Kconfig:278: warning: the 'modules' option is not supported. Let me know if this is a problem for you, as it wouldn't be that hard to implement. Note that modules are supported -- Kconfiglib just assumes the symbol name MODULES, like older versions of the C implementation did when 'option modules' wasn't used.

btw, nuttx can be compiled successfully through the "make menuconfig "and " make", but when I enter the "make menuconfig" command, it runs very very slowly and it takes about several minutes to display menuconfig.
