"D:\work\env t-thread-3.0.4\components\cplusplus\crt.cpp"这个文件在硬盘上是存在，这到底是什么问题呢？

这家伙很懒，什么也没写！

我发现问题所在，是CXX被扩展成"g++“，而不是”arm-none-eabi-g++“。导致问题。但是CC都被正确扩展成”arm-none-eabi-gcc“。rt_config.py文件如下：
_______________________________________________________________________________________________
import os

# toolchains options
ARCH='arm'
CPU='am335x'
CROSS_TOOL='gcc'

if os.getenv('RTT_CC'):
    CROSS_TOOL = os.getenv('RTT_CC')

if  CROSS_TOOL == 'gcc':
    PLATFORM 	= 'gcc'
    EXEC_PATH 	= r'C:\Program Files (x86)\CodeSourcery\Sourcery_CodeBench_Lite_for_ARM_EABI\bin'

if os.getenv('RTT_EXEC_PATH'):
    EXEC_PATH = os.getenv('RTT_EXEC_PATH')

BUILD = 'debug'

if PLATFORM == 'gcc':
    # toolchains
    PREFIX = 'arm-none-eabi-'
    CC = PREFIX + 'gcc'
    CXX = PREFIX + 'g++'
    AS = PREFIX + 'gcc'
    AR = PREFIX + 'ar'
    LINK = PREFIX + 'gcc'
    TARGET_EXT = 'elf'
    SIZE = PREFIX + 'size'
    OBJDUMP = PREFIX + 'objdump'
    OBJCPY = PREFIX + 'objcopy'

DEVICE = ' -Wall -march=armv7-a -mtune=cortex-a8'+\
             ' -ftree-vectorize -ffast-math -mfpu=vfpv3-d16 -mfloat-abi=softfp'
    #DEVICE = ' '
    CFLAGS = DEVICE
    AFLAGS = ' -c' + DEVICE + ' -x assembler-with-cpp -D__ASSEMBLY__'
    LFLAGS = DEVICE + ' -Wl,--gc-sections,-Map=rtthread-beaglebone.map,-cref,-u,Reset_Handler -T beaglebone_ram.lds'

CPATH = ''
    LPATH = ''

if BUILD == 'debug':
        CFLAGS += ' -O0 -gdwarf-2 -Wall'
        AFLAGS += ' -gdwarf-2'
    else:
        CFLAGS += ' -O2 -Wall'

POST_ACTION = OBJCPY + ' -O binary $TARGET rtthread.bin\n' +\
                  SIZE + ' $TARGET \n'

是不是scons有bug啊?!

步骤：
1. 解压rt-thread-3.0.4.tar.gz到env下.
2. 从D:\work\env\sample下拷贝Kconfig文件到D:\work\env\rt-thread-3.0.4\bsp\beaglebone目录下。
3. 进入D:\work\env\rt-thread-3.0.4\bsp\beaglebone目录，右键选择ConEnv Here，进入env命令行
4. 执行scons编译，这时编译成功。
5. 执行menuconfig. 并选择"Support C++ features"，然后保存退出menuconfig.
6. 执行scons编译，结果出错，如下：

7. 修改rt_config.py中CXX定义
——————————————————————————————
    PREFIX = 'arm-none-eabi-'
    CC = PREFIX + 'gcc'
    CXX = PREFIX + 'g++'
——————————————————————————————
修改最后一项CXX为：
——————————————————————————————
    PREFIX = 'arm-none-eabi-'
    CC = PREFIX + 'gcc'
    CXX = 'arm-none-eabi-g++'
——————————————————————————————
再次执行scons编译，错误依旧：
————————————————————————————————
g++ -o "build\kernel\components\cplusplus\crt.o" -c -Wall -march=armv7-a -mtune=cortex-a8 -ftree-vectorize -ffast-math -mfpu=vfpv3-d16 -mfloat-abi=softfp -O0 -gdwarf-2 -Wall -DHAVE_CCONFIG_H -DRT_USING_NEWLIB -I. -Iapplications -Idrivers -ID:\work\env\rt-thread-3.0.4\include -ID:\work\env\rt-thread-3.0.4\libcpu\arm\am335x -ID:\work\env\rt-thread-3.0.4\libcpu\arm\common -ID:\work\env\rt-thread-3.0.4\components\cplusplus -ID:\work\env\rt-thread-3.0.4\components\dfs\include -ID:\work\env\rt-thread-3.0.4\components\dfs\filesystems\devfs -ID:\work\env\rt-thread-3.0.4\components\dfs\filesystems\elmfat -ID:\work\env\rt-thread-3.0.4\components\drivers\include -ID:\work\env\rt-thread-3.0.4\components\drivers\include -ID:\work\env\rt-thread-3.0.4\components\drivers\include -ID:\work\env\rt-thread-3.0.4\components\finsh -ID:\work\env\rt-thread-3.0.4\components\libc\compilers\newlib "D:\work\env\rt-thread-3.0.4\components\cplusplus\crt.cpp"
Exception: [Error 2] : No such file or directory
————————————————————————————————————————————
8. 查看D:\work\env\rt-thread-3.0.4\bsp\beaglebone\SConstruct文件，发现以下定义：
_______________________________________________________________________
env = Environment(tools = ['mingw'],
	AS = rtconfig.AS, ASFLAGS = rtconfig.AFLAGS,
	CC = rtconfig.CC, CCFLAGS = rtconfig.CFLAGS,
	AR = rtconfig.AR, ARFLAGS = '-rc',
_______________________________________________________________________
修改为(添加了其中CXX，对rtconfig不了解，暂时设置为rtconfig.CC)：
_______________________________________________________________________
env = Environment(tools = ['mingw'],
	AS = rtconfig.AS, ASFLAGS = rtconfig.AFLAGS,
	CC = rtconfig.CC, CXX = rtconfig.CC, CCFLAGS = rtconfig.CFLAGS,
	AR = rtconfig.AR, ARFLAGS = '-rc',
_______________________________________________________________________
再次执行scons编译，出现以下问题：

但是前面问题没有了，说明跟安装mingw环境有关

漫漫朔雪 2018-07-09

这家伙很懒，什么也没写！

9. 修改SConstruct，相关部分改为如下：
env = Environment(tools = ['mingw'],
    AS = rtconfig.AS, ASFLAGS = rtconfig.AFLAGS,
    CC = rtconfig.CC, CCFLAGS = rtconfig.CFLAGS,
    CXX = rtconfig.CC, CXXFLAGS = rtconfig.CXXFLAGS,
    AR = rtconfig.AR, ARFLAGS = '-rc',
    LINK = rtconfig.LINK, LINKFLAGS = rtconfig.LFLAGS)

增加CXX和CXXFLGAS。
10. 修改rtconfig.py，增加“CXXFLAGS = CFLAGS”
11. 执行scons编译，仍然如下：
