我使用正确的Python配置,使用b2编译了boost 1.50.0库。以下是b2 --debug-configuration
命令的相关输出:

我已经正确设置了链接器目录,并链接到相应的输出文件(发布版本使用
libboost_python3-vc100-mt-1_50.lib
,调试版本使用libboost_python3-vc100-mt-gd-1_50.lib
)。我正在使用自编译的Python分发版,但我也尝试过标准版,结果并没有任何不同。当我编译时出现以下链接错误:
error LNK2019: unresolved external symbol "__declspec(dllimport) protected: __thiscall boost::python::detail::str_base::str_base(char const *)" (__imp_??0str_base@detail@python@boost@@IAE@PBD@Z) referenced in function "public: __thiscall boost::python::str::str(char const *)" (??0str@python@boost@@QAE@PBD@Z)

fatal error LNK1120: 3 unresolved externals
产生这些错误的测试代码如下所示:
using namespace boost::python;
object main_module = import("__main__");
我使用了相同的构建配置并且没有遇到任何问题,同时也使用了Boost.Filesystem库。希望有人能够帮我解决这个问题,因为它让我感到非常困惑!更新:我刚刚阅读了一些关于宏定义 BOOST_PYTHON_STATIC_LIB 的模糊文字;我不确定我是否在正确的方向上解决了这个问题(因为在构建过程中好像没有提到),但无论如何,它给我带来了更加混乱的错误。
LINK : fatal error LNK1104: cannot open file 'python27.lib'
我不知道为什么它试图链接那个库,因为python-cfg输出清楚地显示它已经找到了我的python33分发包(我的应用程序已经链接了python33.lib)。
