• 编译环境的配置

• 编译选项

env = Environment(CCFLAGS='-O3') 或者 env = Environment() env.Append(CCFLAGS = ['-g','-O3'])

• 头文件路径

env.Append(CPPPATH = ['/usr/local/include/']) #头文件包含路径

或者

env= Environment()

env.AppendENVPath(CPPPATH=['.'])

• 预定义

env.Append(CPPDEFINES=['BIG_ENDIAN']) #预处理定义

env.Append(CPPDEFINES={'RELEASE_BUILD' :'1'}) #包含预处理值定义

env= Environment(CPPDEFINES=["BUILD", "DEBUG=0","LINUX=1"])

• 链接库和路径

env.Append(LIBPATH = ['/usr/local/lib/']) #添加库路径

env.Append(LIBS = ['SDL_image','GL']) #添加需要链接的库

• 编译文件

• 生成可执行程序

Program() buildan executable from one or more object files, or C, C++, D or Fortran sourcefiles

t = env.Program(target='bar',source=['foo.c'], CCFLAGS='$CCFLAGS-g')

Default(t) #设置默认生成的程序

Program(Glob('*.c')) #包含本目录下所有.c文件

Program([Glob('*.c'),Glob('ext/*.c')])

• 生成目标文件

StaticObject()or Object() builds an objectfile; .o in POSIX or .obj in Win32

• 生成静态库

StaticLibrary() buildsa library file; .a in POSIX or .lib in Win32

env= Environment()

env.StaticLibrary(target='foo',source=Split('l1.c l2.c'))

env.StaticLibrary(target='bar',source=['l3.c', 'l4.c'])

• 生成动态库

SharedLibrary() buildsa shared library; a .so on Posix, a .dll in Win32

env= Environment()

env.SharedLibrary(target='foo',source=['l5.c', 'l6.c'])

env.SharedLibrary(target='bar',source=Split('l7.c l8.c'))

• 链接库

env= Environment(LIBS='mylib', LIBPATH=['.'])

env.Library(target='mylib',source=Split('l1.c l2.c'))

env.Program(target='prog',source=['p1.c', 'p2.c'])

• 分层构建

SConscript('lib/SConscript')

SConscript('test/SConscript')

# 构建实例

# SConstruct

env= Environment()

env.Program(target='foo',source='foo.c')

SConscript('sub/SConscript')

# sub/SConscript

env= Environment()

#Builds sub/foo from sub/foo.c

env.Program(target='foo',source='foo.c')

SConscript('dir/SConscript')

# sub/dir/SConscript:

env= Environment()

#Builds sub/dir/foo from sub/dir/foo.c

env.Program(target='foo',source='foo.c')
