sdl - 使用pybind11修改SDL程序

问题描述

我正在将我的 .cpp 代码修改为图形渲染器，但遇到了一个问题。这是我的代码：

PYBIND11_MODULE(mygameengine, m)
{
    py::class_<GraphicsEngineRenderer>(m, "GraphicsEngineRenderer")
        .def(py::init<int, int>(), py::arg("w"), py::arg("h"))
        .def("GetRenderer", &GraphicsEngineRenderer::GetRenderer, py::return_value_policy::reference);

}

而且错误太多，我只能展示其中的一部分

/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pybind11/include/pybind11/pybind11.h:1316:22: note:

         ^
  /Library/Frameworks/SDL2.framework/Headers/SDL_render.h:131:8: note: forward
  declaration of 'SDL_Renderer'

  struct SDL_Renderer;

函数的定义如下

  SDL_Renderer* GraphicsEngineRenderer::GetRenderer(){
      return m_renderer;
  }

我真的很想知道如何解决这个问题。我环顾四周，无法弄清楚。提前致谢。
