The is the most natural development environment for NuttX.

Any version of the GCC/binutils toolchain may be used.
|

There is a highly modified <a href="http://buildroot.uclibc.org/">buildroot</a>
|

|
available for download from the
|
||||||
|
<a href="http://sourceforge.net/project/showfiles.php?group_id=189573">NuttX SourceForge</a>
|
||||||
|
page.
|
||||||
|
This download may be used to build a NuttX-compatible arm-elf toolchain under Linux or Cygwin.
|
||||||
|
Additional support for m68k, m68hc11, and m68hc12 is available in the
|
||||||
|
<a href="http://nuttx.cvs.sourceforge.net/nuttx/misc/buildroot/">NuttX CVS</a>.

Also very usable is the Linux environment using the

<a href="http://sdcc.sourceforge.net/">SDCC</a> compiler.
|
||||||
|
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
|
||||||
|
issues if you use parts of NuttX with SDCC that have not been well-tested.

This combination works well too.

It works just as well as the native Linux environment except

that compilation and build times are a little longer.

This is a tougher environment.
|
||||||
|
In this case, the Windows native toolchain is unaware of the the
|
||||||
|
Cygwin <i>sandbox</i> and, instead, operates in the native Windows environment.
|
||||||
|
The primary difficulties with this are:
|
||||||
|
</p>
|
||||||
|
<ul>
|
||||||
|
<li>
|
||||||
|
<b>Pathes</b>.
|
||||||
|
Full pathes 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>
|
||||||
|
</ul>
|
||||||
|
<p>
|
||||||
|
At present, on the Zilog Z16F port uses a native Windows toolchain
|
||||||
|
(the Zilog ZDS-II toolchain).

The primary environmental dependency of NuttX is GNU make.
|
||||||
|
If you have other platforms that support GNU make or make
|
||||||
|
utilities that are compatible with GNU make, then it is very
|
||||||
|
likely that NuttX would work in that environment as well.
|
||||||
|
If GNU make is not supported, then some significant modification
|
||||||
|
of the Make system would be required.
