Compiling with rtems-libbsd

[mfg]

Hello guys,

Thank you Chris for the reply, but I think I'm doing something wrong 
before the step that you describe to me.

I want to do my own program using the new bsp (I can use the compiled 
examples without problems (atleast dhcpcd01)) but when I try to compile 
there are unreference errors like

/home/marco/Desktop/Proyecto/prueba13/test_main.c:249: undefined 
reference to `rtems_bsd_setlogpriority'
/home/marco/Desktop/Proyecto/prueba13/test_main.c:276: undefined 
reference to `rtems_bsd_initialize'
o-optimize/test_main.o: In function `default_network_ifconfig_lo0':
/home/marco/Desktop/Proyecto/prueba13/test_main.c:79: undefined 
reference to `rtems_bsd_command_ifconfig'

I installed and configured the rtems-libbsd again but it's the same.

For example, the funtion ”tems_bsd_setlogpriority” is defined in lane 
250 of bsd.h 
(/arm-rtems4.12/xilinx_zynq_zedboard/lib/include/rtems/bsd/bsd.h) and I 
include that file in my program (#include <rtems/bsd/bsd.h>).

Is the bsp not enough?
I assumed in the last step of waf (waf install),  all files that we 
need are copied:
+ install 
/home/marco/Prueba-rtems-libbsp3/sandbox/rtems-4.12/arm-rtems4.12/xilinx_zynq_zedboard/lib/libbsd.a 
(from build/arm-rtems4.12-xilinx_zynq_zedboard/libbsd.a)
+ install 
/home/marco/Prueba-rtems-libbsp3/sandbox/rtems-4.12/arm-rtems4.12/xilinx_zynq_zedboard/lib/include/mghttpd/mongoose.h 
(from rtemsbsd/mghttpd/mongoose.h)
+ install 
/home/marco/Prueba-rtems-libbsp3/sandbox/rtems-4.12/arm-rtems4.12/xilinx_zynq_zedboard/lib/include/bsm/audit.h 
(from freebsd/sys/bsm/audit.h)
...

Do I have to copy manually something more from the rtems-libbsd folder 
to bsp?
Maybe the makefile is wrong, do I need link the libbsd.a library? How?

Thanks in advance
