error de compilación en el proyecto de C++ con códigos C y C++

He creado un proyecto de C++ donde utilizar los códigos C y C++ y tienen algunos problemas con cabeceras ... OK, tengo 3 códigos:error de compilación en el proyecto de C++ con códigos C y C++

basicOCR .cpp

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

#include "preprocessing.h" 
#include "basicOCR.h"

preprocessing.c

#include <stdio.h> 
#include <ctype.h> 
#include <math.h> 

#include "preprocessing.h"

MAIN.C

#include <stdio.h> 
#include <ctype.h> 

#include "basicOCR.h"

y mi 2 propios archivos de cabecera:

basicOCR.h

#include <stdio.h> 
#include <ctype.h>

preprocessing.h

#include <stdio.h> 
#include <ctype.h>

Cada vez que intento compilar un proyecto, que compila basicOCR.cpp sin ningún problema, pero preprocessing.c y main.c me dan errores de sintaxis en cstdlib y xstddef. Sé que son bibliotecas C++. Leí esto How to mix C and C++

e intenté casi todo, pero no funcionó.

¿No nos puede dar los mensajes de error? – Eregrith

Olvidaste hacer una pregunta. También sería bueno mencionar los mensajes de error exactos que recibe; de lo contrario, tendríamos que adivinar, y adivinar tiene una tasa de error notoriamente alta. – Jon

Además, nunca '# include' un encabezado de sistema dentro del suyo, excepto si necesita definiciones de tipo específicas – Eregrith

tengo esa. La solución a esto era hacer clic con el botón derecho en cada código C y Propiedades> C/C++> Avanzado> Compilar como y verificar compilar como código C++ (/ TP)

Una mejor solución sería usar el.extensión de archivo cpp - y luego visual studio la compilará automáticamente usando el compilador C++. Al usar la extensión de archivo .c, está dando a entender que quiere el compilador de C, y por eso tiene que anularlo explícitamente. – Rob

O, como se menciona aquí: http://stackoverflow.com/a/6086702/376240, puede establecer la configuración "Compilar como código C++" en las propiedades del proyecto solo una vez. Esto es mejor que configurarlo para cada archivo C individual. – noumenon

Parece que vc usa encabezados C++ para el código c.

Esto no responde la pregunta, pero ¿por qué no utilizar C++? La única vez que necesita C es cuando desea ser compatible con diferentes versiones de compiladores diferentes, lo que ocurre cuando construye una arquitectura de complemento. En este caso se declara prototipos de plug-in en un "SDK" encabezado así:

#ifndef __SDK_H 
#define __SDK_H 

#ifdef __cplusplus 
extern "C" 
    { 
#endif 
    __declspec(dllexport) return_type calling_convention function_name(parameters); 

#ifdef __cplusplus 
    } 
#endif 

#endif

A continuación, puede compilar su plugin.c que debe contener lo siguiente:

#include "sdk.h" 

return_type function_name(parameters) 
    { 
    /*Do stuff here*/ 
    }
