Windows Boost 1.64 VS2017 missing Python libraries

本文关键字：missing Python libraries VS2017 Boost Windows 更新时间：2023-10-16

我试图用VS2017在Windows上构建Boost 1.64。一切都没有错误构建，但是我的输出libs目录缺少某些.lib和.dll s。具体来说，我需要的主要缺少库是boost.python。

我最近在建造的尝试看起来像这样，尽管我尝试了许多不同的选项组合：

.b2 --prefix=c:boost --build-dir=boost_build --layout=versioned toolset=msvc-14.1 address-model=64 -j4 --with-python -a --reconfigure --stage-dir=stage --build-type=complete --debug-configuration -d2 stage >build.log 2>&1

，我的构建输出看起来像这样：

...found 1 target...

要注意的事情：

我使用Miniconda而不是传统的Python安装。可能是一个问题，尽管--debug-configuration的输出似乎表明它正确找到了所有内容。
添加了一些调试消息后，我发现它发现的1 target是all目标。我看不到boost.python来源的任何形式的构建输出，就像我看到是否构建了其他库。
添加额外的调试输出并不特别有用；即使有最大的调试输出，我也找不到与Python有关的任何错误或警告。
我还尝试从boost.python QuickStart开始，该QuickStart成功编译但无法链接，因为它找不到boost_python.dll。(尽管从技术上讲我认为应该寻找boost_python-vc141-mt-1_64.dll之类的东西...(

我尝试了bootstrap.bat(例如--with-libraries=python，--with-python=C:Miniconda2python.exe，--with-python-root=C:Miniconda2(和b2.exe的多种选项组合，但似乎没有任何区别。

如果我下载了预编译boost_python库，并将它们与我构建的其余库一起放置，则我的项目将按预期构建和运行。我自己构建Python库是我唯一仍然陷入困境的东西。

我知道我并不孤单。我用reddit线程发布了这个问题，另一个用户提到他也有同样的问题。不幸的是，他的解决方案是"最终击中Bootstrap和B2的正确选择"。

是否有人遇到过这样的问题？

我最终将其追溯到我的user-config.jam，我的Python版本未指定。

最初，我有此配置：

using python 
    : # version
    : C:\Miniconda2\python.exe
    : C:\Miniconda2\include
    : C:\Miniconda2\libs
    ;

该文档似乎表明"离开版本"是空的。我认为一个空版本应该是指"默认版本"或"所有版本"。但是，这导致Boost默默跳过构建Python库。

明确指定Python版本时，一切都按预期建立了：

using python 
    : 2.7                        # version
    : C:\Miniconda2\python.exe # interpreter
    : C:\Miniconda2\include    # include dir
    : C:\Miniconda2\libs       # library dir
    ;

构建python boost 1.64 libs with Visual Studio似乎被打破了。

替换<boost_root>/‪libs/python/build/Jamfile。

我是这样构建的：
