[英]Linker Errors on OS X due to SFML framework
这可能看起来像一个'noob'问题:我已经下载了适用于Mac的SFML-1.6,并且已将框架放入my / Library / Frameworks文件夹中。 在尝试编译示例SFML应用程序之后,我几乎每次调用SFML都会遇到链接器错误。 我不确定我错过了什么? 我对OSX和Frameworks没有太多经验,所以也许我需要通过其他方法链接到库?
输出,如果它有帮助:

您需要在链接器选项中添加两个标志:
-framework SFML
这告诉链接器使用/Library/Frameworks/SFML.framework
的框架
此外,您必须为您正在使用的每个库包含-lsfml-whatever
:
-lsfml-system
-lsfml-window
-lsfml-graphics
-lsfml-audio
-lsfml-network
因此,完整的链接器行可能如下所示:
g++ -framework SFML -lsfml-graphics -lsfml-audio -lsfml-window -lsfml-system
这在Mac OSX SFML构建文档中并不是很明显,但您确实需要这两者。
