This PR introduces a `codex-utils-cargo-bin` utility crate that wraps/replaces our use of `assert_cmd::Command` and `escargot::CargoBuild`. As you can infer from the introduction of `buck_project_root()` in this PR, I am attempting to make it possible to build Codex under [Buck2](https://buck2.build) as well as `cargo`. With Buck2, I hope to achieve faster incremental local builds (largely due to Buck2's [dice](https://buck2.build/docs/insights_and_knowledge/modern_dice/) build strategy, as well as benefits from its local build daemon) as well as faster CI builds if we invest in remote execution and caching. See https://buck2.build/docs/getting_started/what_is_buck2/#why-use-buck2-key-advantages for more details about the performance advantages of Buck2. Buck2 enforces stronger requirements in terms of build and test isolation. It discourages assumptions about absolute paths (which is key to enabling remote execution). Because the `CARGO_BIN_EXE_*` environment variables that Cargo provides are absolute paths (which `assert_cmd::Command` reads), this is a problem for Buck2, which is why we need this `codex-utils-cargo-bin` utility. My WIP-Buck2 setup sets the `CARGO_BIN_EXE_*` environment variables passed to a `rust_test()` build rule as relative paths. `codex-utils-cargo-bin` will resolve these values to absolute paths, when necessary. --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

npm i -g @openai/codex
or brew install --cask codex
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager. If you use npm:
npm install -g @openai/codex
Alternatively, if you use Homebrew:
brew install --cask codex
Then simply run codex to get started:
codex
If you're running into upgrade issues with Homebrew, see the FAQ entry on brew upgrade codex.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
Using Codex with your ChatGPT plan
Run codex and select Sign in with ChatGPT. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Team, Edu, or Enterprise plan. Learn more about what's included in your ChatGPT plan.
You can also use Codex with an API key, but this requires additional setup. If you previously used an API key for usage-based billing, see the migration steps. If you're having trouble with login, please comment on this issue.
