okay. Sure,
Instead of sys_hello.c I created a new one sys_test.c. So, guys don't
confuse with above sys_hello.c and this time sys_test.c, both are the
same file.
Then after that, I went through all the steps including "make config"
make obj && make config && make -j4
Then it throws this error this time. And, I am not able to understand this.
