2 years ago That's strange. When I added UWP support recently, I definitely had everything compiling on Windows 10 with the newest devkitPro. I use a VM without anything else installed, aside from Visual Studio 2019 and JetBrains IDEs. It does look like it could be an issue with platform detection, and I did struggle getting the socket APIs to play nicely for both Unix and Windows, so maybe some of the ifdefs aren't working as intended.
Looking at the stack traces, it looks like the Windows APIs are being used rather than the Unix ones, so that's fine. The conversion errors seem to indicate that different function signatures are present, so potentially different compiler settings or different headers being included. I see sys/socket.h is being included in addition to winsock2.h, and it looks like curl.h is the culprit, so that's probably causing the duplicate definitions. Seems like there are dev environment differences, since including curl didn't cause any errors for me. Commenting out the curl code might resolve it.
The UWP build uses the Visual Studio compiler, so that one probably wouldn't have the same issue.

So, i think saying small in #1 was a understatement.
Info
Windows 10 Latest version of msys2/mingw64/gcc
Problem
When i execute the run task, the transpile task works correctly, but when it moves into the actual compiling, it compiles all the way until the natives.cpp file, in where it fails with a bunch of errors:

It's mostly caused by duplicate definitions of certain things in windows and cygwin headers, which to my understanding shouldn't happen because of the ifdef platform detection, but that's just my theory. The rest of errors can be easily fixed by casting, which should be no big deal.
I think the errors might just be caused by the compiler being too aggresive, so putting a extra flag might solve it, though i haven't tested it yet.
