file and also I am not sure about the
CamelCase
Does it install correctly after compilation?
