如何解決這個問題？ C++編譯器設置

我通過Xcode的安裝GCC，但我正在試圖編譯的文件時，這個錯誤：如何解決這個問題？ C++編譯器設置

如何解決這個問題？我很確定我的g ++編譯器已經正確設置，因爲它適用於不同文件夾中的文件。請幫助我解決這個問題..我是這個語言的初學者，我正在盡力理解。

包含Fraction類的模塊也必須編譯並鏈接到main.cpp以形成可執行文件。鏈接器正在搜索列出的符號 - 它們不在main.cpp中。 – suspectus 2013-04-27 10:29:25

您需要將包含Fraction類的cpp文件添加到命令行。像這樣的東西

g++ main.cpp Fraction.cpp

希望有幫助。 :)
