linkage error

[powerb23]

Hi,
I was wondering what causes this error:
'isPrime' was declared implicitly 'extern' and later static

if i had my declarations as

static int isPrime(int n){
...
}

int doSomething(int m){
...
if (!isPrime(5))
/* do something */

}

Your help will be appreciated

I guess your prototype says
int isPrime(int n);

Where it should say
static int isPrime(int n);

extern and static are mutually exclusive specifiers.
static means module scope name and extern declare a global (program, inter-module) scope name...
