including <Windows.h> gives error.

[BigBen]

Hi.

I am including the Windows.h header file in QtCreator, but I get the following error:

In included file: reference to 'byte' is ambiguous

I am not using using namespace std anywhere in my project.

How can I resolve this error?

@BigBen
Not sure where that is coming from, given that you say it's not to do with std::byte.

Start by where do you #include <Windows.h> ? Try putting it before any other #includes, try putting it after all of them, any difference? Try a standalone program with just #include <Windows.h> initially, then add in various Qt includes. Doesn't the error message give any further details about where the error occurs, where byte is being defined? Etc.

@BigBen said in including <Windows.h> gives error.:

reference to 'byte' is ambiguous

thats Microsofts fault their MSVC implementation of std::byte that came with c++17 is ds.

you can, if you're not using byte in your user defined code add #define _HAS_STD_BYTE 0 before the problematic include, that should work.

@JonB Shifting it to before any other includes got rid of the error.

There were no other details in the error messsage.
