"Unsupported ELF header" when running Go-compiled WASM #200

Open

Description

Issue Description

I am trying to run a Go-compiled WASM module (testhyperlight-go.wasm) with hyperlight-wasm, but encounter the following error:

Error: GuestError(GuestError, "Error: failed to parse precompiled artifact as an ELF\n\nCaused by:\n Unsupported ELF header")

This occurs when attempting to load the WASM file in the modified examples/helloworld/main.rs test case (see Reproduction Steps below).


Reproduction Steps

  1. Compile the Go WASM module:

    bash
    GOOS=wasip1 GOARCH=wasm go build -o "testhyperlight-go.wasm"
    package main
     
    //go:wasmexport noReturnCal
    func noReturnCal() {
     result := 0
     for i := 0; i < 100; i++ {
     result += i
     }
    }
     
    func main() {}
  2. Modify examples/helloworld/main.rs to include the new test case:

    fn main() -> Result<()> {
     let tests = [
     (
     "HelloWorld.aot",
     "HelloWorld",
     "Message from Rust Example to Wasm Function".to_string(),
     ),
     (
     "RunWasm.aot",
     "Echo",
     "Message from Rust Example to Wasm Function".to_string(),
     ),
     // New test case (Go WASM)
     (
     "testhyperlight-go.wasm",
     "noReturnCal",
     "Message from Rust Example to Wasm Function".to_string(),
     ),
     ];
     // ... (rest of the test logic)
    }
  3. Run the example and observe the error:

    Result from calling HelloWorld Function in Wasm Module test case 0) is: 0
    Result from calling Echo Function in Wasm Module test case 1) is: Message from Rust Example to Wasm Function
    Error: GuestError(GuestError, "Error: failed to parse precompiled artifact as an ELF\n\nCaused by:\n Unsupported ELF header")
    

Questions

  1. Does hyperlight-wasm currently support WASM files compiled with another compiler?
    • Hyperlight provide wasm-clang-builder to compile C file , but does hyperlight compatible with Go-compiled WASM (with WASI support, such as GOOS=wasip1 GOARCH=wasm go build).
  2. If not, are there any possible modifications that can make hyperlight-wasm work with Go-compiled WASM?
