Re: [OE-core] [RFC] bbclass for automatic generation of binary recipes
Is it similar to meta/classes/package.bbclass ?

Hi,
Background:
If you use OE to build software which includes e.g. a closed source
library, but still want to others to be able to build software based
on that library in a OE environment you would have to create recipes
that contains a binary version of your library + headers manually.
This would have to be done manually for each package, and as the
development of the library continues the binary recipes will have to
be manually updated to keep in sync.
Idea:
Create a new bbclass that handles this automatically as much as
possible. The basic idea is to:
- Create a tarball of ${WORKDIR}/image/ alternatively
${WORKDIR}/packages-split/
- By parsing the "source recipe", create a "binary recipe" that uses
that tarball
The binary recipe should work as a drop in replacement of the source
recipe. This means that the other recipes depending on the closed
source software shouldn't need to be adapted to work with one or the
other.
I'd like feedback on whether you think the idea is feasible, and if
you think it could be useful for others. And anything else you think
of.

I would say it's in addition to package.bbclass.
The idea is that the developers of the closed source software uses OE
to build their software from source, and in this build process the
files needed for a binary distribution in OE is automatically
generated. These generated files can be distributed to others that
wish to use that closed source software in OE. So it would use some of
the output from package.bbclass, like the package split, but then
generate some extra files.

Oh, hadn't seen that one. That could definitely be useful, the only
thing left to do is to try to automate the generation of the recipe
that uses the binary package.

How about the scripts/create-recipe ? It works fine with the tarball, but
not very well with .rpm/.deb/ipk.

What I have in mind is that the recipes will be created automatically
when building a source recipe that inherits a certain class. The
recipe and tarball would then be placed in a layer structure together
with other recipes that includes that class. Fields like RDEPENDS,
LICENSE; PR etc should be carried over from the source recipe.
Maybe it should be done in a way similar to populate_sdk, so if I
bitbake an image with e.g. -c populate_binary_layer it would create a
meta-layer with binary recipes for all packages inheriting that class.
