Hi, Jessica & Josh

When we are trying to run installer script on lianhao's x86_64
machine, we found if the images are build in two days, according to
current version naming convention, some of the packages will be
installed to /opt/poky/0.9+snapshot-20101210, some will be to
/opt/poky/0.9+snapshot-20101210.
It will cause problem since we need to know the exact version number
before installing and searching some files (environment script file,
etc). And the same releases of packages belong to different version
(just the build date is not in the same day) seems very strange and
hard to handle for us?
I think Josh has laid down the base for multiple version SDK support.
The only problem is:

SDKPATH = "/opt/${DISTRO}/${DISTRO_VERSION}"

which obviously is not what we want. We need a similar variable like
SDK_VERSION, which is incremented only when SDK team thinks there's a
need for a new version release or
else it keeps same in the life cycle of current version.
I disagree, I think it's definitely useful to know which distribution
version your SDK is built against. In fact as the SDK components are
generated from the distro metadata introducing an extra variable seems a
little superfluous and just increases the number of things which need to
be changed for a release.
Yes, SDK is generated from the distro metadata, which however doesn't prevent SDK
as a standalone component to have its own version variable. We can have:

SDK_VERSION = ${DISTRO_VERSION}

or,

SDK_VERSION = ${DISTRO_VERSION}${SDK_REVISION}

or,

SDK_VERSION = ...

I'm just a little bit worried to deduce SDK version from another variable (SDKPATH)
implicitly.

I agree that to have distribution version included will be informative, e.g in Android:
"SDK platform Andriod 2.3, API 9, revision 1"


Also note the DATE element is only included in the DISTRO_VERSION for
development snapshots.
Good to know this info.

Thanks
Kevin
