Launchpad itself

How to tell a recipe to use a library on another PPA?

Asked by Cecilio Salmeron

I have a library called lomse (https://launchpad.net/~lomse/+archive/ppa) which builds at launchpad using a recipe.

And I have an application, lenmus (https://launchpad.net/lenmus) that needs that library. I would like to use launchpad build system for creating packages for lenmus but my problem is that I don't know how to specify to the recipe where it can find the liblomse.deb package. It is in my other project PPA but I don't know how I can add this to lenmus and how.

A second related issue is that for testing lenmus in my machine, before requesting launchpad to build the recipe, I'm using pbuilder (following the guidelines in documents Packaging/SourceBuilds/GettingStarted ). Again, I don't kown how to tell pbuilder to use the liblomse.deb package.

Thanks for any help!

Hi, if you look at https://launchpad.net/~lomse/+archive/ppa/+edit-dependencies this will help.

Thank you very much Laura.

It was really simple to add my other pakage to the recipe. Thanks for pointing me to the right place.

The second issue I have is about testing my recipe locally before sending it to Launchpad. I understand that I have to set up pbuilder so that it can install my other package in the environment it prepares for building. Again, I don't know how to do it. Could you please explain me that or pointing me to a simple document for dummies where it is explained, step by step?

Thank you very much.

Laura,
Thank you very much for the link. I hope now I can finish with this issue of packaging the program.

Best regards,
