Because of choice-in-a-choice constructs, it can happen that not all symbols are assigned a value during randconfig, leading in rare cases to this situation: ---8<--- choice-in-choice.in choice bool "A/B/C" config A bool "A" config B bool "B" if B choice bool "E/F" config E bool "E" config F bool "F" endchoice endif # B config C bool "C" endchoice ---8<--- $ ./scripts/kconfig/conf --randconfig choice-in-choice.in [--SNIP--] $ ./scripts/kconfig/conf --silentoldconfig choice-in-choice.in </dev/null [--SNIP--] A/B/C 1. A (A) > 2. B (B) 3. C (C) choice[1-3]: 2 E/F > 1. E (E) (NEW) 2. F (F) (NEW) choice[1-2]: aborted! Console input/output is redirected. Run 'make oldconfig' to update configuration. Fix this by looping in randconfig for as long as some symbol gets assigned a value. Note: this was spotted with the USB EHCI Debug Device Gadget (USB_G_DBGP), which uses this choice-in-a-choice construct, and exhibits this problem. The example above is just a stripped-down minimalist test-case. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr>
