Hi all,
I have found weird feature of Kconfig.
If I misused something, please let me know - I found at least one place
where the same error occurs.
Let's consider the following Kconfig (you can put it anywhere in the source tree):
<-------------- copy ----------------->
menu "Testmenu"
choice
prompt "Problem to solve"
optional
default n
help
Solve one of great world problems
config SOLVE_HUNGER
bool "Hunger"
config SOLVE_WARS
bool "Wars"
config CURE_CANCER
bool "Cancer"
endchoice
config TREES
default n
bool "Plant trees in garden"
endmenu
config BLAH
default n
bool "Totally unrelated option"
<------------- paste ------------------->
Now, select HUNGER important problem to solve; Warning - select it with space, _not_ enter + selection from list;
Then select either TREES or BLAH.
Weird thing is - SOLVE_HUNGER is unselected.
It doesn't happen when you select (anything) by entering selection menu (i.e. enter).
Even if you deselect option and then select it with space.
It happens both in menuconfig and nconfig.
It happens both in recent U-Boot b57843e6 and Linux kernel ece62678.
Unfortunately my knowledge of Kconfig is very limited so your help would be appreciated.
Best Regards,
Mateusz
