使用添加了extras / boost.py的waf 1.7.9,我发现你必须在配置时获取库,这使得构建具有不同库集的目标变得困难。例如,我有两个程序,一个只需要来自boost(程序'a')的头文件,另一个只需要一些库(程序'b')。这是我的解决方案,但我的问题是:有更好/首选的方法吗?
#! /usr/bin/env python
# encoding: utf-8
def options(opt):
opt.load('compiler_cxx boost')
def configure(conf):
conf.load('compiler_cxx boost')
conf.check_boost()
conf.env.DEFINES_BOOST = ['NDEBUG']
conf.env.LIB_BOOST_FILESYSTEM = conf.boost_get_libs('filesystem system')[-1]
conf.env.LIB_BOOST_PROGRAM_OPTIONS = conf.boost_get_libs('program_options')[-1]
def build(bld):
# program 'a' requires header-only part of boost
bld.program(
target = 'a',
source = 'a.cpp',
use = ['BOOST'] )
# program 'b' requires link to some boost libraries
bld.program(
target = 'b',
source = 'b.cpp',
use = ['BOOST', 'BOOST_FILESYSTEM', 'BOOST_PROGRAM_OPTIONS'] )

我不知道是否有一种首选方式,但我认为有一种方法可以减少它的魔力。基本上,不要使用额外的提升。没有它,您可以准确指定要包含的库。
#!/usr/bin/env python
# encoding: utf-8
def options(opt):
opt.load('compiler_cxx')
def configure(conf):
conf.load('compiler_cxx')
# NOTE: The uselib_store keyword argument is not necessary here, it is just added
# So that it is clear what name is required to use it during building.
conf.check(compiler='cxx',lib='boost_filesystem',uselib_store='BOOST_FILESYSTEM')
conf.check(compiler='cxx',lib='boost_program_options',uselib_store='BOOST_PROGRAM_OPTIONS')
# NOTE: I don't know what DEFINES_BOOST is used for
# conf.env.DEFINES_BOOST = ['NDEBUG']
# This will give you a command line define
conf.define('NDEBUG,'',quote=False)
def build(bld):
# NOTE: Specifying include directories is dependent on your platform. I think Waf
# takes care of this for you, but I'm putting it here for effect.
inc = ['/usr/include']
# program 'a' requires header-only part of boost
bld.program(
target = 'a',
source = 'a.cpp',
use = []
includes = inc )
# program 'b' requires link to some boost libraries
bld.program(
target = 'b',
source = 'b.cpp',
use = ['BOOST_FILESYSTEM', 'BOOST_PROGRAM_OPTIONS'],
includes = inc)
