VS LINK无法打开文件'boost_python ...'而不是libboost_python3-vc140-mt-gd-1_65 [英] VS LINK cannot open file 'boost_python...' instead of libboost_python3-vc140-mt-gd-1_65

问题描述

今天早上，我安装了Python 3.6，安装了b2配置来编译boost lib，并且lib路径中都包含libboost_python3...两种风格.然后简单:

This morning I installed Python 3.6, got my b2 config to compile the boost lib and do have both flavors of libboost_python3... in the lib path. Then with a simple:

#include "stdafx.h"
#include <boost/python.hpp>

char const* greet()
{
    return "hello, world";
}

BOOST_PYTHON_MODULE(hello_ext)
{
    using namespace boost::python;
    def("greet", greet);
}

我收到链接器错误:

LINK : fatal error LNK1104: cannot open file 'boost_python-vc140-mt-gd-1_63.lib'

我已经搜索了像USING_BOOST_PYTHON3这样的标志，但是我读到的每件事都说它应该是自动的.根据我的构建，Boost应该包含适当的库.

I've searched for the likes of a flag like USING_BOOST_PYTHON3 but every thing I read says that it should be automatic. That Boost should include the proper lib according to what I've built.

此家伙遇到了同样的问题，但是没有得到答案.这与我在右边的类似问题"中的链接所能获得的接近.但是我看不到VS是其中的一部分，因为boost会选择libs.

This guy Had the same problem but never got an answer. That was as close as I could get to the links in 'Similar Questions' on the right. But I can't see how VS is part of this as boost will pick the libs.

更新:我刚刚找到:

#if PY_MAJOR_VERSION == 2
#  define BOOST_LIB_NAME boost_python
#elif PY_MAJOR_VERSION == 3
#  define BOOST_LIB_NAME boost_python3
#endif

所以现在看来​​，为什么我的主要版本是2而不是3?即使我:

So now it looks like why is my major version 2 instead of 3? And even if I:

#define PY_MAJOR_VERSION 3

在我的stdafx.h顶部，它仍然与python 2 lib链接. ！?

Right at the top of my stdafx.h it still links with the python 2 lib. !?

又一次更新: 这么早，我还没有安装python 2.7，我已经将其他库"设置为C:\cpp\Python27\libs，我只是将其设置为C:\cpp\Python36_3\libs，现在我得到了:

Yet Another Update: So early on, and I don't have python 2.7 'installed', I had set the Additional Libraries to C:\cpp\Python27\libs I just set it to C:\cpp\Python36_3\libs and now I get:

LINK : fatal error LNK1104: cannot open file 'python27.lib'

感觉很有意义，因为boost正在尝试链接到2.x而不是3.x

Makes sense as boost is trying to link to 2.x instead of 3.x

推荐答案

#define BOOST_PYTHON_STATIC_LIB 

链接:libboost_python3-vc140-mt-s-1_65_1.lib

link: libboost_python3-vc140-mt-s-1_65_1.lib
