If I don't do any changes as I did . and add line in Kconfig as you told me
make ./drivers/staging/wilc1000/ this working fine for me
but
make ./drivers/staging/wilc1000/linux_wlan.o is creates error. Yes
there are two many ifdef I also agreed with Dan.
You can fetch latest changes from staging . you can create that build
error . Untill then I will follow whatever Dan say :-)
