The SDCC compiler provides support for the 8051/2, z80, hc08, and other microcontrollers.

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.
