Question

我正在尝试使用Boost.Python将Python集成到我的C ++程序中。我已经能够很好地编译一些模块，但是这个模块始终给我链接器错误抱怨来自boost-system的未解析的外部。

我有以下模块：

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);
}

以下setup.py脚本：

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']
        )
    ])

运行它，我得到以下输出。

我试图在boost-system脚本中的libraries数组中放置各种setup.py库，但无济于事。

任何帮助将不胜感激！

修改 platform_win32.cpp的整数为here。

通过将extra_compile_args=['/EHsc']添加到setup.py脚本来修复编译错误。
