我从LibGDX和Java(最后!)转移到C ++和SDL。但是,在关注了许多设置视频和帖子后,我总是得到同样的错误:
Unknown type name SDL_Window
Unknown type name SDL_GLContext
非常感谢帮助。
#include <iostream>
#include <SDL2/SDL.h>
#ifdef __IPHONEOS__
# include <SDL2/SDL_opengles.h>
#else
#include <SDL2/SDL_opengl.h>
#endif
int width = 800;
int height = 600;
int main(int argc, char * argv[])
{
SDL_Init(SDL_INIT_VIDEO);
SDL_Window* window = SDL_CreateWindow("Test", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, width, height, SDL_WINDOW_OPENGL);
if(!window)
{
std::cerr << "Error failed to create window!\n";
return 1;
}
SDL_GLContext context = SDL_GL_CreateContext(window);
if(!context)
{
std::cerr << "Error failed to create a context\n!";
return 2;
}
SDL_Event event;
bool running = true;
glClearColor(1, 0, 0, 1);
while(running)
{
while(SDL_PollEvent(&event))
{
running = event.type != SDL_QUIT;
}
glClear(GL_COLOR_BUFFER_BIT);
SDL_GL_SwapWindow(window);
}
SDL_GL_DeleteContext(context);
SDL_DestroyWindow(window);
SDL_Quit();
return 0;
}
(这只是一个测试脚本,看它是否有效)

对我而言,这听起来像您已下载框架等并将其置于构建阶段,但可能您忘记更改其他标头和框架搜索路径的项目设置。
如果您想轻松入手,本教程有一个指向Xcode模板的链接,该模板可从Github下载,该模板将具有相关的项目设置。

检查您的构建设置。提到的模板(在另一个答案中)使用以下标题搜索路径:/usr/include /usr/local/include
我添加了第三个:/opt/local/include/SDL2
请注意,第三个来自MacPorts
