Hi, First time with RIOT Trying to make in native but keep getting following error though I have tried to resolve all build chain dependencies on host

"make" -C /home/riot/RIOT/boards/native "make" -C /home/riot/RIOT/boards/native/drivers "make" -C /home/riot/RIOT/core "make" -C /home/riot/RIOT/cpu/native cc1: warnings being treated as errors In file included from /home/riot/RIOT/sys/include/net/ethernet/hdr.h:27,                  from /home/riot/RIOT/cpu/native/include/netdev2_tap.h:30,                  from /home/riot/RIOT/cpu/native/native_cpu.c:53: /home/riot/RIOT/core/include/byteorder.h: In function ‘byteorder_swaps’: /home/riot/RIOT/core/include/byteorder.h:288: error: implicit declaration of function ‘__builtin_bswap16’ make[2]: *** [/home/riot/RIOT/examples/default/bin/native/cpu/native_cpu.o] Error 1 make[1]: *** [ALL--/home/riot/RIOT/cpu/native] Error 2 make: *** [all] Error 2

Please advice where I'm going wrong.

Thanks, Suvrat

Hey Suvrat,

First time with RIOT

Welcome!

make: *** [all] Error 2

Please advice where I'm going wrong.

We'll need more information. What toolchain are you using (please send the output of "gcc -v"), and which distribution are you using?

Native compile does not go through. I keep getting following error

Please advice. Thanks, Suvrat

Hello Suvrat,

My guess is that your gcc version is too old. According to [1], the `__builtin_bswap16` function was introducedwith gcc version 4.8 for x86(_64).

Coud you try updating your gcc?

Best, Cenk

I already had gcc-4.8.2 so I just changed the soft links via ln But now I am getting the following error "Compiler cc is required but not found in PATH. Aborting." I tried understanding the particular line in makefile but it does not make sense to me.

sudo apt-get install gcc does not help

gcc -v yields the following gcc -v Using built-in specs.
