Dear Friends,
I had downloaded a driver for wireless card 802.11g.
They had mentioned to copy the files (*.c , *.h &
Makefile) under kernal source tree (ie. to make a
directory /usr/src/linux.x.x/driver/net/wireless/xxx).
when Iam compiling the kernal. It compile all files in
../net/wireless/ except my directory 'xxx'.
Is there anything to add in Kernal Makefile ?.
Yes.You need edit the *Makefile* under the
/usr/src/linux.x.x/driver/net/wireless/ directory.Also You need to edit
the* Config.in* inside the same directory to get, "Module Enabling
option" when you do make menuconfig/xconfig. Then you can continue with
default steps from make dep.
Let me see one example like,In Linux-2.4.25 how Cisco/Aironet PCMCIA
802.11 wireless cards driver has implemented.
The driver source code should be placed as below.
*#cp airo_cs.c /usr/src/linux-2.4.25/drivers/net/wireless*
airo_cs.c is not using any seperate .h file. It just using kernel
existing headers like,<linux/netdevice.h>,<asm/io.h>,<pcmcia/cs.h>..etc.
Perhaps,If you have any seperate header files with your driver code, you
need to copy that header files,inside the /usr/src/linux-2.4.25/include/
directory.Then give apropriate path in the driver souce code ( example
if header file airo_cs.h is inside the include/linux/drivers/wireless
directory, then you need to edit in source code as
#include<linux/drivers/wireless/airo_cs.h>)
Edit /usr/src/linux-2.4.25/drivers/net/wireless/Makefile and add this
line as,
*obj-$(CONFIG_AIRO_CS) += airo_cs.o airo.o
*Edit /usr/src/linux-2.4.25/drivers/net/wireless/Config.in and* *add
this lines as,*
# If Pcmcia is compiled in, offer Pcmcia cards...
if [ "$CONFIG_PCMCIA" != "n" ]; then
comment 'Wireless Pcmcia cards support'
dep_tristate ' Hermes PCMCIA card support' CONFIG_PCMCIA_HERMES
$CONFIG_HERMES
tristate ' Cisco/Aironet 34X/35X/4500/4800 PCMCIA cards' CONFIG_AIRO_CS
fi
*These line will help you to get "Cisco/Aironet 34X/35X/4500/4800 PCMCIA
cards" option when you do make menuconfig.
If you wish to provide help document associated with this driver when
you do make menuconfig then append your info in
/usr/src/linuc-2.4.25/Documentation/Configure.help file.
Select this module thru, make menuconfig -> Network device support ->
Wireless LAN -> Wireless PCMCIA support.
Finally use the default commands set to complete kernel compilation (
make dep bzImage install modules modules_install).
Thanks,
bharthix.
