在XCode和Linux上交叉編譯？

Question

我使用Xcode（5.1.1）在Mac上開發了一個相當大的應用程序。 所有代碼都可以完美運行，並且可以執行預期的操作。 但是，當我在具有gcc 4.8.3的大學linux服務器上重新編譯相同的代碼時，會出現無數的錯誤。 使用pscp命令將源代碼文件上載到服務器，因此不涉及任何形式的修改。 我的問題是：是否可以在Xcode上執行“兼容模式”，以便在上載到University服務器之前嘗試解決所有兼容性問題？

編輯：一些錯誤是：

Answer 1

實際上，我將把我的評論擴展為答案。

評論：看起來GCC並沒有像C ++ 11那樣構建，而Xcode（LLVM，大概是）構建了。 例如，查看有關nullptr未定義的說法。

要強制LLVM像Xcode中的老式C ++編譯器一樣進行編譯，請打開您的項目設置，導航至以下設置：

...，然后選擇C ++ 98。
