How To Install wasm-as on Kali Linux

In this guide, we’ll discuss How To Install wasm-as on Kali Linux. Also, we will demonstrate how to uninstall and update wasm-as.

One-liner install command

For those in a hurry, here's a one-line installation command:

sudo apt-get update && sudo apt -y install binaryen

But if you are interested in the detailed steps with descriptions, the following information is for you.

What is wasm-as and what are the ways to install it?

Before beginning this tutorial, you will need access to a server or computer running Kali Linux. This guide was written specifically with a server running Kali Linux in mind, although it should also work on older, supported versions of the operating system.

Also, make sure you are running a regular, non-root user with sudo privileges configured on your server. When you have an account available, log in as your non-root user to begin.

There are several ways to install wasm-as on Kali Linux. You can use (links are clickable):

In the following sections, we will describe each method in detail. You can choose one of them or refer to the recommended one.

Install wasm-as using apt-get

First, update apt database with apt-get using the following command.

sudo apt-get update

After updating apt-get database, You can install wasm-as using apt by running the following command:

sudo apt -y install binaryen

Install wasm-as using apt

Because wasm-as is available in Kali Linux’s default repositories, it is possible to install it from these repositories using the apt packaging system.

To begin, update apt database with apt using the following command.

sudo apt update

After updating apt database, You can install wasm-as using apt by running the following command:

sudo apt -y install binaryen

Install wasm-as using aptitude

If you want to follow this method, you might need to install aptitude first since aptitude is usually not installed by default on Kali Linux. Update apt database with aptitude using the following command.

sudo aptitude update

After updating aptitude database, You can install wasm-as by running the following command:

sudo aptitude -y install binaryen

How to upgrade (update) a single package wasm-as using apt-get?

First, you will need to update packages index. Run update command as usual:

sudo apt-get update

Next, to upgrade only the wasm-as, e.g. single package, you should use the following format with the apt-get command/apt command:

sudo apt-get --only-upgrade install binaryen

Note that this command will not install any new packages! If you wish to install the package if it doesn't exist you may leave out --only-upgrade part.

How To Uninstall wasm-as from Kali Linux

To uninstall only the wasm-as package you can execute the following command:

sudo apt-get remove binaryen

Uninstall wasm-as and all its dependencies

To uninstall wasm-as and its dependencies that are no longer needed by Kali Linux, you can use the command below:

sudo apt-get -y autoremove binaryen

Remove wasm-as with all configurations and data

To remove wasm-as configuration and data from your system you can run the following purge command:

sudo apt-get -y purge binaryen

Remove wasm-as completely (configurations, data and all of its dependencies)

And lastly, you can run the next command to remove absolutely everything related to wasm-as package, e.g.: configurations, data and all of its dependencies. Just use this command:

sudo apt-get -y autoremove --purge binaryen

Extra info and code examples

Binaryen is a compiler and toolchain infrastructure library for WebAssembly, written in C++. It aims to make compiling to WebAssembly easy, fast, and effective: * Easy: Binaryen has a simple C API in a single header, and can also be used from JavaScript. It accepts input in WebAssembly-like form but also accepts a general control flow graph for compilers that prefer that. * Fast: Binaryen's internal IR uses compact data structures and is designed for completely parallel codegen and optimization, using all available CPU cores. Binaryen's IR also compiles down to WebAssembly extremely easily and quickly because it is essentially a subset of WebAssembly. * Effective: Binaryen's optimizer has many passes that can improve code very significantly (e.g. local coloring to coalesce local variables; dead code elimination; precomputing expressions when possible at compile time; etc.). These optimizations aim to make Binaryen powerful enough to be used as a compiler backend by itself. One specific area of focus is on WebAssembly-specific optimizations (that general-purpose compilers might not do), which you can think of as wasm minification , similar to minification for JavaScript, CSS, etc., all of which are language-specific (an example of such an optimization is block return value generation in SimplifyLocals).


You now have a full guide on how to install wasm-as using apt, apt-get and aptitude tools. Also, we showed how to update as a single package and different ways to uninstall the wasm-as from Kali Linux.
