【问题描述】：
我正在尝试编译我的第一个 SDL 程序，但它无法编译。顺便说一句，我猜这不应该是关于设置库，因为我认为我正确安装了库。
这是我的命令：
g++ main.cpp -o main -I/Library/Frameworks/SDL2.framework/Headers -framework SDL2
这是我的代码：
#include <iostream>
#include <SDL.h>
int main(int argc, char **argv){
if (SDL_Init(SDL_INIT_EVERYTHING) != 0){
std::cout << "SDL_Init Error: " << SDL_GetError() << std::endl;
return 1;
}
SDL_Quit();
return 0;
}
这是错误信息：
clang: error: linker command failed with exit code 1 (use -v to see invocation)

ld: framework not found SDL2
我做错了什么？感谢您的帮助:)
【问题讨论】：
-
应该
.是标题路径中的``？ -
我更新了。您如何看待这个问题？
-
您是否尝试过使用
-v to see invocation？ -
framework not found SDL2，您没有链接 SDL 库。 -
我认为是
g++ (your other stuff here) -l<Library Name>。在您的情况下，我假设您的库名称是SDL。您应该在某处为 SDL 提供.lib，尝试使用它的名称。
