This means there is extra work for you to do one way or the other - if you decide to upload newer versions of your dependencies, you'll have to package them yourself. If you go back and use the existing dependencies (which might be a good idea) then you will have to change your software to use different functions and / or libraries to get the functionality you need.</div><br><blockquote type="cite">I would like to have the app in the repo before the summit :-)<br></blockquote><div><br></div><div>Three weeks left - but definitely doable.</div><br><blockquote type="cite">(I used apt-cache show... and also searched for the python packages through <a href="http://maemo.org/packages/">http://maemo.org/packages/</a> , but don't know how to continue).<font class="Apple-style-span" color="#000000"><font class="Apple-style-span" color="#0000DD"><br></font></font></blockquote><br></div><div>I think the best thing for you and your users (remember they are going to use the existing repos too) is for you to limit the amount of dependencies your software uses. Yes, this limits the functionality you can use and also limits the opportunity to use code already written, but it avoids hard to solve dependency problems. Of course, only you can decide exactly what balance you want to strike, but adapting your software to the existing libraries means you are more likely to have stable, well-tested dependencies.</div><div><br></div><div>Jeremiah</div></body></html>
