slight different confirurations for a package

slight different confirurations for a package

[C Michael Sundius]

I'd like to be able to build several different configurations of the same
package and I'm wondering if the community might have some good input on the
best way to organize this. My project has several images that are built for
various products and customers and hardware. Generally all of the software
is the same save a few key packages. (really even the kernel is constant
across all platforms). and right now I have a different disto.conf file that
corresponds to an image recipe for each platform.

I want to be able to build all of the platforms together within the same out
dir. (so I don't have to rebuild the bulk of the software wasting disk space
and time).

I've thought about defining separate recipes:
     (foo-config1.bb, foo-config2.bb)
or simply using a variable to define ${PN} from within the recipe:

    PN = ${DISTRO_CONFIG}

 I suppose these could work, but I'm wondering if I can create a whole new
directory under work and staging like when I set PACKAGE_ARCH =
${MACHINE_ARCH} for the kernel and drivers.

as I said, right now I have a separate distro/*.conf file for each image
(and thus configuration) I build, really the difference between these is the
configuration of just a few packages all other software is built w/ the same
recipe and configs. Is there a way anyone can think of to consolidate these
so I can build everything without
changing the local.conf (DISTRO variable).

I realize this is a nebulous question, but if anyone has an experience
similar where they have had to organize various builds and found a clean or
better way to build them all for both development and production or you have
some opinions about how you made your decisions to do things one way or
another , I'd love to hear your comments.

Thank you
Mike

It seems like you are misunderstanding how to use DISTRO. Basically, set 
the common stuff in DISTRO and creat an image.bb file for each image you 
need.

In short, if you are creating a new distro/*.conf you are most likely 
making a mistake :)

Quick and dirty: If you use the same distro, but have separate recipes 
(foo-config1.bb and foo-config2.bb), you can place them under separate 
tasks/images (image1.bb and image2.bb) and build both images. All the 
packages, except foo-* and image1/2 will be shared and built only once, so no 
wasting of disk space and time.
