内核需要选中Bus support -> PCI support，否则编译会报错：

compat-wireless-2012-02-22/drivers/net/wireless/ath/ath9k/pci.c:371: error: redefinition of 'ath_pci_exit'
 

另外

Networking support  ->Wireless -> cfg80211 - wireless configuration API
Networking support ->Wireless ->Generic IEEE 802.11 Networking Stack (mac80211)

需要设置为 ，config.mk会检测kernel的.config中的CONFIG_CFG80211和CONFIG_MAC80211

但是执行./scripts/gen-compat-autoconf.sh时报错：

 error: static declaration of 'usb_buffer_alloc' follows non-static declaration

看起来似乎是代码的定义和kernel的头文件冲突，注释掉compat-wireless-2.6.34.1\include\linux\compat-2.6.35.h:

#define usb_alloc_coherent(dev, size, mem_flags, dma) usb_buffer_alloc(dev, size, mem_flags, dma)
#define usb_free_coherent(dev, size, addr, dma) usb_buffer_free(dev, size, addr, dma)

整个代码都没有调用这两个。

error: invalid application of 'sizeof' to incomplete type 'struct led_trigger'

选中Networking support  ---> Wireless  ---> Enable LED triggers

但是这样编译的话，最后还是有很多ko会报找不到kernel的函数：

多次尝试配置kernel虽然可以减少出错个数，但是任然不能完全解决，看来只有使用driver-select脚本选择需要的wifi驱动，然后编译。

makefile参照网上的patch，以下一段有改动：

obj-$(CONFIG_COMPAT_NET_USB_MODULES) += drivers/net/usb/

obj-$(CONFIG_COMPAT_NETWORK_MODULES) += drivers/net/ethernet/atheros/
obj-$(CONFIG_COMPAT_NETWORK_MODULES) += drivers/net/ethernet/broadcom/

obj-$(CONFIG_COMPAT_VAR_MODULES) += drivers/ssb/
obj-$(CONFIG_COMPAT_VAR_MODULES) += drivers/bcma/
obj-$(CONFIG_COMPAT_VAR_MODULES) += drivers/misc/eeprom/

ifeq ($(CONFIG_STAGING_EXCLUDE_BUILD),)
obj-$(CONFIG_COMPAT_STAGING) += drivers/staging/brcm80211/
obj-$(CONFIG_COMPAT_STAGING) += drivers/staging/ath6kl/
endif
......
modules: $(CREL_CHECK)
 @./scripts/check_config.sh
 #$(MAKE) -C $(KLIB_BUILD) M=$(PWD) modules
 $(MAKE) -C $(KLIB_BUILD) O=${KERNEL_OBJ_DIR}  M=$(PWD) modules
 @touch $@

select-driver网上也有很多patch编译时可以参考。至少./scripts/driver-select   ath9k_htc是可以编译通过的
