LNK1120在構建Python包時引用Boost

我試圖使用Boost.Python將Python集成到我的C++程序中。我已經能夠編譯一些模塊了，但是這個一直給我提供鏈接器錯誤，抱怨boost-system未解決的外部錯誤。LNK1120在構建Python包時引用Boost

我有以下模塊：

BOOST_PYTHON_MODULE(platform) 
{ 
    boost::python::class_<mandala::platform_win32_t, boost::noncopyable>("platform", boost::python::no_init) 
     .def("get_window_title", &mandala::platform_win32_t::get_window_title); 
}

而下面setup.py腳本：

from distutils.core import setup 
from distutils.extension import Extension 

setup(name='mandala', 
    ext_modules=[ 
     Extension('platform', 
      ['../mandala/platform_win32.cpp'], 
     include_dirs=['C:\\boost_1_55_0', 
     '..\ext\glm-0.9.4.4', 
     '..\ext\glew-1.10.0\include', 
     '..\ext\glfw-3.0.1.bin.WIN32\include'], 
     library_dirs=['C:\\boost_1_55_0\stage\lib', 
     '..\ext\glfw-3.0.1.bin.WIN32\lib-msvc110', 
     '..\ext\glew-1.10.0\lib\Release\Win32'], 
     libraries=['glfw3', 'glew32', 'opengl32', 'user32', 'gdi32'] 
     ) 
    ])

惠蔭運行它，我得到下面的輸出。

我試圖把各種boost-system庫在setup.py腳本libraries陣中，但無濟於事。

任何幫助，將不勝感激！

編輯的platform_win32.cpp整體here。

你能否提供'mandala :: platform_win32_t :: get_window_title'函數的簽名？ – kvorobiev

@kvorobiev'platform_t :: window_title_type platform_win32_t :: get_window_title（）const的 \t { \t \t // TODO：實現這個 \t \t回報的std :: string（）; \t}'：P –

嗯..你可以添加到你的問題整個'platform_win32_t'代碼？ – kvorobiev

編譯錯誤通過將extra_compile_args=['/EHsc']添加到setup.py腳本來解決。
