more than just the networking code.
To build this package you need a current RTEMS tool set for your architecture,
and a recent RTEMS kernel for your BSP configured with networking disabled

build procedure.

can skip to step 5 of the build procedure.
Building and Installing LibBSD
------------------------------
The following instructions show you how to build and install RTEMS Tools and
RTEMS kernel for your BSP in separate paths. Using separate paths for the tools
and BSPs lets you manage what you have installed. If you are happy with a
single path you can use the same path in each stage.
The following instructions show you how to build and install the RTEMS Tool
Suite for the `arm` target, the RTEMS kernel using the
`arm/xilinx_zynq_a9_qemu` Board Support Package (BSP), and the LibBSD for this
BSP.
The Waf build support for RTEMS requires you provide your BSP name as an
architecture and BSP pair. You must provide both or Waf will generate an error
message during the configure phase.
We will build an Xilinx Zynq QEMU BSP using the name

[1] It is good practice to keep your environment as empty as possible. Setting
paths to tools or specific values to configure or control a build is
dangerous because settings can leak between different builds and change
what you expect a build to do. The Waf tool used here lets you specify on
the command line the tools and RTEMS paths and this is embedded in Waf's
configuration information. If you have a few source trees working at any
one time with different tool sets or configurations you can easly move
between them safe in the knowledge that one build will not infect another.
