wasmcloud - getting started

First ensure you have installed the right tools. The easier way to do this is using ubuntu 24.04 that has the right tooling versions. 

Install wash

curl -s https://packagecloud.io/install/repositories/wasmcloud/core/script.deb.sh | sudo bash

apt-get update

apt install wash

Check the version you have installed.

wash --version



Start to install the core components


install sudo apt install build-essential

install rustc 

install golang manually as wasmcloud requires golang version 1.23.

export GO_VERSION="1.23.4"

export GO_ARCH="amd64"

curl -O -L "https://golang.org/dl/go${GO_VERSION}.linux-${GO_ARCH}.tar.gz"

tar -xf "go${GO_VERSION}.linux-${GO_ARCH}.tar.gz"


sudo chown -R root:root ./go

mv -v go /usr/local

export PATH=$PATH:/usr/local/go/bin




Install tinygo


export TINYGO_VERSION="0.34.0"

export TINYGO_ARCH="amd64"

curl -O -L "https://github.com/tinygo-org/tinygo/releases/download/v${TINYGO_VERSION}/tinygo_${TINYGO_VERSION}_${TINYGO_ARCH}.deb"

sudo dpkg -i tinygo_${TINYGO_VERSION}_${TINYGO_ARCH}.deb

export PATH=$PATH:/usr/local/bin

Install WASM tools

cargo install wasm-tools


Once you have all the tools, lets start with creating an hello world program

wash new component hello --template-name hello-world-tinygo

cd hello

Try to do a golang build. 

go build . 

If you have issue, you need to resolve it here. Next, try to do

wash build

wash dev

vllm : Failed to infer device type

Trying to run vllm without gpu will typicaly lands you into this issue. To resolve this issue: we can use set these both. Setting one does not work for me. So i had to configure both settings below:- 1.  environment variable CUDA_VISIBLE_DEVICES = "" 2. in the command line, change to use device cpu and remove  tensor-parallel-size. For example, python3 -m vllm.entrypoints.openai.api_server --port 8080 --model deepseek-ai/DeepSeek-R1 --device cpu --trust-remote-code --max-model-len 4096" References https://docs.vllm.ai/en/latest/getting_started/troubleshooting.html#failed-to-infer-device-type

android studio kotlin source is null error

Image
This org.jetbrains.kotlin.util.FileAnalysisException with a java.lang.IllegalArgumentException: source must not be null is a known issue that can sometimes occur with the Kotlin compiler. It seems to be related to how the compiler analyzes certain source code structures. When this happens, you need to go clean your project and do another rebuild.  For my case, I was trying to test out the databinding = true feature.

gemini cli getting file not defined error

Image
 While trying to run gemini cli on my windows linux subsystem, i bump into this error here - "/Roaming/npm/node_modules/@google/gemini-cli/node_modules/undici/lib/web/webidl/index.js:512 webidl.is.File = webidl.util.MakeTypeAssertion(File)"  "ReferenceError: File is not defined" In Node.js, there’s no built-in File (until very recent Node 20+ with experimental WHATWG APIs). So, unless polyfilled, File is undefined, leading to the ReferenceError. And to resolve this, I had to upgrade to node 22 (might work for node 20) and then I was able to run it.
