Question

我构建了boost python（1.55），没有任何错误或警告。这是清单：

C:\Programming\boost>b2 toolset=msvc-11.0 link=static variant=release threading=multi runtime-link=static --with-python
link.jam: No such file or directory
Building the Boost C++ Libraries.

The Boost C++ Libraries were successfully built!
The following directory should be added to compiler include paths:
    C:/Programming/boost
The following directory should be added to linker library paths:
    C:\Programming\boost\stage\lib
C:\Programming\boost>

编辑：

但如果我将它添加到我的项目中（参考文献 - ＆gt;链接器 - ＆gt;输入 - ＆gt;其他依赖项），我会收到链接器错误，例如：

PyRunnable.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) class boost::python::api::object __cdecl boost::python::api::getitem(class boost::python::api::object const &,class boost::python::api::object const &)" (__imp_?getitem@api@python@boost@@YA?AVobject@123@ABV4123@0@Z)
PyRunnable.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) class boost::python::api::object __cdecl boost::python::api::getattr(class boost::python::api::object const &,char const *)" (__imp_?getattr@api@python@boost@@YA?AVobject@123@ABV4123@PBD@Z)
PyRunnable.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) protected: __thiscall boost::python::detail::str_base::str_base(void)" (__imp_??0str_base@detail@python@boost@@IAE@XZ)

如果我使用dumpbin / symbols，我甚至可以找到未解决的方法。所以，他们在里面，但VS2012以某种方式忽略了它们。为什么？

在Additional dependencies字段中有：

libboost_system-vc110-mt-1_55.lib
libboost_program_options-vc110-mt-1_55.lib
libboost_filesystem-vc110-mt-1_55.lib

并没有问题。但是如果我在那里添加libboost_python-vc120-mt-1_55.lib，我仍然会得到15个链接器错误。我做错了什么？

提前谢谢。

这是正常的。 dumpbin /exports选项用于显示从PE文件（例如DLL）导出的函数，而不是用于列出COFF库中的函数。

要列出COFF库中的函数，请使用/symbols选项：

dumpbin /symbols libboost_python-vc110-mt-s-1_55.lib

为什么在没有任何导出功能的情况下增强python构建
