this is the configuraton file we are using for toaster

we are using the same logic that oe-setup-builddir uses

(based on TEMPLATECONF and .templateconf) to determine

which toasterconf.json to use.

note: There are a number of relative path assumptions

in the local layers that currently make using an arbitrary

toasterconf.json difficult.

. $OEROOT/.templateconf if [ -n "$TEMPLATECONF" ]; then if [ ! -d "$TEMPLATECONF" ]; then # Allow TEMPLATECONF=meta-xyz/conf as a shortcut if [ -d "$OEROOT/$TEMPLATECONF" ]; then TEMPLATECONF="$OEROOT/$TEMPLATECONF" fi if [ ! -d "$TEMPLATECONF" ]; then echo >&2 "Error: '$TEMPLATECONF' must be a directory containing toasterconf.json" return 1 fi fi fi

this defines the dir toaster will use for

1) clones of layers (in _toaster_clones )

2) the build dir (in build)

3) the sqlite db if that is being used.

4) pid's we need to clean up on exit/shutdown

note: for future. in order to make this an arbitrary directory, we need to

make sure that the toaster.sqlite file doesn't default to pwd like it currently does.
