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.

Also note the DATE element is only included in the DISTRO_VERSION for
development snapshots.

Since the DATE element is only included in the DISTRO_VERSION for
development, then I'd suggest that our SDK_VERSION logic to be as:
If DISTRO_VERSION contains snapshot
SDK_VERSION = 0.9+snapshot (stripe off the date part)
Else
SDK_VERSION = DISTRO_VERSION (which means the DISTRO is a stablized and
meaningful version, e.g. M3_RC1, etc, or 1.0 relrease, etc.)

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

This way we can easily link the SDK_VERSION to DISTRO_VERSION and avoid the
unnecessary version issue during the development cycle...

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

Liping, could you try to come up a new variable for your purpose?

As Kevin mentioned, can we derive SDK_VERSION from DISTRO_VERSION so only
contains 0.9?

Thanks
Kevin
