Question

我试图在mac os x上使用SFML编译最小项目。我使用以下命令：

g++ -o rj -framework SFML -lsfml-graphics -lsfml-audio -lsfml-window -lsfml-system main.cpp

使用以下代码：

# include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow App(sf::VideoMode(800, 600, 32), "test");
    return 0;
}

并收到错误：

Undefined symbols for architecture x86_64:
  "sf::String::String(char const*, std::__1::locale const&)", referenced from:
  _main in main-15430b.o
ld: symbol(s) not found for architecture x86_64

我做错了什么？

Answer 1

我有同样的问题。我像在 tutorial中那样安装SFML，然后放入框架并确定了dylib。但是，当我想编译hello world程序时，我会遇到如下问题：

    undefined symbols for architecture x86_64:
  "sf::CircleShape::CircleShape(float, unsigned long)", referenced from:
      _main in main-1b3038.o
  "sf::RenderStates::Default", referenced from:
      _main in main-1b3038.o
  "sf::RenderTarget::draw(sf::Drawable const&, sf::RenderStates const&)", referenced from:
      _main in main-1b3038.o
  "sf::RenderTarget::clear(sf::Color const&)", referenced from:
      _main in main-1b3038.o
  "sf::RenderWindow::RenderWindow(sf::VideoMode, sf::String const&, unsigned int, sf::ContextSettings const&)", referenced from:
      _main in main-1b3038.o

...

当我这样做时：

clang++ main.cpp -I /usr/local/include

我的SFML库路径为：/usr/local/include/SFML

通过安装clang版本的库来解决问题。

在mac os x上使用SFML 2.1编译最小项目
