如何解决这个问题？ C++编译器设置

我通过Xcode的安装GCC，但我正在试图编译的文件时，这个错误：如何解决这个问题？ C++编译器设置

如何解决这个问题？我很确定我的g ++编译器已经正确设置，因为它适用于不同文件夹中的文件。请帮助我解决这个问题..我是这个语言的初学者，我正在尽力理解。

包含Fraction类的模块也必须编译并链接到main.cpp以形成可执行文件。链接器正在搜索列出的符号 - 它们不在main.cpp中。 – suspectus 2013-04-27 10:29:25

您需要将包含Fraction类的cpp文件添加到命令行。像这样的东西

g++ main.cpp Fraction.cpp

希望有帮助。 :)
