you may need to include the boost tool into waf to test this script.

def options(opt):
opt.load('compiler_cxx boost')
def configure(cfg):
cfg.load('compiler_cxx boost')
cfg.check_boost()
cfg.env.DEFINES_BOOST = ['NDEBUG']
### the following line would be very convenient
### cfg.env.USE_MYCONFIG = ['BOOST']
### but this works too:
def copy_config(cfg, name, new_name):
i = '_'+name
o = '_'+new_name
l = len(i)
d = {}
for key in cfg.env.keys():
if key[-l:] == i:
d[key.replace(i,o)] = cfg.env[key]
cfg.env.update(d)
copy_config(cfg, 'BOOST', 'MYCONFIG')
# now modify the new env/configuration
# this adds the appropriate "boost_" to the beginning
# of the library and the "-mt" to the end if needed
cfg.env.LIB_MYCONFIG = cfg.boost_get_libs('filesystem system')[-1]
def build(bld):
# basic boost (no libraries)
bld.program(target='test-boost2', source='test-boost.cpp',
use='BOOST')
# myconfig: boost with two libraries
bld.program(target='test-boost', source='test-boost.cpp',
use='MYCONFIG')
# warning:
# notice the NDEBUG shows up twice in the compilation
# because MYCONFIG already includes everything in BOOST
bld.program(target='test-boost3', source='test-boost.cpp',
use='BOOST MYCONFIG')
我想出来了,步骤如下:
在wscript文件的configure函数中添加了以下签入。这将告诉脚本检查给定的库文件(本例中为libmongoclient),并将此检查的结果存储在MONGOCLIENT中。
在这一步之后,我们需要将包配置文件(.pc)添加到/usr/local/lib/pkgconfig路径中。这是我们指定lib和header路径的文件。正在粘贴下面此文件的内容。
将依赖项添加到sepcific程序的构建函数中,该函数依赖于上述库(即MongoClient)。下面是一个例子。
在此之后,再次运行配置,并生成代码。
我找到了答案。您只需将“INCLUDES”的值设置为所需的路径列表。 不要忘记再次运行
waf configure
:)我花了一些时间在bld.program()方法中使用“use”选项来找到一个很好的方法。以boost库为例,我提出了以下几点。希望有帮助!
