Need some help - compiling linux bluetooth drivers

********************************** Please redirect it to the correct
person if you are not the one **************************************
 
Hi,
 
Need a small help.
I am using linux kernel version 2.4.22 with bluetooth support removed.
 
Is it possible to build only the bluetooth part
(/net/bluetooth/Makefile) with this kernel source????
 
That is ; is it possible to create only the bluetooth.o (that includes
hci core files) and install it on my running????
Along with all EXPORT_SYMBOL from syms.c
(Instead of building the whole kernel again)
 
Please guide me in compiling on the /net/bluetooth/Makefile
 
 
ANOTHER QUESTION:(related to BLUEZ source code)
In btusb.c there is a firmware download section. Is it required for all
bluetooth USB drives?????
Is the firmware download code common for all of them????
 
Can I use it without the firmware download part????
 
 
Please let me know.
 
 
Thanks. Regards
Pintu

Hi,
 
I need a help in compiling the linux 2.4.22 code (bluetooth part).
Can you help me here.
 
 
Here is my problem description
==========================
I have a linux system which is running on Linux 2.4.22-ncgl-10.12.1.0
kernel. It is a modified kernel. 
Here the BLUETOOTH part is removed from the kernel. 
(I didnt find - hci_core , hci_conn.o , and other required drivers and
some of the export symbols are missing)
(It report un resolved symbols - "hci_register_dev")
 
I have the 2.4.22-ncgl-10.12.1.0 kernel source with me (on another
system).
Now, I dont want to build the whole kernel again. (This is not possible
as it is in another system under separate path)
 
I wanted to compile only the Bluetooth related path (net/bluetooth/*)
from this kernel source and put all related stuffs on my system.
Is it possible??????? Please let me know the procedure. Please help me
out.
 
That is I wanted to compile all the bluetooth protocol stack related
drivers separately.
Such as - hci_conn.c , hci_core.c, rfcomm.c , l2cap.c , etc, etc
 
Also under net/bluetooth folder I saw there is one file - syms.c that
contains many EXPORT_SYMBOLS.
Please let me know how to use this file to export these symbols on my
box.
(My un resolved symbols are actually present here)
 
Note:
I could able to create hci_core.o etc but I am not able to link syms.c
to export the required symbols.
 
 
Please help me out.
 
 
 
Thanks a lot,
Pintu
