##Current Progress We are working on ucore plus for amd64 smp porting. You can chekout the "amd64-smp" branch to see the newest progress of ucore plus.

##Quick Try

1. download or clone ucore plus source code
2. cd ucore
3. make ARCH=i386 defconfig
4. make
5. make sfsimg
6. uCore_run -d obj

##Makefile Cross Compile

set the environment variables:

export ARCH = ?

you can use archs: i386, arm, amd64, mips, or32, um, nios2

export CROSS_COMPILE = ?

(see Makefile in ./ucore)

Kconfig

The top level Kconfig is ./ucore/arch/xxx/Kconfig. You can include other Kconfig

(see ./ucore/arch/arm/Kconfig)

All config option is prefixed with UCONFIG_

Makefile

Supported variables: obj-y, dirs-y

(See ./ucore/kern-ucore/Makefile.build and Makefile.subdir)

Add a new ARCH

In arch/xxx, add Makefile.image and include.mk

***include.mk: define ARCH_INCLUDES and ARCH_CFLAGD, etc.

***Makefile.image: how to generate the executable for your platform.

***Kconfig: your top level Kconfig

***Makefile: recursively add Makefile in your arch directory.
