I'm on a fresh installation of ubuntu 20 on an OCI VM.Standard.A1.Flex (aarch64).
task clientwasm, "client-wasm":
exec "nim c -d:danger -d:emscripten --cpu:wasm32 --cc:clang --os:linux src/nimstcorepkg/client.nim"
I haven't written any code yet, I'm just trying to get a fresh nimble init hybrid project to compile nim -> wasm.
$ nimble clientwasm
Executing task clientwasm in /home/ubuntu/code/nimstcore/nimstcore.nimble
