[Bluez-devel] sdp_send_req_w4_rsp not accessible

[Julien Campana <juliencampana@yahoo.fr>]

Hi everybody,

I'm trying to extend JBlueZ, which links BlueZ and java, in order to
make it JSR82 compatible (Java Bluetooth Spetification). 

BlueZ uses sdp_record_t structures to store the list of service
attributes and I'm trying to modify it in order to get some Java Objects
(with JNI) instead. 
To do this, I have to re-implement the "sdp_service_search_attr_req"
function. 

But the project do not compile because some sdp fucntions cannot not be
linked. I'm getting the following error message:
/tmp/ccvRmUPO.o(.text+0x158e): In function
`my_sdp_service_search_attr_req(sdp_session_t*, _sdp_list const*,
sdp_attrreq_type_t, _sdp_list const*, _sdp_list**)':
: undefined reference to `sdp_send_req_w4_rsp(sdp_session_t*, char*,
char*, int, int*)'

The function my_sdp_service_search_attr_req has exactly the same
implementation as the official function sdp_service_search_attr_req (for
the moment).

I use the following gcc command (java headers for JNI +
/home/julien/bluez/include to get the "sdp_internal.h" header):

gcc -I /home/java/include -I /home/java/include/linux
-I/home/julien/bluez/include BlueZ.cpp -o ../bin/jbluez -lsdp
-lbluetooth -lstdc++

The function can be found into the installed bluetooth library:
nm --dynamic /usr/lib/libsdp.so.2 | grep sdp_send
00002080 T sdp_send_req
000021c0 T sdp_send_req_w4_rsp

I use debian (Knoppix 3.1 with kernel 2.4.20: I know its an old one),
libsdp 1-5-2, libbluetooth 2-5-1, gcc 3.3 (Debian), 

I've tried to compile the project on three different machines (2 Knoppix
with different kernels and a Suse) and the problem remains.


The same problem occurs with following sdp functions:
sdp_extract_seqtype, sdp_extract_pdu, `sdp_gen_pdu.

Does anybody have an idea?

Thank you for your answers.
