System requirements to build Karabiner-Elements:

• macOS 10.14+
• Xcode 10+
• Command Line Tools for Xcode
• CMake (brew install cmake)

Clone the source from github.

git clone --depth 1 https://github.com/pqrs-org/Karabiner-Elements.git

cd Karabiner-Elements
make package

The make script will create a redistributable Karabiner-Elements-VERSION.dmg in the current directory.

Karabiner-Elements uses some pre-built binaries in the source tree.

• src/vendor/Karabiner-VirtualHIDDevice/dist/*.kext
• src/vendor/Sparkle/Sparkle.framework

Above make package command does not rebuild these binaries.
(These binaries will be copied in the distributed package.)

If you want to rebuild these binaries, you have to build them manually.
Please follow the instruction of these projects.

If you want to build kext in Karabiner-VirtualHIDDevice, macOS requires a valid certificate which be able to sign the built kext.
Unless such certificate, macOS refuses to load the built kext.
Please read a documentation about System Integrity Protection Guide for more details.

(We are including the pre-built kext binary to avoid the restriction that macOS requires a uncommon certificate.)
