#Mercury

Mercury is a userspace for the Helios micro-kernel which provides essential low-level userspace services and a framework for hardware drivers.

#Building Mercury

Mercury has the same dependencies as Helios, plus ipcgen, which must be installed to your $PATH when building.

Copy config.def.mk to config.mk and edit it to taste. You need to provide the path to a Helios source tree in the HELIOS variable; it will be automatically compiled when building Mercury.

Run make to build boot.iso, which can be written to a USB stick and booted on hardware, or make run to boot it in qemu. make nographic will boot with a serial console attached to stdin/stdout rather than opening a virtual display; this is generally the more useful approach for testing.
