Question

我正在尝试使用VS2017在Windows上构建Boost 1.64。一切都构建没有错误，但我的输出libs目录缺少一些.lib和.dll s。具体来说，我需要的主要缺失库是Boost.Python。

我最近的建筑尝试看起来像这样，虽然我尝试了很多不同的选项组合：

.\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

我的构建输出如下所示：

...found 1 target...

注意事项：

我使用Miniconda而不是传统的Python安装。可能是个问题，虽然--debug-configuration的输出肯定表明它正在找到所有内容。
添加一些调试消息后，我发现它找到的1 target是all目标;我没有看到boost.python源的任何类型的构建输出，就像我看到我是否构建其他库一样。
添加额外的调试输出并不是特别有用;即使有最大的调试输出，我也无法找到任何与Python相关的错误或警告。
我也尝试从boost.python quickstart开始，它成功编译但无法链接，因为找不到boost_python.dll。（虽然从技术上讲，我认为它应该寻找像boost_python-vc141-mt-1_64.dll ...）

我为bootstrap.bat（例如--with-libraries=python，--with-python=C:\Miniconda2\python.exe，--with-python-root=C:\Miniconda2）和b2.exe尝试了多种选项组合，但似乎没有任何结果差异。

如果我下载预编译的boost_python库并将它们与我构建的其余库放在一起，我的项目将按预期构建和运行。自己构建python库是我唯一坚持的事情。

我知道我并不孤单;我在Reddit thread发布了这个问题，另一个用户提到他有同样的问题;不幸的是，他的解决方案是＆＃34;最终选择了bootstrap和b2＆＃34;的正确选项。

有没有其他人遇到这样的问题？

Answer 1

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

最初，我有这样的配置：

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

documentation似乎表明离开＆＃34;版本＆＃34;空的很好;我认为一个空版本应该意味着＆＃34;默认版本＆＃34;或＆＃34;所有版本＆＃34;。然而，这导致了无声地跳过构建python库的推动。

在明确指定Python版本时，所有内容都按预期构建：

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

Answer 2

使用Visual Studio构建python boost 1.64 libs似乎是broken。

将<boost_root>/‪libs/python/build/Jamfile替换为this。

我正在构建它this way：

wget.exe https://dl.dropboxusercontent.com/u/59547297/Libraries/boost_1_64_0.zip -OC:\thirdparty\vs2015\x64\boost_1_64_0.zip    
7za.exe x C:\thirdparty\vs2015\x64\boost_1_64_0.zip -oC:\thirdparty\vs2015\x64
xcopy /y boost_1_64_0\Jamfile C:\thirdparty\vs2015\x64\boost_1_64_0\libs\python\build\Jamfile
del C:\thirdparty\vs2015\x64\boost_1_64_0.zip
call "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" amd64
