This guide will walk you through the requirements needed to build dotnet/runtime on macOS. We'll start by showing how to set up your environment from scratch.
These instructions were validated on macOS 10.15 (Catalina).
Install Apple Xcode developer tools from the Mac App Store (link).
Building dotnet/runtime depends on several tools to be installed. You can download them individually or use Homebrew for easier toolchain setup.
Install the following packages:
- cmake 3.15.5 or newer
- icu4c
- openssl 1.1
- pkg-config
- python3
- ninja (optional, enables building native code with ninja instead of make)
You can install all the required packages above using Homebrew by running this command in the repository root:
brew bundle --no-lock --file eng/Brewfile
