Question

I have an extern code written in C in my C++ project in MS VS 2010. It comes with .h and .c files and I use include like this:

extern "C"{
#include "Extern\libname.h"
}

It worked nice. Then I read Google C++ style guide and removed all entries of

using namespace std;

replaced them with just

std::whatINeed

everywhere.

And the error showed up –

error C2065: 'FILE' : undeclared identifier

in the header of extern library. And then I move cursor to the word “FILE” in that code, there is

tydef _iobuf FILE

What should I add into my code to fix it? I don’t want to change extern code because it can be updated and I will be forced to add my fixes on every update. Also, I am sure that there is a simple bug caused by me.

Answer 1

add

#include <cstdio>

above you include.
