Hi, I'm trying to integrate my c code to simulink.
I made a header file and a source file named file.h and file.c.
and there is a function named function1 and the code is stated below.
function1(void)
{
static double a;
a = a+1;
return a;
}
Next, I made a C caller block and typed like below.
function1();
After that, I ran my code and the error is stated like this.
In line 1:error: 223, function "function1" declared implicitly
| function1();
| ^
How can I solve this error?

you need add double as return type for your function prototype and declaration
double function1(void);
double function1(void)
{
...
}

Oh, sorry, I forgot that in my question..
My code contains return type like below.
in header file
double function1();
in source file
double function1()
{
static double a = 0;
a = a+1;
return a;
}

Thanks for your help:)
