使用Boost.Python修复未解析的外部符号

Question

我正在尝试构建一个库并获得几个“未解决的外部符号”错误。我试图解决其中一个错误，这些错误应该让我知道如何继续。该错误是：未解析的外部符号IsProcessorFeaturePresent。根据我的理解，因为这不是我试图构建的代码的一部分，所以必须存在于“lib”文件中。根据this，lib文件应该是kernel32.lib。现在“Windows Kits”下有几个kernel32.lib文件。在Visual Studio Developer命令提示符中编译时，我认为默认情况下应该包括它，因为它应该是环境的一部分。我仍然添加了一个路径“C： Program Files （x86） Windows Kits 8.1 Lib winv6.3 um x64” 在图书馆JamFile的#requirements下我还添加了“ C： Program Files （x86） Windows Kits 8.1 包含 um“到它。但错误没有变化。如何找出它需要包含哪个文件？

注意：这个问题与如何解决未解决的外部符号错误不同，我已经完成了对该问题的回答，现在我正在尝试将其应用于此特定错误。

编辑：我正在尝试构建依赖于Boost.Python的libtorrent库。我在Boost的根目录中使用--with-python = C： Python27构建了Boost.Python。之后，我将BOOST_ROOT添加到环境变量中，并将其添加到路径中。之后我试图使用bjam variant=release memory-model=64构建libtorrent python绑定完整的错误日志是here.

编辑2：继续对这个问题的评论我已经将所需的库添加到JamFile，错误数量从187减少到11.剩下的错误是：

在qazxsw poi检查qazxsw poi（使用qazxsw poi）我检查了dumpbin的输出中是否存在所有符号，例如搜索libboost_python-vc141-mt-1_65_1.lib我得到这一行：

C:oost_1_65_1stagelib

我在我的JamFile中包含了这个lib文件。我还缺少什么？我在构建dumpbin /EXPORTS时是否需要通过一些选项我正在使用identity_function构建它
