I compile the package openobex as follows:
step1.Compile the openobex package by default:
      #./configure
      #make
      #make install
At the present, there is  libopenobex.a and libopenobex.so  in  /usr/local/lib/ ,as well as obex_const.h    and obex.h are in  /usr/local/include/openobex.Now I want to apply them in my application.

step2.'cp' irxfer.c   obex_io.c bex_io.h obex_put_common.c obex_put_common.h of the directory
      <openobex package>/apps to /root/progame

step3. #cd /root/progame
      #gcc -c *.c
      #gcc -o ir_test *.o -I/usr/local/include /usr/local/lib/libopenobex.a

But errors are coming:

  /usr/local/lib/libopenobex.a(obex_transport.o)(.text+0x48f): In function `obex_transport_write':
  obex_transport.c: undefined reference to `usb_bulk_write'
  /usr/local/lib/libopenobex.a(obex_transport.o)(.text+0x53b): In function `obex_transport_read':
  .......
  .......
  /usr/local/lib/libopenobex.a(usbobex.o)(.text+0x862):usbobex.c: undefined reference to    'usb_release_interface'
  /usr/local/lib/libopenobex.a(usbobex.o)(.text+0x86e):usbobex.c: undefined reference to `usb_close'
  /usr/local/lib/libopenobex.a(usbobex.o)(.text+0x880):usbobex.c: undefined reference to `usb_close'
  collect2: ld 返回 1

if i run like this,instead of what i do in the STEP_3 above:
   #gcc -o  ir_test *.o -Wl,-Bstatic  -I/usr/local/include -L/usr/local/lib -lopenobex
there is still a error:
     /usr/bin/ld: cannot find -lgcc_s
      collect2: ld 返回 1
Can anyone tell me why and how i should correct the error?Thank you!
