customized linker scripts, simulator support is currently limited to x86 and

Open a (Cygwin) terminal, change to your checkout directory and type:
|

> make menuconfig

|

This starts a curses based text interface for configuring certain aspects of
|
||||
your target platform. Be careful if you use an IDE like Eclipse to manage the
|

build, as integrated terminal emulators tend to choke on curses generated shell

output. Make sure that 'make menuconfig' has been run at least once in an
|

ordinary terminal emulator after a fresh checkout or after issuing 'make

mrproper'.

In case you build on BSD, just use 'gmake' instead of 'make'. This starts an

Ncurses based text interface for configuring certain aspects of your target
|

platform. After a fresh checkout, the first thing you do is to load a profile
|
||||
with sane defaults. In the menuconfig interface, select 'Load a Default
|
||||
Configuration' and choose a preset. After hitting enter, the main menu returns
|
||||
immediately. You can either tune your configuration or just exit (choose 'Yes'
|
||||
at the confirmation dialog to save your stuff).

To build for the actual target platform, just type:

Please keep in mind that the simulator is NOT an emulator. All it does is
