poka-IT · 2022-05-02T17:50:54Z

I can't build the exemple on windows. I tried to clean, pub get, delete windows folder and let vscode rebuild it, still same issue:

Launching lib\main.dart on Windows in debug mode...
Nuget.exe not found, trying to download or use cached version.

I reopen this because I still have the problem, not sure what happen.
I had to download nuget.exe et put it in C:\Windows\system32 manually, so I don't have Nuget.exe not found, trying to download or use cached version. warning anymore, but still the rest.

poka-IT · 2022-05-05T16:45:01Z

I don't have the issue with v0.20.1, but only with 1.0.0-rc.2.
Still blocked on this, I tried tones of things, I don't understand.

Ok I found a "solution" by editing the file build\windows\packages\Microsoft.Windows.ImplementationLibrary\include\wil/cppwinrt.h:

Commented line 78 to 84:

// #ifdef CPPWINRT_VERSION
// // Prior to C++/WinRT "2.0" this header needed to be included before 'winrt/base.h' so that our definition of
// // 'WINRT_EXTERNAL_CATCH_CLAUSE' would get picked up in the implementation of 'winrt::to_hresult'. This is no longer
// // problematic, so only emit an error when using a version of C++/WinRT prior to 2.0
// static_assert(::wil::details::major_version_from_string(CPPWINRT_VERSION) >= 2,
//     "Please include wil/cppwinrt.h before including any C++/WinRT headers");
// #endif

Commented line 100 to 103:

// #if __WI_CONFLICTING_WINRT_EXTERNAL_CATCH_CLAUSE
// static_assert(::wil::details::major_version_from_string(CPPWINRT_VERSION) >= 2,
//     "C++/WinRT external catch clause already defined outside of WIL");
// #endif

After that, seems to work...

I have the same problems when using audioplayers: ^1.0.0-rc.4, and I followed the instructions mentioned above, it worked. But it seems like a hack.

zappaz00 · 2022-08-08T15:30:42Z

I have the same issue on 1.0.1. I think it related with Windows SDK enviroment because on the one PC it builds correctrly but on the another I have this error. And SDK versions maybe different. I check versions later and write it

Gustl22 · 2022-09-27T17:19:43Z

@poka-IT can I close this? Seems like it's dependent on the Windows SDK?

Yes, thank you

I've tried to update win 10 SDK, but I failed, I even update Visiual Studio to 2022, but it didn't work.
It always said:

Nuget.exe not found, trying to download or use cached version.

After that, I try to download Nuget.exe manually from following URL:

https://dist.nuget.org/win-x86-commandline/latest/nuget.exe

I found that I couldn't download, I think it's the point:
I cannot download it directly.
I have try to download this file by other methods.
After I put it in the folder: /windows/system32/, I got this error:

@todoline-plus-plus please see #1319
Its only a warning, it should compile anyways.

@todoline-plus-plus please see #1319 Its only a warning, it should compile anyways.

It build failed, it cannot continue to debug the code.
I have compared the screenshot you've shown in [#319 ] (#1319).
I found that there are no Individual components in my system to select, what should I do next?

@todoline-plus-plus just asking the same questions:

Did you install Visual Studio or Visual Studio Build Tools 2022?
Which version of VS or Build Tools do you use?
Did you select the Desktop development with C++ and all default components?
I upgraded to Win11 SDK 10.0.22621.0. But Win10 SDK 10.0.19041.0 is also working fine.

here is the picture:

It means that there no items:

Windows Universal C Runtime
C++/WinRT

See error code above:

Microsoft.Windows.ImplementationLibrary\include\wil/cppwinrt.h(271,5)

I think it lost C++/WinRT, then cause the error.
