Ok I hate C.... Compilation Problems with gcc, Please help if you can

[cchen]

I'm having some issues compiling the file with gcc (but it compiles with codewarrior). The errors are :

Any ideas on what the issue here is? Seems to be something with string.h and stdlib.h

What's on lines 1-9?

lines 1-9:

/*
* my name
* my email
* CS 3157
* HW 2
* data.c */

#include <stdio.h>
#include "data.h"

I would suspect something is fubared in data.h.

 

[cchen]

But it compiles in Codewarrior and I've ran the project........

Here's the contents of data.h:

/*
* my name
* my email
* CS 3157
* HW 2
* data.h */

typedef struct {

char *question;
char *answer;
} game2;

typedef struct {

game2 *games[5];
} game;

typedef struct {

char *begin;
char *end;
int questionsasked;
int statistics[5];
// 0 for incorrect, 1 for correct
} player_game;

typedef struct {

char *username;
char *password;
int numgames;
player_game *played[999];
} player;

typedef struct {

int numplayers;
player *player2[999];
} players;

/********* FUNCTION HEADERS**********************/
void printgame(game *thegame);
void printplayers (players *theplayers);
game* readgame();
player* getplayer(char *name, players *playerlist);
int login(players *playerlist);
void readFile(players *playerlist);
void clearMem(players *playerlist, game *gamedata)

At first glance I notice there is no semicolon after the last clearMem.

Simplest way to troubleshoot is to make a simple blah.c file like this and compile it:

#include "data.h"
int main(void) { return 0; }

 

[cchen]

AHHH! the semicolon! stupid codewarrior letting me get away with that
thanks!

Cool. 🙂

Always suspect your own code before suspecting the compiler/tools/etc. 😛
