Hi Richard,
I’ve already unsuccessfully tried all these combinations with both “if” and
oe.utils.conditional.
$ MACHINE=qemuarm bitbake rust-native -e |grep CRATE_CC_NO_DEFAULTS
# $CRATE_CC_NO_DEFAULTS [3 operations]
# [export] "${@1 if d.getVar('CRATE_CC_NO_DEFAULTS') == 'true' else 0}"
export CRATE_CC_NO_DEFAULTS=""
# $CRATE_CC_NO_DEFAULTS:class-native
CRATE_CC_NO_DEFAULTS:class-native=""
$ MACHINE=qemuarm bitbake rust-native -e |grep CRATE_CC_NO_DEFAULTS
# $CRATE_CC_NO_DEFAULTS [3 operations]
# [export] "${@'1' if d.getVar('CRATE_CC_NO_DEFAULTS') == 'true' else ''}"
export CRATE_CC_NO_DEFAULTS=""
# $CRATE_CC_NO_DEFAULTS:class-native
CRATE_CC_NO_DEFAULTS:class-native=""
Looking at this “0” should work
https://git.yoctoproject.org/poky/tree/meta/classes-recipe/go.bbclass#n30
But, even if I add
CRATE_CC_NO_DEFAULTS[export] = "0"
for testing, I still see:
$ MACHINE=qemuarm bitbake rust-native -e |grep CRATE_CC_NO_DEFAULTS
# $CRATE_CC_NO_DEFAULTS [3 operations]
export CRATE_CC_NO_DEFAULTS=""
# $CRATE_CC_NO_DEFAULTS:class-native
CRATE_CC_NO_DEFAULTS:class-native=""
Cheers,
Anton

I think it might need to be 0 or "" instead of '0'. It would be nice if
we could make False work too but I worry that might not.
Cheers,
Richard
