In order to compile librespot, you will first need to set up a suitable Rust build environment, with the necessary dependencies installed. You will need to have a C compiler, Rust, and the development libraries for the audio backend(s) you want installed. These instructions will walk you through setting up a simple build environment.
The easiest, and recommended way to get Rust is to use rustup. Once that’s installed, Rust's standard tools should be set up and ready to use.
To ensure a consistent codebase, we utilise rustfmt
and clippy
, which are installed by default with rustup
these days, else they can be installed manually with:
rustup component add rustfmt
rustup component add clippy
Using cargo fmt
and cargo clippy
is not optional, as our CI checks against this repo's rules.
Along with Rust, you will also require a C compiler.
On Debian/Ubuntu, install with:
sudo apt-get install build-essential
On Fedora systems, install with:
sudo dnf install gcc
Depending on the chosen backend, specific development libraries are required.
Note this is an non-exhaustive list, open a PR to add to it!

For example, to build an ALSA based backend, you would need to run the following to install the required dependencies:
On Debian/Ubuntu:
sudo apt-get install libasound2-dev pkg-config
On Fedora systems:
sudo dnf install alsa-lib-devel
The recommended method is to first fork the repo, so that you have a copy that you have read/write access to. After that, it’s a simple case of cloning your fork.
git clone [email protected]:YOUR_USERNAME/librespot.git
Once your build environment is setup, compiling the code is pretty simple.
To build a debug
build with the default backend, from the project root run:
cargo build
And for release
:
cargo build --release
You will most likely want to build debug builds when developing, as they compile faster, and more verbose, and as the name suggests, are for the purposes of debugging. When submitting a bug report, it is recommended to use a debug build to capture stack traces.
There are also a number of compiler feature flags that you can add, in the event that you want to have certain additional features also compiled. The list of these is available on the wiki.
By default, librespot compiles with the rodio-backend
feature. To compile without default features, you can run with:
cargo build --no-default-features
Similarly, to build with the ALSA backend:
cargo build --no-default-features --features "alsa-backend"
Assuming you just compiled a debug
build, you can run librespot with the following command:
./target/debug/librespot
There are various runtime options, documented in the wiki, and visible by running librespot with the -h
argument.
Note that debug builds may cause buffer underruns and choppy audio when dithering is enabled (which it is by default). You can disable dithering with --dither none
.
