how to build c++ project with scons 2.3 visual express 2012?

I try: ``` env = Environment(ENV = {'PATH' : os.environ['PATH'], \ 'INCLUDE' : 'c:\\Program Files (x86)\\Microsoft Visual Studio 11.0\\VC\\include\\', \ 'LIB' : 'c:\\Program Files (x86)\\Microsoft Visual Studio 11.0\\VC\\lib\\'}) ``` but it not working. error message: "cl" is not command ... I found description in scons wiki(http://www.scons.org/wiki/PlatformSpecificNotes#Visual_C.2B-.2B-): If using Microsoft Visual C++, you need to set 'INCLUDE', 'LIB' and 'PATH' in your environment, then import them when you create your 'Environment' object. These will be used to locate the MSVC++ tools and set 'CPPFLAGS' etc. What am I doing wrong? complete sconstruct(it works on ubuntu, and on windows with mingw): ``` import os import sys if ARGUMENTS.get('ndk', 0): current_dir = os.getcwd()#os.path.dirname(os.path.abspath(__file__)) os.environ["NDK_PROJECT_PATH"] = current_dir + '/android-project' os.system("ndk-build") # use V=1 if can't compile for android exit(0) if ARGUMENTS.get('ant', 0): current_dir = os.getcwd()#os.path.dirname(os.path.abspath(__file__)) android_prj_path = current_dir + '/android-project' os.chdir(android_prj_path) os.system("ant debug") # use V=1 if can't compile for android exit(0) VariantDir('obj', 'src', duplicate = 0) if sys.platform == 'win32': if ARGUMENTS.get('msvc', 0) == "1": env = Environment(ENV = {'PATH' : os.environ['PATH'], \ 'INCLUDE' : 'c:\\Program Files (x86)\\Microsoft Visual Studio 11.0\\VC\\include\\', \ 'LIB' : 'c:\\Program Files (x86)\\Microsoft Visual Studio 11.0\\VC\\lib\\'}) else: env = Environment(tools = ['mingw']) env.Append(CCFLAGS = '-U__STRICT_ANSI__') # for boost::program_options on mingw 4.7 env.Append(LINKFLAGS = '-mwindows') env.Append(LIBS = ['mingw32', 'SDL2', 'SDL2main', 'm', 'user32', 'gdi32', \ 'winmm', 'imm32', 'ole32', 'oleaut32', 'version', \ 'uuid', 'glew32', 'opengl32']) else: env = Environment() env.Append(CCFLAGS = '-rdynamic') env.Append(LIBS = ['SDL2', 'pthread', 'm', 'dl', 'GL']) env.Append(CCFLAGS = '-fno-strict-aliasing') # for angelscript compile see doc cur_dir = os.getcwd() env.Append(CCFLAGS = '-I ' + cur_dir) # for boost find in include path env.Append(CCFLAGS = '-g -std=c++0x -Wall -Wfatal-errors') #-msse2 -pg env.Append(LINKFLAGS=[]) # -pg src = Glob('obj/*.cpp') src += Glob('obj/scene2d/*.cpp') src += Glob('obj/pugixml/*.cpp') src += Glob('obj/debug_support/*.cpp') src += Glob('obj/angelscript/*.cpp') src += Glob('obj/scriptarray/*.cpp') src += Glob('obj/scriptstdstring/*.cpp') src += Glob('obj/scriptbuilder/*.cpp') src += Glob('obj/boost_libs_src/program_options/src/*.cpp') src += Glob('obj/boost_libs_src/smart_ptr/src/*.cpp') src += Glob('obj/boost_libs_src/system/src/*.cpp') src += Glob('obj/boost_libs_src/filesystem/src/*.cpp') src += Glob('obj/libwebp/*/*.c') src += Glob('obj/zlib/*.c') src += Glob('obj/libpng/*.c') env.Program(target = 'start', source = src) ```
