Yes, this is what I saw as well...

I had to add two lines to the populate_sdk_ext.bbclass to properly get it to pick up my env script.
I set :

	OE_INIT_ENV_SCRIPT = "setup-build-env"
	CORE_BASE_Files = " \
	     Scripts \
	     LICENSE \
	     .templateconf \
	"
This allowed me to build the "minimale SDK EXT.

	SDK_EXT_TYPE = "minimal"
	SDK_LOCAL_CONF_WHITELIST = "SSTATE_MIRRORS"

Was hoping I would be able to configure the variables rather than modify the script...
Do not want to introduce future support ussues if possible.

Thanks,
Steve

Looking at the code in populate_sdk_ext.bbclass:copy_buildsystem(),
it looks in each layer for the script specified in OE_INIT_ENV_SCRIPT.

From your description its impossible to know whether meta-limws or meta-bae is seen as individual layers and whether they're copied individually into layers/ in the eSDK or not.

I'd guess that " meta-limws/setup-build-env" or "meta-bae/meta- limws/setup-build-env" should work as the value for OE_INIT_ENV_SCRIPT.

If poky is being used and is unaltered, COREBASE and COREBASE_FILES should work unaltered.

Cheers,

Richard
