我应该如何让 Xcode 链接使用 C++ 静态库的 iOS 项目 [英] How should I get Xcode to link an iOS project that uses a C++ static library

问题描述

使用 Xcode，我编写了一个 Cocoa Touch 静态库，主要是用 C++ 编写的.它为了 Objective-C 客户端代码公开了一个 C 接口.

Using Xcode, I've written a Cocoa Touch static library, mainly in C++. It exposes a C interface for the benefit of Objective-C client code.

我有一个使用它的客户端 iOS 应用程序，一切正常运行，除了我发现我需要在客户端项目中包含一个最小的 .cpp 文件以获取到成功.否则我会得到与 C++ 相关的未解析符号，例如operator new(unsigned long).

I have a client iOS app that uses it, and everything works and runs as expected, except that I found I needed to include a minimal .cpp file in the client project to get the link to succeed. Otherwise I get C++-related unresolved symbols, e.g. operator new(unsigned long).

上述 hack 既简单又有效，所以我想我没有违反任何法律，但是有没有合适的方法来消除我的链接器错误?

The above hack is easy and effective, and so I guess I'm not breaking any laws, but is there a proper way to eliminate my linker errors?

推荐答案

应该只是将 -lc++ 添加到项目设置中的链接器标志的问题，我想.

Should be just a matter of adding -lc++ to the linker flags in the project settings, I'd have thought.

在项目设置的构建设置"选项卡的链接"部分下的其他链接器标志"下添加它.

Add it under "Other Linker Flags" under "Linking" section of the "Build Settings" tab on your project's settings.
