缺少MediaLibsDemo的体系结构x86_64

Question

我使用以下库连接到Red5服务器。 https://github.com/slavavdovichenko/MediaLibDemos。 它给了我以下错误。如何将缺少的体系结构添加到以下文件中？或其他一些解决方案？

on implementing it, I am getting the following error.

看起来您使用的库不是为64位架构而构建的。如果情况确实如此，那么您需要将Xcode配置为仅构建32位（假设您无法获得64位版本）：

1. 在目标构建设置中指定有效体系结构以排除64位（arm64）
2. 将Build Active Architecture Only设置为NO（调试时）



默认情况下，在调试时，Xcode只会构建活动架构。因此，这意味着如果您在64位设备或模拟器上进行测试，Xcode将尝试构建64位二进制文​​件，这将与您的32位库不兼容。
