虽然不直接是一个明确的问题 - 我正在尝试撰写一篇文章，解决在尝试安装boost-python作为新手时遇到的一些奇怪问题
该帖子基于this example，可直接通过
获取wget https://dl.dropboxusercontent.com/u/508241/wordpress/BoostPythonHelloWorld.tar.gz
tar xf BoostPythonHelloWorld.tar.gz
cd BoostPythonHelloWorld
cmake .
make
./test.py
一个大胆但准确的说法是，我已经系统地阅读了{em>所有相关的"boost-python hello world Makefile"（没有那么多）谷歌搜索结果，并通过每个SO帖子出现在搜索boost-python hello world Makefile。我尝试过的方法显然相当详尽，我也尝试过大量的例子。
我在Makefile的最佳成功是在这篇文章的最后以便于阅读。这些问题主要基于此。
brew install boost-python将在/usr/Cellar/boost/1.61.0/之类的地方安装提升，这可能导致大多数在线资源失败，除非明确链接Mac OS X附带原生python。大多数用户都会安装homebrew install python，这会导致cmake错误地链接到本机python。python库libpython2.7.dylib 以下Makefile的某些组合实际编译为100%但后来我有以下内容，似乎来自boost-python无法链接到{{ 1}}：
cpython我更改了我的 [ 25%] Building CXX object CMakeFiles/greet.dir/greet.cpp.o
[ 50%] Linking CXX shared library libgreet.dylib

[100%] Linking CXX shared library greet_ext.dylib

而没有清理我的Makefile几次，当我意识到我忘记清除旧文件时，我已经更改了Build/太多来重新创建这个成功的程度
Makefile编译时没有错误，但我无法导入，因为我应该可以使用SHARED import greet_ext Makefileproject( BoostPythonHelloWorld )

输出使用命令：Makefile在我获得的目录rm -rf Build; mkdir Build; cd Build; cmake ..; make;中：
BoostPythonHelloWorld答案 0 :(得分：1)
这并没有直接解决CMAKE finds wrong dirs of Boost (Mac OSX default)...
... Include Include of boost: /usr/local/include
... Actual Include of boost: /usr/Cellar/boost/1.61.0/include}
-- Found PythonLibs: /usr/lib/libpython2.7.dylib (found suitable version "2.7.10", minimum required is "2.7")
CMAKE finds wrong dirs of Python (Mac OSX default)...

问题，而是让其他python用户意识到我的突破，Makefile没有必要。
我仍会接受任何导致Makefile尝试修复的答案。
使用其他示例Makefile：
hello_ext.cpp我可以使用从this post获取的char const* greet()
{
return "hello, world";
}
#include <boost/python.hpp>
BOOST_PYTHON_MODULE(hello_ext)
{
using namespace boost::python;
def("greet", greet);
}
将其导入到python中：
setup.py建立：from distutils.core import setup
from distutils.extension import Extension
hello_ext = Extension(
'hello_ext'
,sources=['hello_ext.cpp']
,libraries=['boost_python-mt'] # for python 3 use 'boost_python3-mt'
# you may also want to add these
,extra_compile_args=['-std=c++11','-stdlib=libc++']
,extra_link_args=['-stdlib=libc++']
)
setup(
name='hello-world',
version='0.1',
ext_modules=[hello_ext])
我能够成功导入！
python setup.py build_ext --inplace作为旁注：以下内容属于In [1]: ls
Makefile build/ hello_ext.cpp hello_ext.so* setup.py
import hello_ext
hello_ext.greet()
