For other installation options, visit the [Downloads section](https://www.graalvm.org/downloads/).

To create statically linked applications with Native Image, you require a `musl` toolchain with the `zlib` library.
For the best compatibility, use [musl-1.2.4](https://musl.libc.org/releases/musl-1.2.4.tar.gz) or later.
We recommend building `musl` from [source](https://musl.libc.org/) as shown below:
Use the latest or a recent version of musl (all versions prior and including `1.2.5` are affected by [CVE-2025-26519](https://www.openwall.com/lists/musl/2025/02/13/1)).
The steps to building `musl` from [source](https://musl.libc.org/) are as shown below.
The example assumes you are using [musl-1.2.6](https://musl.libc.org/releases/musl-1.2.6.tar.gz).

```bash
# Specify an installation directory for musl:
export MUSL_HOME=$PWD/musl-toolchain

# Download musl and zlib sources:
curl -O https://musl.libc.org/releases/musl-1.2.4.tar.gz
curl -O https://musl.libc.org/releases/musl-1.2.6.tar.gz
curl -O https://zlib.net/fossils/zlib-1.2.13.tar.gz

# Build musl from source
tar -xzvf musl-1.2.4.tar.gz
pushd musl-1.2.4
tar -xzvf musl-1.2.6.tar.gz
pushd musl-1.2.6
./configure --prefix=$MUSL_HOME --static
# The next operation may require privileged access to system resources, so use sudo
sudo make && make install
