QEMU
^^^^
QEMU is a generic and open source machine emulator and virtualizer. Here are
some links (which are mostly outdated by the time your read this):
Home Page: http://wiki.qemu.org/Main_Page
Downloads: http://wiki.qemu.org/Download
Documentation: http://wiki.qemu.org/Manual
Usage: qemu -nographic -kernel nuttx.elf
Building QEMU:
tar zxf qemu-0.14.0.tar.gz
cd qemu-0.14.0
./configure
make
make install
Cygwin build problems:
Error:
"gcc: The -mno-cygwin flag has been removed; use a mingw-targeted cross-compiler."
Workaround:
None known. It does not seem possible to build QEMU using the Cygwin gcc.
I tried editing configure. Removing the following line will allow QEMU to
configure:
QEMU_CFLAGS="-mno-cygwin $QEMU_CFLAGS"
However, it then fails later during the compilation phase.
Recommendation:
1. Google for "qemu windows download" and download some pre-built QEMU
binaries. I found 0.14.0 here: http://dietpc.org/windows/qemu/, or
2. Try building QEMU with MingGW
Configurations
^^^^^^^^^^^^^^

The "standard" NuttX examples/ostest configuration. This
