当我尝试为 iphone 模拟器编译时出现以下错误。 我正在尝试使用没有提升的 websockets 和 cocos2d-x 我添加了这个库 Poco websockets

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
最佳答案
我对 POCO 了解不多，但看看您对 clang++ 的调用，我可以肯定地说您没有将任何 POCO 库链接到您的应用程序。
请务必为“-L”和“-l”选项指定正确的值(XCode 中必须有一种方法可以做到这一点)，一切都应该正常工作。
关于c++ - ld : symbol(s) not found for architecture i386 IOS c++，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/28987817/
