Building Zed for Linux

Repository

Clone down the Zed repository.

Dependencies

  • Install Rust. If it's already installed, make sure it's up-to-date:

    rustup update

  • Install the necessary system libraries:

    script/linux

    If you prefer to install the system libraries manually, you can find the list of required packages in the script/linux file.

Backend dependencies

This section is still in development. The instructions are not yet complete.

If you are developing collaborative features of Zed, you'll need to install the dependencies of zed's collab server:

Alternatively, if you have Docker installed you can bring up all the collab dependencies using Docker Compose:

docker compose up -d

Building from source

Once the dependencies are installed, you can build Zed using Cargo.

For a debug build of the editor:

cargo run

And to run the tests:

cargo test --workspace

In release mode, the primary user interface is the cli crate. You can run it in development with:

cargo run -p cli

Installing a development build

You can install a local build on your machine with:

./script/install-linux

This will build zed and the cli in release mode and make them available at ~/.local/bin/zed, installing .desktop files to ~/.local/share.

Wayland & X11

Zed supports both X11 and Wayland. By default, we pick whichever we can find at runtime. If you're on Wayland and want to run in X11 mode, use the environment variable WAYLAND_DISPLAY=''.

Notes for packaging Zed

Thank you for taking on the task of packaging Zed!

Technical requirements

Zed has two main binaries:

  • You will need to build crates/cli and make its binary available in $PATH with the name zed.
  • You will need to build crates/zed and put it at $PATH/to/cli/../../libexec/zed-editor. For example, if you are going to put the cli at ~/.local/bin/zed put zed at ~/.local/libexec/zed-editor. As some linux distributions (notably Arch) discourage the use of libexec, you can also put this binary at $PATH/to/cli/../../lib/zed/zed-editor (e.g. ~/.local/lib/zed/zed-editor) instead.
  • If you are going to provide a .desktop file you can find a template in crates/zed/resources/zed.desktop.in, and use envsubst to populate it with the values required. This file should also be renamed to $APP_ID.desktop so that the file follows the FreeDesktop standards.
  • You will need to ensure that the necessary libraries are installed. You can get the current list by inspecting the built binary on your system.
  • For an example of a complete build script, see script/bundle-linux.
  • You can disable Zed's auto updates and provide instructions for users who try to update Zed manually by building (or running) Zed with the environment variable ZED_UPDATE_EXPLANATION. For example: ZED_UPDATE_EXPLANATION="Please use flatpak to update zed.".
  • Make sure to update the contents of the crates/zed/RELEASE_CHANNEL file to 'nightly', 'preview', or 'stable', with no newline. This will cause Zed to use the credentials manager to remember a user's login.

Other things to note

At Zed, our priority has been to move fast and bring the latest technology to our users. We've long been frustrated at having software that is slow, out of date, or hard to configure, and so we've built our editor to those tastes.

However, we realize that many distros have other priorities. We want to work with everyone to bring Zed to their favorite platforms. But there is a long way to go:

  • Zed is a fast-moving early-phase project. We typically release 2-3 builds per week to fix user-reported issues and release major features.
  • There are a couple of other zed binaries that may be present on Linux systems (1, 2). If you want to rename our CLI binary because of these issues, we suggest zedit, zeditor, or zed-cli.
  • Zed automatically installs the correct version of common developer tools in the same way as rustup/rbenv/pyenv, etc. We understand this is contentious, see here.
  • We allow users to install extensions locally and from zed-industries/extensions. These extensions may install further tooling as needed, such as language servers. In the long run, we would like to make this safer, see here.
  • Zed connects to several online services by default (AI, telemetry, collaboration). AI and our telemetry can be disabled by your users with their zed settings or by patching our default settings file.
  • As a result of the above issues, zed currently does not play nice with sandboxes, see here

Flatpak

Zed's current Flatpak integration exits the sandbox on startup. Workflows that rely on Flatpak's sandboxing may not work as expected.

To build & install the Flatpak package locally follow the steps below:

  1. Install Flatpak for your distribution as outlined here.
  2. Run the script/flatpak/deps script to install the required dependencies.
  3. Run script/flatpak/bundle-flatpak.
  4. Now the package has been installed and has a bundle available at target/release/{app-id}.flatpak.

Memory profiling

heaptrack is quite useful for diagnosing memory leaks. To install it:

$ sudo apt install heaptrack heaptrack-gui
$ cargo install cargo-heaptrack

Then, to build and run Zed with the profiler attached:

$ cargo heaptrack -b zed

When this zed instance is exited, terminal output will include a command to run heaptrack_interpret to convert the *.raw.zst profile to a *.zst file which can be passed to heaptrack_gui for viewing.

Troubleshooting

Can't compile Zed

Before reporting the issue, make sure that you have the latest rustc version with rustup update.

Cargo errors claiming that a dependency is using unstable features

Try cargo clean and cargo build.

Vulkan/GPU issues

If Zed crashes at runtime due to GPU or vulkan issues, you can try running vkcube (usually available as part of the vulkaninfo package on various distributions) to try to troubleshoot where the issue is coming from. Try running in both X11 and wayland modes by running vkcube -m [x11|wayland]. Some versions of vkcube use vkcube to run in X11 and vkcube-wayland to run in wayland.

If you have multiple GPUs, you can also try running Zed on a different one (for example, with vkdevicechooser) to figure out where the issue comes from.
