Identifier uint8_t is undefined - Visual Studio 2017

Question

I get an error with the type definitions. I am working with Visual Studio 2017 and so I included stdint.h for the type definitions. But I still have the Problem that the identifier uint8_t is undefined.

What's the problem?

Works fine on godbolt: https://godbolt.org/g/BYunXA, you'll need to provide more info (and a [mcve]) — UnholySheep, May 15 '18 at 09:03
For C++11 and later the more appropriate header would be ``. — super, May 15 '18 at 09:13
When I get similar errors, it is usually because I have typed `unit` instead of `uint`. Please show the exact compiler message! — Bo Persson, May 15 '18 at 09:38
`` or ``? Prefer the latter, and use the full name, `std::uint8_t`. Note that implementations only provide fixed-width types if it's convenient for them; consider `std::uint_fast8_t` or `std::uint_least8_t` instead, according to your needs. — Toby Speight, May 15 '18 at 09:49

it is defined in "stdint.h", add that on the top of your cpp-file:

#include <stdint.h>

OP stated they did that – UnholySheep May 15 '18 at 09:15

And as the answer is tagged `c++`, the answer should be `#include `. – Mark Ingram May 15 '18 at 09:24
ok, he doesn't defined what c++ exactly he is trying... – PanicMan May 15 '18 at 13:38

I included but it still doesn't work.. Don't know why – Sinem May 15 '18 at 14:29
what type is your project? – PanicMan May 15 '18 at 15:05
I had a similar issue. I resolved that by adding **#include "stdint.h"** to the header file. Mind the order of the **#include**. – NoamG Sep 23 '19 at 09:10
