1.修改bsp里的Kconfig里面RTT_ROOT地址为：

```c
mainmenu "RT-Thread Project Configuration"

config BSP_DIR
    string
    option env="BSP_ROOT"
    default "."

config RTT_DIR
    string
    option env="RTT_ROOT"
    default "../../../../kernel/rtthread315"

config PKGS_DIR
    string
    option env="PKGS_ROOT"
    default "packages"

source "$RTT_DIR/Kconfig"
source "$PKGS_DIR/Kconfig"
source "board/Kconfig"

config SOC_CM32M
    bool 
    select ARCH_ARM_CORTEX_M4
    default y

config SOC_CM32M101A
    bool
    select RT_USING_COMPONENTS_INIT
    select RT_USING_USER_MAIN
    default y

```

2.修改SConstruct里面RTT_ROOT地址为：

```c
import os
import sys
import rtconfig

if os.getenv('RTT_ROOT'):
    RTT_ROOT = os.getenv('RTT_ROOT')
else:
    RTT_ROOT = os.path.normpath(os.getcwd() + '/../../../../kernel/rtthread315')

sys.path = sys.path + [os.path.join(RTT_ROOT, 'tools')]
from building import *

TARGET = 'rtthread-stm32f2xx.' + rtconfig.TARGET_EXT

DefaultEnvironment(tools=[])
env = Environment(tools = ['mingw'],
	AS = rtconfig.AS, ASFLAGS = rtconfig.AFLAGS,
	CC = rtconfig.CC, CCFLAGS = rtconfig.CFLAGS,
	AR = rtconfig.AR, ARFLAGS = '-rc',
	LINK = rtconfig.LINK, LINKFLAGS = rtconfig.LFLAGS)
env.PrependENVPath('PATH', rtconfig.EXEC_PATH)

if rtconfig.PLATFORM == 'iar':
	env.Replace(CCCOM = ['$CC $CCFLAGS $CPPFLAGS $_CPPDEFFLAGS $_CPPINCFLAGS -o $TARGET $SOURCES'])
	env.Replace(ARFLAGS = [''])
	env.Replace(LINKCOM = ['$LINK $SOURCES $LINKFLAGS -o $TARGET --map project.map'])

Export('RTT_ROOT')
Export('rtconfig')

# prepare building environment
objs = PrepareBuilding(env, RTT_ROOT, has_libcpu=False)

# make a building
DoBuilding(TARGET, objs)
```

3.修改后，可以menuconfig。但是scons --target=mdk5 报错：

```c
$ scons --target=mdk5
scons: Reading SConscript files ...
ImportError: No module named building:
  File "K:\4.cmiot\CM32M101A\1.software\os_sdk\examples\peripherals\rt-thread\proj\SConstruct", line 11:
    from building import *
```
请问，如何修改这个报错。
