各位，问一个SConscript相关的问题。
我用stm32f407的mcu，把库从1.0升级成1.3，由于最新的库里面有同时支持STM32F427 STM32437等，所以库里面多了sdram的文件stm32f4xx_fmc.c，我需要在SConscript里面通过判断使用的芯片类型去掉该文件的包含，最终库里面的SConscript文件如下
```
Import('rtconfig')
Import('RTT_ROOT')
from building import *

# get current directory
cwd = GetCurrentDir()

# The set of source files associated with this SConscript file.
src = Split("""
CMSIS/Device/ST/STM32F4xx/Source/Templates/system_stm32f4xx.c
""")

src += Glob('STM32F4xx_StdPeriph_Driver/src/*.c')

# 我添加的处理
# STM32F427_437xx  STM32F429_439xx  or  STM32F40_41xxx STM32F401xx
if (GetDepend('STM32F40_41xxx') == True) or (GetDepend('STM32F401xx') == True):
	SrcRemove(src, 'stm32f4xx_fmc.c')

#add for startup script 
if rtconfig.CROSS_TOOL == 'gcc':
     src = src + ['CMSIS/Device/ST/STM32F4xx/Source/Templates/gcc_ride7/startup_stm32f40_41xxx.s']
elif rtconfig.CROSS_TOOL == 'keil':
     src = src + ['CMSIS/Device/ST/STM32F4xx/Source/Templates/arm/startup_stm32f40_41xxx.s']
elif rtconfig.CROSS_TOOL == 'iar':
     src = src + ['CMSIS/Device/ST/STM32F4xx/Source/Templates/iar/startup_stm32f40_41xxx.s']

path = [cwd + '/STM32F4xx_StdPeriph_Driver/inc', 
    cwd + '/CMSIS/Device/ST/STM32F4xx/Include',
    cwd + '/CMSIS/Include']

CPPDEFINES = ['USE_STDPERIPH_DRIVER']
group = DefineGroup('STM32_StdPeriph', src, depend = [''], CPPPATH = path, CPPDEFINES = CPPDEFINES)

Return('group')
```

但是我scons 编译时出错，信息如下：
```

由于对python 一窍不通，所以只能请求大家帮助了，谢谢。
