Dear Cenk, Thank you for important information about my RIOT-2016.10 problem. As you say, I found core dump file, but it was not generated. Next step, I ran "PORT0=tap0 make debug" , and start RIOT program by typing 'run' in the (gdb) shell. The following messages are displayed.
Starting program: /home/user/Desktop/RIOT-2016.10/examples/gnrc_networking/bin/native/gnrc_networking.elf tap0 RIOT native interrupts/signals initialized. LED_RED_OFF LED_GREEN _ON RIOT native board initialized. RIOT native hardware initialization complete. Program received signal SIGSEGV, Segmentation fault. 0x00000000 in ?? () In the "signup.h" file, 'SIGSEGV' means 'Segmentation violation'. It is a only information in the (gdb) shell display. What does '0x00000000 in ?? ()' mean ?. Anyway it may be difficult to execute RIOT2016.10 on the Ubuntu 12.04. I have not experienced Vagrant. If all necessary tools are pre-installed, It it helpful for me. I try to install Vagrant.
