Closed aitorhh closed 4 years ago

aitorhh commented 4 years ago

Describe the issue wasm not compiling while testing example provided at https://www.graalvm.org/docs/reference-manual/languages/wasm/

Steps to reproduce the issue Please include both build steps as well as run steps

  1. sdk install java 20.0.0.r11-grl
  2. sdk use java 20.0.0.r11-grl
  3. Download the latest wasm: wget https://github.com/graalvm/graalvm-ce-dev-builds/releases/download/20.1.0-dev-20200325_0537/wasm-installable-svm-java11-linux-amd64-20.1.0-dev.jar
  4. gu install --force -L wasm-installable-svm-java11-linux-amd64-20.1.0-dev.jar
  5. Create example floyd.wasm from https://www.graalvm.org/docs/reference-manual/languages/wasm/
  6. wasm --Builtins=memory,env:emscripten loyd.wasm

Describe GraalVM and your environment:

More details After running wasm --Builtins=memory,env:emscripten loyd.wasm:

ERROR: Invalid MAGIC number: 1668180259 should = 1836278016.

When using wasm v20.0.0 from stable release, I get a more detailed stacktrace:

@aitorhh, thank you for the report. The error is reproducible.

olyagpl commented 4 years ago

@aitorhh, there was a change introduced to WASM support in GraalVM. We updated the doc https://www.graalvm.org/reference-manual/wasm/#running-webassembly-programs. It is recommended to built WASM binary must be built using a recent Emscripten version. The Builtins option should point to wasi_snapshot_preview1: wasm --Builtins=wasi_snapshot_preview1 example.wasm. Thanks for reporting the problem!
