Question

我希望使用boost-python3用xcode将我的C ++代码包装在macos中。我想使用xcode，因为它已链接到JUCE音乐包。我使用了一个来自Boost教程的简单示例：

#include <boost/python.hpp>

char const* greet()
{
    return "hello, world";
}

BOOST_PYTHON_MODULE(hello_ext)
{
    using namespace boost::python;
    def("greet", greet);
}

当我编译代码时，出现链接问题。

我查看了现有的文档和问题，并更改了包含路径和库路径。目前，我使用了这些：

标题搜索路径：

/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/include/python3.7m/

图书馆搜索路径：

/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/

这是链接日志：

和我得到的错误：

Undefined symbols for architecture x86_64:

boost::python::to_python_value<char const* const&>::get_pytype() 
const in Source.o
"__Py_NoneStruct", referenced from:

谢谢！

使用macOS将boost-python3与xcode链接时出现问题
