It seems cmake will test whether the compiler is usable when generating, and not sure why the native-assets-invoked process cant exit normally.

@dcharkes
would you mind to help and take a look at the failure on windows?

It's strange that running cmake using runProcess (or Process.run, Process.runSync) inside test file is okay, but failing when invoked by dart --enable-experiment=native-assets run on Windows.

steps to reproduce:

• git clone https://github.com/rainyl/native_toolchain_cmake
• cd native_toolchain_cmake
• gh pr checkout 3
• dart run run_cmake_process.dart // okay
• cd examples/add
• dart --enable-experiment=native-assets test test/cmake_builder_test.dart // okay
• dart --enable-experiment=native-assets run bin/add.dart // stucks

P.S., To show the problem concisely, example/add/hook/build.dart is not a real build script, just run the generating command of cmake.

P.S.1, We can just focus on windows, since the build script is not complete, it fails on other platforms, it's expected.

P.S.2, I have tried both stable (Flutter 3.29.0) and master (Flutter 3.30.0-1.0.pre.485) channels, but without luck. flutter doctor:

That's curious. They should use the exact same code-path:

https://github.com/dart-lang/sdk/blob/fb137ff73eb335723144c4de26d5a8bd46198668/pkg/dartdev/lib/src/commands/run.dart#L393-L394

Does this also reproduce on the dart executable from the Dart standalone SDK instead of the Flutter SDK? (Flutter wraps dart.exe in some kind of self-updating-script.)

And if you change the order which one gets stuck?

Thanks for your reply 😄

I have just tried dart sdk downloaded from https://dart.dev/get-dart/archive#stable-channel but without luck.

And if you change the order which one gets stuck?

The order of

1. dart --enable-experiment=native-assets test test/cmake_builder_test.dart // okay
2. dart --enable-experiment=native-assets run bin/add.dart // stucks

doesn't matter, option 1 always okay and option 2 always stucks.

I think this problem is same as dart-lang/native#2077 , so let's discuss there.
