a simple C code but compile generate many errors in Suse

Question

I write a simple .c file and compile it in my Sesu11.But it has many errors even though it just include a simple printf sentence.I wonder that is it caused by my compile environment is not correct and how to check my environment.Thanks. Here is my C code and the compile result.

    [Linux:/si/usr/hrl]vi hello.c

    #include <stdio.h>

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

Your header files appear to be corrupted. Since you are on Suse, I'd recommend that you remove and then reinstall devel_basis:

 zypper remove devel_basis
 zypper install devel_basis

You should be fine after that!
