Hello there I am trying to build the examples given as part of the Contiki-2.6 RTOS. The directory path is : contiki/contiki-2.6/examples/ping-ipv6

I am trying to build the example ping-ipv6 for TI's SMARTRF05-EB, the SoC being 2530.

1) contiki/contiki-2.6/examples/ping-ipv6# make TARGET=cc2530dk clean

2) contiki/contiki-2.6/examples/ping-ipv6# make TARGET=cc2530dk

but after executing the above 2 commands I get the following error ..I have just included the last part of information from the huge build output. Please let me know how to resolve it. Please note I am able to build the hello-world example and also the cc2530dk example using the above 2 commands.

It seems it has been a long time since the question is asked, but still...

The short answer is that scanf() function is not supported for the target cc2530dk. Instead of scanf(), uart0_set_input() function from /dev/uart0.h or serial_line_event_message event from dev/serial-line.h libraries should be used to read input from UART.

P.S.: There may be other similar incompatibilities as well even if you fix that.

For platforms that don't have scanf, you may want to edit apps/ping6/ping6.c and set MAC_DEBUG to 1. That way you'll be able to hard-code the IPv6 address you want to ping (in the #if MACDEBUG)
