Error C2450 - MC9S12C64

Mickalechenko — Mon, 20 Oct 2008 22:24:24 GMT

Hello, I need help to solve a error C2450 that gives me this code.
The complete message of the error is: Error : C2450: Expected: ; = ,
                                                                TratamentoDePassagens.c line 19

Thank you in advance for the help...

The microcontroller that use is: MC9S12C64
The code is:
#include "TratamentoDePassagens.h"
#include "TDS_TratamentoVolta.h"
#include "DefinicoesGLobais.h"
#include "Persistencia.h"
#include "TDS_Auxiliar.h"
#define TAMANHO_DO_DADO_2 4

unsigned char proximidadeEntrePassagens = PASSAGENS_PROXIMAS;
unsigned char regioesDePassagem[TAMANHO_DO_DADO_2] = {REGIAO_DISTANTE, REGIAO_DISTANTE, REGIAO_DISTANTE, REGIAO_DISTANTE};
unsigned char vetAbaixoDoLimiarDeDistorcao[] = {0, 0, 0, 0};
unsigned int vetInstantesDeEntrada[] = {0, 0, 0, 0, 0, 0, 0, 0};

unsigned char picos[TAMANHO_DO_DADO_2] = {0, 0, 0, 0};

extern T_PASSAGEM *pPassagemTerminada; // ******** HERE THE ERROR APPEARS !!!!! *******

extern unsigned char limiarDeRegiaoProxima[];

As tip, I would check the preprocessor output.

Thank you for the response, I was where you said to me (Project - > preprocess) And the error did not appear, but it appears if I compile.

It will be a error of writing code, or a error in the configuration of the codewarrior?

THANKS AGAIN

The idea was to look at the location in the preprocessor and see if anything got replaced.
T_PASSAGEM maybe a macro defined to something unexpected.
Given the error message and the source code, T_PASSAGEM must be a known type at the location it the error occurs. Search in the preprocessor file backwards and make sure it is a known typedef (and not just a known struct tag, for example. For those "struct T_PASSAGEM" is needed).

Good days, thanks for your help. I saw the output of the preprocesador and it gives this

/**** FILE 'C:\PRJTs\CP20\CP20v02\CODIGO\TratamentoDePassagens.c' */

/*       12 */ unsigned char proximidadeEntrePassagens = 0 ;

/*       35 */ {
                  ..... more code

In the project that contains many related files and is another file that contains T_PASSAGEM and also it gives error.
I comment that I must only correct the code (I did not do it), my question is: exists some form to declare T_PASSAGEM within these same archives where gives the error?

//This is a part of the other file
static byte statusPar[TAMANHO_DO_DADO_2];
static T_PASSAGEM bufPassagem[TAMANHO_BUF_PASSAGEM]; // HERE
byte bufPassagemIndex;
T_PASSAGEM *pPassagemTerminada;
T_PASSAGEM* pPassagem[TAMANHO_DO_DADO_2];
T_PASSAGEM *pPassagemCorrente = NULL;
T_PASSAGEM *pPassagemAnterior;
static byte infoPassagemAnterior;
static T_PASSAGEM passagemAnterior;

Thank for your response

To me it seems as if the compiler can't find the type declaration.

Does every file have access to the h-file where T_PASSAGEM is declared? Does that h-file have header guards? What does the declaration look like?

Daniel and Lundin thank you very much for the help.

I find in the another file the definition of the T_PASSAGEM !!!!

typedef struct
{
    byte indiceTemporal;
    byte bufPar[TAMANHO_DO_DADO_2];
    byte sentidos;
    byte _1oEstado;
    byte ultimoEstado;
    word tempoDesdeUltimaPassagem;
    byte bufPicos[TAMANHO_DO_DADO_2];
} T_PASSAGEM;
