MediaLibsDemo缺少體系結構x86_64

Question

我正在使用以下庫連接到Red5服務器。 https://github.com/slavavdovichenko/MediaLibDemos。 它給我以下錯誤。我如何將缺少的體系結構添加到以下文件中？或其他解決方案？

on implementing it, I am getting the following error.

看起來您正在使用的庫不是爲64位體系結構而構建的。如果確實是這樣，你需要配置的Xcode僅建立32位（假設你不能得到一個64位版本）：

1. 指定目標構建設置，以排除有效的架構64位（arm64）
2. 集Build Active Architecture Only到NO（調試時）

默認情況下，當調試時，Xcode將只建立所述活性體系結構。所以這意味着如果您在64位設備或模擬器上進行測試，Xcode將嘗試構建一個64位二進制文​​件，這與您的32位庫不兼容。
