wpa_supplicant tells "No Drivers enabled"

I have compiled wpa_supplicant code downloaded from http://hostap.epitest.fi/wpa_supplicant/ version is 0.7.3. I am getting No Drivers installed while trying to run the built wpa_supplicant. Am i missing anything in its compilation? Has anyone faced this error? Is there any setting to enable drivers also wh开发者_运维知识库ile compiling wpa_supplicant and wpa_cli?

Does your kernel automatically load the correct module for your wireless card? If not, modprobe the correct module, and try again.

Also, the wpa_supplicant(8) page's AVAILABLE DRIVERS section says that only a handful of cards are supported (disappointing, but at least you could look through the list before buying a card), and that support for the drivers may or may not be compiled in. So make sure your card's driver is on the list, and make sure you've compiled wpa_supplicant(8) with the correct driver.

You have to choose a driver to use by enabling it in .config file of wpa_supplicant before build. They will be in the form CONFIG_DRIVER_<name>.

CONFIG_DRIVER_WEXT and CONFIG_DRIVER_NL80211 are generic that suits many hardware.
