does this helpful?

from ue5coro.

You're using an old version of VS2022, please try updating. If you cannot, you can comment out that part of the code, it's only a test.

bInnerComplete itself is defined on line 116, and gets to line 121 via two [&] lambda captures in the CORO_R macro on lines 117 and 119; this is a bug in the compiler.
The latest version of VS2022 and Clang both compile this code without a warning.

I pushed a compiler workaround attempt to the test branch, does that help?

from ue5coro.

OK,I delete old toolchain in C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Tools\MSVC,and it can be compiled.
Is there any way to choose verion of toolchain instead of delete them?

from ue5coro.

Not that I know of. You can switch between 2019 and 2022 using BuildConfiguration.xml and there's a blacklist somewhere inside of UBT (MicrosoftPlatformSDK.cs, BannedVisualCppVersions) where you can add your bad toolchain's version if you're running a source build. This won't help you much if you're using the build from the Epic launcher.

I would recommend only using the latest toolchain not just to get the plugin compiled, but also to avoid similar compiler bugs in your code.
