Error with std::byte

[vital bolt]

Hi guys, I'm getting an error with std::byte, I have the right includes

#include <iostream>
#include <cstddef>

but it gives me that error saying that there is no byte member
what can I do?

I read in internet that byte member was added at C++17, but the code was made in that version and is compiling with that version (using Makefile)

CC is the compiler command, not the flags... I'm not sure if that would work

can you show your full makefile

Actually, is this vscode? try compiling with make

this is probably just a config issue in vscode

[vital bolt]

i'm compiling using make at the terminal yes

and gives me this error too

[hushed roost]

That looks fine... do g++ --version

[hushed roost]

that's a really old version of the compiler

it probably doesn't support those C++17 changes

(17 means 2017.... your copyright says 2016 😄 )

You probably installed the original mingw project, which has been discontinued

[vital bolt]

this is the makefile

ohh

@vital bolt https://github.com/niXman/mingw-builds-binaries/releases
Download the
x86_64-13.2.0-release-posix-seh-ucrt-rt_v11-rev0.7z version is what you should get I believe

MinGW-w64 is the continued project

and is updated to GCC 13

and just go into where you previously installed mingw and replace it

[vital bolt]

hmm

ok let me try

btw, why posix one?

and not windows?

ok it worked!!!

thank you so much :3

[hushed roost]

comes with stuff like threads

[vital bolt]

oh ok

[hushed roost]

glad you got it working and your compiler updated 🙂

Note that you can even use C++20 now too

[vital bolt]

yeah!

we usually use at classes the C++17 but I was using CLion at that time (and it uses the inbuilt mingw). So now that I went to another project and come to VSCode I forgot about the version xD
