Error: [trap] stack overflow
Increase the stack size:
wasm3 --stack-size 1000000 file.wasm
Error: missing imported function
This means that the runtime doesn't provide a specific function, needed for your module execution.
You need to implement the required functions, and re-build Wasm3.
Alternatively, you can use Python to define your environment. Check out
Note: If this happens with
WASI functions like
wasi_snapshot_preview1.*, please report as a bug.
Error: compiling function overran its stack height limit
m3_config.h and rebuilding Wasm3.
Error: [Fatal] repl_load: unallocated linear memory
Your module requires some
Memory, but doesn't define/export it by itself.
This happens if module is built by
Emscripten, or it's a library that is intended to be linked to some other modules.
Wasm3 currently doesn't support running such modules directly, but you can remove this limitation when embedding Wasm3 into your own app.
