You must not add a dependency between choice members, because such a dependency would create an invisible entry. In the followint test case, it is impossible to choose 'C'. [Test Case 1] choice prompt "Choose one, but how to choose C?" config A bool "A" config B bool "B" config C bool "C" depends on A endchoice Hence, Kconfig shows the following error message: Kconfig:1:error: recursive dependency detected! Kconfig:1: choice contains symbol C Kconfig:10: symbol C is part of choice A Kconfig:4: symbol A is part of choice For a resolution refer to Documentation/kbuild/kconfig-language.rst subsection "Kconfig recursive dependency limitations" However, Kconfig does not report any error for the following similar code: [Test Case 2] choice prompt "Choose one, but how to choose B?" config A bool "A" config B bool "B" depends on A config C bool "C" endchoice This is because menu_finalize() reparents the menu tree, making 'B' a submenu of 'A'. With reparenting, the menu tree: choice |- A |- B \- C ... will be transformed into the following structure: choice |- A | \- B \- C Consequently, Kconfig considers only 'A' and 'C' as choice members. This behavior is awkward. The second test case should be an error too. Now, let's stop reparenting inside a choice.
