MediaLibsDemo缺少体系结构x86_64

Question

我正在使用以下库连接到Red5服务器。 https://github.com/slavavdovichenko/MediaLibDemos。 它给我以下错误。我如何将缺少的体系结构添加到以下文件中？或其他解决方案？

on implementing it, I am getting the following error.

看起来您正在使用的库不是为64位体系结构而构建的。如果确实是这样，你需要配置的Xcode仅建立32位（假设你不能得到一个64位版本）：

1. 指定目标构建设置，以排除有效的架构64位（arm64）
2. 集Build Active Architecture Only到NO（调试时）

默认情况下，当调试时，Xcode将只建立所述活性体系结构。所以这意味着如果您在64位设备或模拟器上进行测试，Xcode将尝试构建一个64位二进制文​​件，这与您的32位库不兼容。
