Boost Python教程上运行bjam的链接器错误

Ora*_*bet 5 boost lnk2019 bjam boost-python lnk2001

我已经使用我能找到的每个boost python资源以及我能想到的每个安装和构建排列来解决这个问题已有40个小时了，但找不到对我有用的任何东西。

像我之前的许多人一样，当我在boost/boost_1_60_0/libs/python/example/tutorial目录中运行bjam时，出现链接器错误。我有Visual Studio 2015，并且尝试通过user-config.jam位于主目录中的文件的不同配置在32位Anaconda，64位Anaconda和纯Python 2.7上运行bjam 。

这是bjam使用任何设置运行后的构建日志。

您正在混合不同位数的库。构建 64 位 Boost Python 时，您必须链接到 64 位 Python，对于 32 位构建也是如此。

确保将两个版本的 Python 安装到不同的目录。我在安装程序中使用了默认目录，两个安装最终都在同一目录中。尽管我在安装 32 位版本之后安装了 64 位版本，但我的 Python libs/ 文件夹中仍然只有 32 位库。
