网上找的：Scons使用MinGW

#SConstruct
import platform
import os

if platform.system() == 'Windows':
    env = Environment(tools = ['mingw'], ENV = os.environ)
    env.PrependENVPath('PATH', 'C:\\Dev-Cpp\\bin')
    env.PrependENVPath('LIB', 'C:\\Dev-Cpp\\lib')
else:
    env = Environment(ENV = os.environ)

env.Program(['main.cpp'], LIBS = libs, LIBPATH=libpath, CCFLAGS=cflags)
