# Install WASIX for C and C++

[wasixcc ](https://github.com/wasix-org/wasixcc) is the C and C++ compiler driver for WASIX. It configures Clang, the WASIX sysroot, and WebAssembly optimization tools for you.

## Install wasixcc

On **macOS or Linux**, run the official installer:

```sh
curl -fsSL https://wasix.cc | sh
```

The installer places wasixcc and its dependencies in `~/.wasixcc`. Follow its instructions to update your `PATH`, or open a new terminal after installation.

See the [wasixcc installation options ](https://github.com/wasix-org/wasixcc#installation) for Cargo-based installation and CI setup.

## Compile your first program

Save this as `hello.c`:

File: `hello.c`

```c
#include <stdio.h>

int main(void) {
    printf("Hello from WASIX!\n");
    return 0;
}
```

Compile it to a WebAssembly module:

```sh
wasixcc hello.c -o hello.wasm
```

For a C++ source file, use `wasix++`:

```sh
wasix++ hello.cpp -o hello.wasm
```

## Run with Wasmer

[Install Wasmer ](https://docs.wasmer.io/install), then run the compiled module:

```sh
wasmer run hello.wasm
```

## Next steps

- Read the [wasixcc usage and build-system guide ](https://github.com/wasix-org/wasixcc#usage) for compiler flags, CMake, and Autotools integration.
- Explore the [C examples](https://wasix.org/docs/language-guide/c/examples.md).
- Browse [WASIX builds](https://wasix.org/builds.md) and the wasinix package collection.
