Hello, I have the same issue, And from what I understood, inet_ntop is not found in ws2tcpip.h because defined preprocessor _WIN32_WINNT variable is not >= 0x0600 Mine is 0x0502 and for now I don't know how to modify/update it.

EDIT 1 : The weird thing is that on other of my computers, _WIN32_WINNT is well defined and I don't have this issue. EDIT 2 : MinGW appears to be the responsible for too low _WIN32_WINNT variable. But I don't know yet how to force it to be higher.

I'm going back over these issues trying to get Windows support as good as I can,

Is this still causing problems?

I'm just trying MinGW for the first time in a long while on Windows 10 with a new install. The library in the develop branch builds and now passes all the unit tests with MSVC and MinGW.

With MinGW, gcc 13.2, it's reporting _WIN32_WINNT as 0x0601, which is Windows 7 (despite this being Win10?)

From an MS web page, it seems to imply that this is supposed to allow you to set the target version of Windows that you want?

https://learn.microsoft.com/en-us/cpp/porting/modifying-winver-and-win32-winnt?view=msvc-170

To modify the macros, in a header file (for example, in targetver.h, which is included by some project templates that target Windows), add the following lines.

#define WINVER 0x0A00 #define _WIN32_WINNT 0x0A00

So declare the macros before you include any Windows header(s) and it will honor what you ask? If it can?

Is this something I should add to the library headers, like in platform.h to specify maybe Vista or Win7 as a minimum? What is the convention for Windows libraries?
