Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.3/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

Running into the same error with Expo 50

[rhenandias]

Same here, with version "expo": "~50.0.14".

I'm not trying to use Expo Go, even after prebuild the npx expo run:android fails to build.

My gradle.properties has the property newArchEnabled=true and I'm using the following code to verify if the new architecture is loaded:

const uiManager = global["nativeFabricUIManager" as keyof typeof globalThis]
  ? "Fabric"
  : "Paper";

console.log(`Using ${uiManager}`);

Before installing the package react-native-webassembly, with this code, the console shows that it is using Fabric, with the nativeFabricUIManager. However, the Metro itself don't shows the Fabric log by default as mentioned in this answer. To enable the new architecture, I followed the steps outlined in this part of the documentation.

Am I missing something?

Upgrading NDK to 23.2.8568313 solves the issue

[jimmydjabali]

Still get the same error, tried many different NDK versions but impossible to make it work

[finloop]

This looks like upstream issue in llvm-project:

• Musttail is causing crash when compiling wasm3 for android armv7-a llvm/llvm-project#57069
• [Bug]: clang-17: error: clang frontend command failed with exit code 70 (use -v to see invocation) android/ndk#1973

In short, tail calls on Arm can only have maximum 4 arguments. There could be a better error message for it in clang, but the source might need to be fixed to make it work.

Source: llvm/llvm-project#73167 (comment)

Looks like this was fixed in llvm/llvm-project#109943
