[Nix-dev] iterating over outputs of derivations

[Luis Torres]

Howdy,

I'd like to generate an attribute that is a string of all my derivation's
buildInputs. I'm currently trying this:

buildInputs = ...

inputPaths = stdenv.lib.concatStringsSep ";" buildInputs;

This does not work if a buildInput has multiple outputs, like boost for
example. The boost derivation outputs paths for ${boost.lib} and
${boost.dev}. The above line would only capture boost's "out" path; how can
I add all outputs of all buildInputs to my attribute?

Thanks,
Luis
