## Apple silicon
Cross-compiling Go applications:
Host/Build: macOS/x86_64
Target: macOS/arm64
On host machine:
Xcode: Install latest Xcode which supports Apple silicon
Go: Install go*.darwin-amd64.pkg (or build go from source) on macOS/x86_64
Set go executable in PATH
Export the following environment variables before cross compiling go apps for macOS/arm64
export SDK_NAME=macosx
export SDK_PATH=$(xcrun --show-sdk-path --sdk $SDK_NAME)
export CGO_ENABLED=1
export GOOS=darwin
export GOARCH=arm64
export CC="$(xcrun -sdk $SDK_PATH --find clang) -arch $GOARCH -isysroot $SDK_PATH"
export CFLAGS="-isysroot $SDK_PATH -arch $GOARCH -I$SDK_PATH/usr/include"
export LD_LIBRARY_PATH="$SDK_PATH/usr/lib"
export CGO_CFLAGS="-isysroot $SDK_PATH -arch $GOARCH"
export CGO_LDFLAGS="-isysroot $SDK_PATH -arch $GOARCH"
Compile the app as below:
$ GOOS=darwin GOARCH=arm64 go build <app>
Copy the generated arm64 executable to target machine (macOS/arm64) and run
