Question

我尝试使用boost-python在C ++上进行python绑定，但我无法编译，我无法找到原因。

我正在使用来自boost-python hello.cpp的代码示例：

#include <boost/python/class.hpp>
#include <boost/python/module.hpp>
#include <boost/python/def.hpp>
#include <iostream>
#include <string>

namespace { // Avoid cluttering the global namespace.

  // A friendly class.
  class hello
  {
    public:
      hello(const std::string& country) { this->country = country; }
      std::string greet() const { return "Hello from " + country; }
    private:
      std::string country;
  };

  // A function taking a hello object as an argument.
  std::string invite(const hello& w) {
    return w.greet() + "! Please come soon!";
  }
}

BOOST_PYTHON_MODULE(extending)
{
    using namespace boost::python;
    class_<hello>("hello", init<std::string>())
        // Add a regular member function.
        .def("greet", &hello::greet)
        // Add invite() as a member of hello!
        .def("invite", invite)
        ;

    // Also add invite() as a regular function to the module.
    def("invite", invite);
}

使用此Jamroot：

exe hello : hello.cpp ;

当我运行b2 --debug-configuration -n时，一切似乎都很好：

但是当我运行b2来编译我的绑定时，他找不到python头文件：

我已经使用Homebrew安装了boost和boost-build。

有什么想法吗？

它可能与您使用自制软件python有关，但Boost链接到系统Python。

无法在OS X上使用boost-python编译python绑定
