我尝试在anaconda安装（版本5）（使用虚拟环境）中使用带有distutils的boost库来构建扩展。该代码是James Gregson.
我的setup.py是
from distutils.core import setup, Extension
import sys, glob, os
# define the name of the extension to use
extension_name = 'ExtensionExample'
extension_version = '1.0'
libdir = r'C:\Users\schmmark\Anaconda3\envs\widy640\Library\lib'
# define the directories to search for include files
# to get this to work, you may need to include the path
# to your boost installation. Mine was in
# '/usr/local/include', hence the corresponding entry.
include_dirs = sys.path + [r'C:\Users\schmmark\Anaconda3\envs\widy640\Library\include', 'include',
r'C:\Users\schmmark\Anaconda3\envs\widy640\include']
# define the library directories to include any extra
# libraries that may be needed. The boost::python
# library for me was located in '/usr/local/lib'
library_dirs = [r'C:\Users\schmmark\Anaconda3\envs\widy640\Library\lib']
# define the libraries to link with the boost python library
libraries = ['boost_python37-vc140-mt-x64-1_67']
# define the source files for the extension
source_files = ['src/boost_python_wrapper.cpp', 'src/functions_to_wrap.cpp', 'src/classes_to_wrap.cpp']
# define link arguments
# I change this for testing
# extra_compile_args = ['-DBOOST_ALL_NO_LIB']
# extra_compile_args = ['- -DBOOST_ALL_DYN_LINK']
extra_compile_args = []
# create the extension and add it to the python distribution
setup(name=extension_name, version=extension_version, ext_modules=[
Extension(extension_name, source_files, include_dirs=include_dirs, library_dirs=library_dirs, libraries=libraries,
extra_compile_args=extra_compile_args)])
使用此配置，对于命令python setup.py build，我收到错误消息
LINK：致命错误LNK1104：无法打开文件'boost_pythonPY_MAJOR_VERSIONPY_MINOR_VERSION-vc140-mt-x64-1_67.lib'
即使文件夹boost_python37-vc140-mt-x64-1_67.lib中存在文件C:\Users\schmmark\Anaconda3\envs\widy640\Library\lib。
设置extra_compile_args = ['-DBOOST_ALL_NO_LIB']时错误消失，但是我不想手动导入所有标头。 msvc和boost有什么问题？
更新：
借助this answer，我在boost/python/detail/config.hpp行中进行了更改
#define BOOST_LIB_NAME boost_python##PY_MAJOR_VERSION##PY_MINOR_VERSION
到
#define BOOST_LIB_NAME boost_python37
但是我收到链接错误

答案 0 :(得分：0)
我发现了两个错误。
这似乎与使用的增强版有关。在撰写本文时，boost库是anaconda发行版中的1.67版。使用项目主页上的最新v1.69二进制文件时，错误消失了。从项目主页使用v1.67时，错误仍然存在。
在James Gregson中提到的示例cpp文件仍然为空。如果您编写实际的代码编译是可能的，例如为<?xml version="1.0" encoding="utf-8"?>
