INSTALLATION
^^^^^^^^^^^^

Download and Unpack:

  Download and unpack the NuttX tarball.  If you are reading this, then
  you have probably already done that.  After unpacking, you will end
  up with a directory called nuttx-version (where version is the NuttX
  version number). You might want to rename that directory nuttx to
  match the various instructions in the documentation and some scripts
  in the source tree.

  That nuttx build directory should reside in a path that contains no
  spaces in the higher level directory names.  For example, under
  Cygwin, your home directory might be formed from your first and last
  names like: "/home/First Last". That will cause strange errors when
  the make system tries to build.

  [Actually, that problem is probably not to difficult to fix.  Some
   Makefiles probably just need some pathes within double quotes]

A Note about Header Files:

  Some toolchains are built with header files extracted from a C-library
  distribution (such as newlib).  For those toolchains, NuttX must be
  compiled without using the standard header files that are distributed
  with your toolchain.  This prevents including conflicting, incompatible
  header files (such as stdio.h).

  Certain header files, such as setjmp.h and varargs.h, may still be
  needed from your toolchain, however.  If that is the case, one solution
  is to copy those header file from your toolchain into the NuttX include
  directory.

  Also, if you prefer to use the stdint.h and stdbool.h header files from
  your toolchain, those could be copied into the include/ directory too.
  Using most other header files from your toolchain would probably cause
  errors.

CONFIGURING NUTTX
^^^^^^^^^^^^^^^^^

"Canned" NuttX configuration files are retained in:

  configs/<board-name>/<config-dir>

Where <board-name> is the name of your development board and <config-dir>.
Configuring NuttX requires only copying three files from the <config-dir>
to the directly where you installed NuttX (TOPDIR):

  Copy configs/<board-name>/<config-dir>/Make.def to ${TOPDIR}/Make.defs
    Make.defs describes the rules needed by you tool chain to compile
    and link code.  You may need to modify this file to match the
    specific needs of your toolchain.

  Copy configs/<board-name>/<config-dir>/setenv.sh to ${TOPDIR}/setenv.sh
    setenv.sh is an optional convenience file that I use to set
    the PATH variable to the toolchain binaries.  You may chose to
    use setenv.sh or not.  If you use it, then it may need to be
    modified to include the path to your toolchain binaries.

  Copy configs/<board-name>/<config-dir>/defconfig to ${TOPDIR}/.config
    The defconfig file holds the actual build configuration.  This
    file is included by all other make files to determine what is
    included in the build and what is not.  This file is also used
    to generate a C configuration header at include/nuttx/config.h.

General information about configuring NuttX can be found in:

  ${TOPDIR}/configs/README.txt
  ${TOPDIR}/configs/<board-name>/README.txt

There is a configuration script in the tools/ directory that makes this
easier.  It is used as follows:

  cd ${TOPDIR}/tools
  ./configure.sh <board-name>/<config-dir>

BUILDING NUTTX
^^^^^^^^^^^^^^

NuttX builds in-place in the source tree.  You do not need to create
any special build directories.  Assuming that your Make.defs is setup
properly for your tool chain, the following steps are all that are
required to build NuttX:

  cd ${TOPDIR}
  make

At least one configuration (eagle100) requires additional command line
arguments on the make command.  Read ${TOPDIR}/configs/<board-name>/README.txt
to see if that applies to your target.

DOCUMENTATION
^^^^^^^^^^^^^

Additional information can be found in the Documentation/ directory and
also in README files that are scattered throughout the source tree.  The
documentation is in HTML and can be access by loading the following file
into your Web browser:

  Documentation/index.html

NuttX documentation is also available online at http://www.nuttx.org.
