ClickOS toolchain

There used to be a toolchain here. Currently this Makefile downloads and builds the necessary libraries for building ClickOS, namely Newlib and Lwip.

Required packages for building on debian are:

• build-essential (automake and etc)
• gcc (up to 4.7)
• texinfo (newlibc)

You also need MiniOS sources. You can get them from https://github.com/sysml/mini-os.

The patches included in this repository are redistributed unmodified from the Xen sources under tools/stubdom.

To build:

$ EXPORT MINIOS_ROOT=<path_to_minios>
$ make all

This will install the libraries in ./$(XEN_TARGET_ARCH)-root/$(XEN_TARGET_ARCH)-xen-elf. Below is what you should expect to see when the build completes

./$(XEN_TARGET_ARCH)-root
    |-- info
    `-- $(XEN_TARGET_ARCH)-xen-elf
        |-- include
        |-- lib
        `-- src

To use this libraries use the --with-newlib and --with-lwip options of configure pointing to $(XEN_TARGET_ARCH)-xen-elf directory.
