缺少MediaLibsDemo的體系結構x86_64

Question

我使用以下庫連接到Red5服務器。 https://github.com/slavavdovichenko/MediaLibDemos 。 它給了我以下錯誤。 如何將缺少的體系結構添加到以下文件中？ 或其他一些解決方案？

on implementing it, I am getting the following error.

看起來您正在使用的庫不是為64位架構而構建的。 如果確實如此，則需要將Xcode配置為僅構建32位（假設您無法獲得64位版本）：

1. 在目標構建設置中指定有效的體系結構以排除64位（arm64）
2. Build Active Architecture Only將Build Active Architecture Only設置為NO （調試時）

默認情況下，在調試時，Xcode只會構建活動架構。 因此，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64位二進制文​​件，這將與您的32位庫不兼容。
