#20648 new defect

Mutually exclusive depends called recursive depedency

Reported by: openwrt@… Owned by: developers
Priority: normal Milestone:
Component: packages Version: Chaos Calmer 15.05
Keywords: Cc:

Description

using configuration options like:

config X

bool "boolX"
default n
depends on (PACKAGE_P && (!(Y))

config Y

bool "boolY"
default n
depends on (PACKACK_P && (!(X))

results in a warning about there being a recursive dependency
(X depends on Y and Y depends on X)

When in fact the opposite of a recursive dependency is the case (that is X depends on not Y and Y depends on not X).

Both can be false but only one can be true, and this shouldn't
trigger the warning where X needs Y and Y needs X.

This is true of CC and is probably true for trunk too.

Have not yet tested, but the necessary functionality may be possible with only one of the having the not (!) operator (since if Y then X will not be visible, and if X is selected and then Y then X probably will be deselected and disappear).
