Note that the `<target architecture>` will usually be arm or arm64 and the `<ubuntu distro name>` is bionic for 18.04.

Alternatively, use the following Docker image which contains all the software packages and configurations required to cross-compile for ARM `mcr.microsoft.com/dotnet-buildtools/prereqs:ubuntu-18.04-mlnet-cross-arm64-20210519131124-2e59a5f`.

### macOS

macOS 10.13 (High Sierra) or higher is needed to build dotnet/machinelearning. We are using a .NET Core 3.1 SDK to build, which supports 10.13 or higher.

Please note that newer versions of Homebrew [don't allow installing directly from a URL](https://github.com/Homebrew/brew/issues/8791). If you run into this issue, you may need to download libomp.rb first and install it with the local file instead.

Also, libomp version 7.0.0 doesn't have a cask for Big Sur. You can work around this by downloading the libomp.rb file and then calling `brew install libomp.rb --build-from-source --formula`.
