Question

我开发了一个相当大的应用程序，在我的Mac上使用Xcode（5.1.1）。所有代码都运行完美，并按照它的设想行事。但是，当我在我的大学linux服务器上重新编译相同的代码时，gcc 4.8.3会显示无数错误。使用pscp命令将源代码文件上载到服务器，因此不涉及任何形式的修改。我的问题是：有没有办法做一个＆＃34;兼容模式＆＃34;在Xcode上，以便我可以在上传到大学服务器之前尝试解决任何兼容性问题？

编辑：有些错误是：

实际上，我要将我的评论扩展为答案。

评论：看起来GCC没有构建为C ++ 11，而Xcode（可能是LLVM）。例如。请参阅声明nullptr未定义。

要强制LLVM进行编译，就好像Xcode中的旧式C ++编译器一样，打开项目设置，导航到这个：

...并选择C ++ 98。

在XCode和Linux上进行交叉编译？
