        problem, some pipeline issue that is not handled properly by the gcc 3.4.5 toolchain

      Also very usable is the Linux environment using the

      The SDCC compiler provides support for the 8051/2, z80, hc08, and other microcontrollers.
      The SDCC-based logic is less well exercised and you will likely find some compilation

    <p>
      This is a tougher environment.
      In this case, the Windows native toolchain is unaware of the
      Cygwin <i>sandbox</i> and, instead, operates in the native Windows environment.
      The primary difficulties with this are:
    </p>
    <ul>
      <li>
patacongo's avatar
patacongo committed
        <b>Paths</b>.
        Full paths for the native toolchain must follow Windows standards.
        For example, the path <code>/home/my\ name/nuttx/include</code> my have to be
        converted to something like <code>'C:\cygwin\home\my name\nuttx\include'</code>
        to be usable by the toolchain.
      </li>
      <p>
        Fortunately, this conversion is done simply using the <code>cygpath</code> utility.
      </p>
      <li>
        <b>Symbolic Links</b>
        NuttX depends on symbolic links to install platform-specific directories in the build system.
        On Linux, true symbolic links are used.
        On Cygwin, emulated symbolic links are used.
        Unfortunately, for native Windows applications that operate outside of the
        Cygwin <i>sandbox</i>, these symbolic links cannot be used.
      </li>
      <p>
        The NuttX make system works around this limitation by copying the platform
        specific directories in place.
        These copied directories make work a little more complex, but otherwise work well.
      </p>
patacongo's avatar
patacongo committed
      <p><small>
        NOTE: In this environment, it should be possible to use the NTFS <code>mklink</code> command to create links.
        This should only require a minor modification to the build scripts (see <code>tools/winlink.sh</code> script).
      </small></p>
      <li>
        <b>Dependencies</b>
        NuttX uses the GCC compiler's <code>-M</code> option to generate make dependencies.  These
        dependencies are retained in files called <code>Make.deps</code> throughout the system.
        For compilers other than GCC, there is no support for making dependencies in this way.
        For Windows native GCC compilers, the generated dependencies are windows paths and not
        directly usable in the Cygwin make.  By default, dependencies are surpressed for these
        compilers as well.
      </li>
      <p><small>
        NOTE: dependencies are suppress by setting the make variable <code>MKDEPS</code> to point
        to the do-nothing dependency script, <code>tools/mknulldeps.sh</code>.
        Dependencies can be enabled for the Windows native GCC compilers by setting
        <code>MKDEPS</code> to point to <code>$(TOPDIR)/tools/mkdeps.sh --winpaths $(TOPDIR)</code>.
      </small></p>

      <b>Supported Windows Native Toolchains</b>.
      At present, only the Zilog Z16F, z8Encore, and eZ80Acclaim ports use a non-GCC native Windows
      toolchain(the Zilog ZDS-II toolchain).
      Support for Windows native GCC toolchains (CodeSourcery and devkitARM) is currently implemented
      for the NXP LPC214x, STMicro STR71x, and Luminary LMS6918 ARM ports.
      (but could easily be extended to any other GCC-based platform with a small effort).

      <b>Environment Dependencies</b>.
patacongo's avatar
patacongo committed
      The primary environmental dependency of NuttX are (1) GNU make,
patacongo's avatar
patacongo committed
      (2) bash scripting, and (3) Linux utilities (such as cat, sed, etc.).
      If you have other platforms that support GNU make or make
      utilities that are compatible with GNU make, then it is very
patacongo's avatar
patacongo committed
      likely that NuttX would work in that environment as well (with some
      porting effort). If GNU make is not supported, then some significant
      modification of the Make system would be required.
patacongo's avatar
patacongo committed
    <p>
     <b>GNUWin32</b>.
      For example, with suitable make system changes, it should be possible to
      use native GNU tools (such as those from
      <a href="http://sourceforge.net/projects/gnuwin32/">GNUWin32</a>)
      to build NuttX.
      However, that environment has not been used as of this writing.

        NOTE: One of the members on the <a href="http://tech.groups.yahoo.com/group/nuttx/">NuttX forum</a>
        reported that they successful built NuttX using such a GNUWin32-based, Windows native environment.
        They reported that the only necessary change was to the use the NTFS mklink command to create links
        (see <code>tools/winlink.sh</code> script).
