Compiling hxcpp projects stopped working on Windows (even for empty example)

[MoritzBrueckner]

Describe the bug
When compiling an arbitrary Kha/hxcpp project in Visual Studio 2019 on Windows, the compilation fails. This is even the case for the empty sample project. The last time I compiled to hxcpp was some while ago so I unfortunately can't tell when it worked before.

To Reproduce
Steps to reproduce the behavior:

1. Clone the empty sample project
2. Run Kha/make windows
3. Open the generated .sln file
4. A bunch of errors occur:
   • for (almost?) every .cpp file:
     [...]\Empty\build\windows-build\Sources\src\Main.cpp(2,10): fatal error C1083: Datei (Vorkompilierte Headerdatei) kann nicht geöffnet werden: "x64\Debug\Empty.pch": No such file or directory (the German part means Could not open file (precompiled header file)
   • also, if I open one of the .cpp files from the errors above: Could not open the file "Source": "hxcpp.h" (translated; in regards to #include <hxcpp.h>)

Execution Environment:

• Host system: Windows 10
• Target system: Windows 10
• IDE used: Visual Studio 2019
• Kha revision: a57f47b (current master), unmodified and up-to-date submodules.
• Kha build output:

Can not reproduce the problem. GitHub CI is also looking good.

Looks like this issue has solved itself, I temporarily checked out the latest Kinc master and it works again, even after returning to the version from 3 days ago that didn't work above (which is the current one for the Kinc submodule in this repository). Maybe Git messed with some files locally. I hope I didn't waste too much of your time, thanks a lot for giving it a try!

This issue seems to have repeated. I'm having it, and my buddy is as well. We're working on the EchoSystem https://github.com/jrdoughty/EchoSystem, but I did make a blank kha project using the init from the vs code extention to the same effect.

[RobDangerous]

I have absolutely no idea.

[jrdoughty]

Could it be related to the version of kha in that comes with the extention?

[jrdoughty]

I won't be able to test until tonight (another 8 hrs or so)

[RobDangerous]

Unlikely - still, you should really only use the integrated version for your first test-runs, it's almost always way behind and unsupported.

[jrdoughty]

ok, I'll work to get on the latest and greatest and see if this resolves

[jrdoughty]

That resolved kha building to Windows. I've got other issues now, but that'll be something I try to work through and create a different issue for. It'd be great if the extensions could get another update. Especially krom. I know that's not a painless process though.

[RobDangerous]

The Kha extension gets semi-regular updates which are actually painless but even when it's updated you really shouldn't use it's internal Kha - you can't version it. It is absolutely only intended as a starting point. Treat it like a demo mode.
Krom is totally different story, the problem is not the extension, Krom itself needs some work.
