C++ file including C header file
- by fdeslaur
I need to include a C header file in my C++ project but g++ throws "not declared in this scope" errors.
I read that i need to use extern "C" keyword to fix it but it didn't seem to work for me.
Here is a dummy example triggering this error.
main.cpp:
#include <iostream>
extern "C"
{
#include "includedFile.h"
}
int main()
{
int a = 2;
int b = 1212;
std::cout<< "Hello World!\n";
return 0;
}
includedFile.h
#include <stdint.h>
enum TypeOfEnum {
ONE,
TWO,
THREE,
FOUR = INT32_MAX,
};
The error thrown is :
$> g++ main.cpp
In file included from main.cpp:4:0:
includedFile.h:7:9: error: ‘INT32_MAX’ was not declared in this scope
FOUR = INT32_MAX,
I saw on this post that I may need #define __STDC_LIMIT_MACROS without any success.
Any help is welcome!
