While I have only looked at this briefly, I can tell you that the main problem stems from this error here:

main.c|75|warning: implicit declaration of function 'get_endereco'|

What this means is that you haven't declared the function get_endereco() at that point of the source file yet, and the compiler can only guess what the return type f the function is. By default, the return type of an undeclared function is assumed to be int, hence the errors immediately following this one:

main.c|75|warning: assignment makes pointer from integer without a cast|
main.c|76|warning: assignment makes pointer from integer without a cast|

The error that comes up after that occurs when you finally do reach the implementation for get_endereco(); because the compiler has already generated a default function return prototype for the function, it gets confused when it then sees the real function return type:

main.c|122|error: conflicting types for 'get_endereco'|

The solution for this (and possibly for several other problems) is to add a function prototype before the functions that call get_endereco(). I would in fact recommend adding prototypes for all of the functions (except main(), which has a pre-defined type), just to ensure that the return types and parameters are correctly known to the compiler beforehand:

void get_equipas(equipa_cabecalho* ponteiro);
void get_jogos(jogo_cabecalho* ponteiro,equipa_cabecalho* ponteiro2);
void cria_lista_equipa(equipa_cabecalho** ponteiro);
void imprime_equipas(equipa_cabecalho * ponteiro);
void cria_lista_jogos(jogo_cabecalho** ponteiro);
Equipa * get_endereco(equipa_cabecalho* ponteiro,char (*nome));
void add_jogo(jogo_cabecalho* ponteiro,equipa_cabecalho *ponteiro2,char eq1,char eq2,int eq1res,int eq2res,int dia,int mes,int ano);
void menu();

This is a good practice in any case, and one you'd do well to get into the habit of.
