I test the compiler with a simple program test.c, the details listed below:

1.

    1)test.c:

        int main()
        {
                return 0;
        }
    2) mb-gcc test.c

    the command is successful and a file called "a.out" appear

2.

  1)test.c

        #include <stdio.h>

        int main()
        {
                printf("hello, world");
                return 0;
        }

    2) mb-gcc test.c

    the error message are as follows:

========================================================

I am a beginer in this area. Can anyone tell me how to solve the problem. What should I do with include files?

 

Thank you
