Hi, I am starting my journey with WAMR, trying to figure out if it would be well suited for our next project. For now, I am trying to comile and run the "hello world" (from here https://wamr.gitbook.io/document/basics/getting-started/on_host). I basically copy/pasted the commands from the "host preparation" and running the program on host. Everything seems to install and compile perfectly, with no error. And at runtime I get:

-> % ./iwasm test.wasm
[21:49:39:153 - 7F08B87FBB80]: warning: allocate 16 bytes memory failed
Exception: allocate memory failed

Any hint on what might be the issue?

Now we have our host set up, we can build our hello world program and run it using WAMR.

May I ask which repo or branch you are using? Since there is no "app-samples" in https://github.com/bytecodealliance/wasm-micro-runtime currently

@Gilles ORAZI currently the default host managed heap size is set 0 when libc wasi is compiled, but the wasm file without libc wasi enabled may require host managed heap to run, could you try iwasm --heap-size=16384 test.wasm?

@Wenyong Huang That works perfectly now. Thank you so much !
