hi all,
I have a simple question (have searched but didn't get any good answer
yet):
what's the best way to enable a config item without interactive
interface? if I know the module name, I can find the CONFIG_ name by
this: then in menuconfig to search SENSORS_APPLESMC to enable it;
$ find -name Makefile |xargs grep -w applesmc
./drivers/hwmon/Makefile:obj-$(CONFIG_SENSORS_APPLESMC) += applesmc.o
but is there a good way to enable it without interactive interface?
the interactive config interfaces (menuconfig/gconfig/xconfig) are good
for one or two configs, but when I want to enable a list of modules,
this solution is not scalable;
I've tried localmodconfig with LSMOD= env variable, but the
localmodconfig doesn't seem to be working in this way, I feel it's
working by an elimination way, to start from a known to be working
config (maybe from a distro or somewhere)
$ LSMOD=~/tmp/modules-merged make localmodconfig
while, I want to start with `make defconfig` and enable a list of config
needed; that to accept a list of CONFIG_* names, or a list of modules
name, does anyone if such a config method exists?
thanks,

You simply need to enable it in your .config file and rebuild.

that simply doesn't always work; for example I started with a minimal defconfig
and want to enable SENSORS_APPLESMC, from nconfig I can search this one
get it depends HWMON && INPUT, if the current .config doesn't have HWMON
and I just write SENSORS_APPLESMC=m there, the following rebuild will deselect
SENSORS_APPLESMC actually;
┌── Search Results ───────────────────────────────────────────────────┐
│ │
│ Symbol: SENSORS_APPLESMC [=m] │

└─────────────────────────────────────────────────────────────────────┘
I am asking a config method that accepts a list of config items (or module names),
let it make sure all depended items also be selected?
thanks,
