## Why We want to make it possible for an app-server orchestrator on one OS to control an exec-server on another host running a different OS. In practice this kinda already works if you get lucky and the two hosts have the same path format, but we mangle quite a lot of operations if either end is Windows. We should be able to test the cross-platform interactions for exec-server, but we want to do this fairly soon and need a lightweight option for testing. Using Wine to run the Windows side is far from perfect, but it should give us a decent measure of how well we're handling the basics of paths, process spawning, shell interaction, etc. Future changes will add actual exec-server tests and possibly extensions to the Wine testing environment. ## What To make the cross-target-triple build easy, these tests are added only to the Bazel build. This change adds an x86_64 Wine prebuilt managed by Bazel and some build rules that can set up the needed toolchain transition. The support library for running Wine in a test environment created by the Bazel rules comes with its own basic unit and integration tests. Their primary priority is to make sure we don't leak child processes on developer machines and that we can build and launch a basic hello world binary. ## Validation Confirmed these new tests are running on the [x86_64 bazel ubuntu jobs](https://github.com/openai/codex/actions/runs/27446432302/job/81132356855?pr=27937): ``` //bazel/rules/testing/wine:wine-smoke-test (cached) PASSED in 3.7s //bazel/rules/testing/wine:wine-test-support-unit-tests (cached) PASSED in 15.8s ```
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 want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
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.
