Unofficial build of common binaries used by developers of the Internet Computer blockchain.

• Directly built from source.
• Cross-platform (Linux and Mac OS X, both x86_64 and aarch64).
• Mostly statically linked with no extra runtime dependency other than libc.
• Weekly release of latest versions at build time.
• Optionally, a standalone SDK environment for nix-shell.

Usage

Depending on your objective, you can do any the following:

• To build a project, run nix-build -A <project>
• To enter a development environment for a project, run nix-shell -A <project>.shell
• To download the latest pre-built binaries, go to release page.
• To start canister SDK development with latest build, run nix-shell https://github.com/ninegua/ic-nix/releases/latest/download/dfx-env.tar.gz

All you need is a working nix installation on your computer.

Compile-yourself from source

For those who prefer to compile from source:

nix-shell https://github.com/ninegua/ic-nix/releases/latest/download/dfx-env.tar.gz --arg force true

You can use pre-compiled derivations by setting a binary cache (courtesy of cachix) nix-shell -p cachix --run 'cachix use ninegua'.

VSCode/direnv

Assuming you're developing on ic.

1. Make sure you have direnv installed.
2. Clone this repo next to ic.
3. Under ic/rs: run echo "use nix ../../ic-nix/default.nix -A ic.shell" > .envrc.
4. In the same directory, run direnv allow .

If using VSCode, you should also install the direnv vscode extension, to make sure that rust-analyzer will be using the same versions of Rust as your shell.

WARNING

Releases are built against the latest main branches of each project at the time. They may not always work. Please understand the risks before proceed.

Supported projects

• ic
• sdk
• motoko
• agent-rs
• candid
• icx-proxy
• cdk-rs
• dfx-extensions
• ic-repl
• ic-wasm
• idl2json
• vessel

Supported platforms and nixpkgs:

✅︎: builds with no issue
❌: does not build
⍻: builds but binaries have extra dynamic lib dependency to Nix store

Feature:

• Build native binaries with nix-build with glibc.
• Dynamic binaries with minimal dependencies: glibc on Linux, system libs on OS X.
• Build Wasm binaries with nix-build.
• Develop with nix-shell.
• Build release binaries on Github.
• Build and run all tests.

Note that this effort requires no nix support of a project unless it already has.
