error including undeclared structure

[baxy]

Hi,

please help. I am again abusing c. so i get this error :

stra.c:54:29: error: ‘PS_index’ undeclared (first use in this function)

and the function is

PS_Index = function(PS_index, indexData);

so what i am trying to do is :

first file:

#include <stdio.h>
#include <stdlib.h>

#include "stra.h"

int main (){

char name[] = "index.pif";
uint32_t i = 0;
i= funcIndex (name);

return 0;

}

second file

#include "stra.h"

struct StraIndex *PS_Index = NULL;

funcIndex(char * name){

PS_Index = func(PS_index, indexData);

}

and header file:

typedef struct StraIndex{
	uint32_t s;
	uint32_t *i;
	uint32_t *t;
}StraIndex;

so first i would like to create my stra.o so i compile it as :

gcc -c stra.c -o stra.o

and then i get the above error. What would be the proper way to get a global structure inside my object. is that possible or did i misunderstood something.

thnx

The second file

#include "stra.h"
 
struct StraIndex *PS_Index = NULL;
 
funcIndex(char * name){        <-- Here you need as return type void, but this is not an error, since the default is int.
 
PS_Index = func(PS_index, indexData);   <-- ERROR! Where did you define/declare a function with the name "func"???
 
}

Ok, you want a return type int (now I saw your main).

The error (which he has probably already discovered by now) is simply a misspelling of your variable. It's PS_Index, not PS_index (uppercase not lowercase I).

So you didn't actually post the code you wanted us to check. Instead, you made up and posted some other code. Always post either the original code that actually has the error (the code you posted does not), or, if the program is large, create a small program that still demonstrates the problem.
