You can get the toolchain installer here!

Note: This link stopped working on Firefox (Nov 2023), so the ES team will be troubleshooting it. In the meantime, you can use Chrome to install the toolchain.

1. Open your downloads folder in Finder
2. Locate the package and right-click on it
3. Select "Open"
4. Follow the install wizard prompts

For detailed information on what the toolchain includes, see our Understanding the Toolchain Wiki Page.

If you encounter this popup and don't see an "Open" button, you probably double-clicked or opened the package directly. You'll have to right-click the package in Finder and select "Open" from the context menu.

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

If you get this error, you should be able to resolve it by running: xcode-select --install within your terminal.

This does not install Xcode, nor is Xcode necessary for any Daisy tools.

For other issues, see our dedicated Troubleshooting Wiki Page.

If you see other unrelated errors, or have used another method to install the toolchain you can verify the proper version of the toolchain by running:

arm-none-eabi-gcc --version

The suggested version can be manually downloaded and installed from here. It is v10.3-2021.10
