在 Xcode 10 中找不到架构 x86_64 的符号（错误）答案

【问题标题】：symbol(s) not found for architecture x86_64 in Xcode 10 (ERROR)在 Xcode 10 中找不到架构 x86_64 的符号（错误）
【发布时间】：2022-05-05 18:41:23
【问题描述】：

我在我的 ios 项目中遇到了这个问题。 Xcode clang 中未找到架构 x86_64 的符号：错误：链接器命令失败，退出代码为 1（使用 -v 查看调用）。我多次尝试解决我的 xcode 和项目文件夹。我被困住了。有任何想法吗？日志如下。我正在尝试在 Xcode 10 上运行模拟器构建。

【问题讨论】：

您好像不见了glog？
这可能是一切，但我知道这通常发生在您尝试运行具有仅与真实设备（无模拟器）兼容的框架的项目时...
我在一个项目中遇到了同样的问题，glog 是项目中的一个 pod，链接器似乎找不到它？

标签： ios xcode

【解决方案1】：

在 pod 内部，在目标下，然后单击 React，然后构建阶段 > 将 Binary 与库链接，添加 DoubleConversion.Framework 和 glog.framework 和 Folly.framework。每当您进行 pod 更新时，请确保将它们添加到 react 依赖项下，然后运行。

【讨论】：

【解决方案2】：

在 React.podspec 你需要改变

ss.compiler_flags       = folly_compiler_flags

到

ss.dependency             "DoubleConversion"
ss.dependency             "GLog"
ss.compiler_flags       = folly_compiler_flags

3 部分

ps：GLog 或 glog

【讨论】：

【解决方案3】：

我在 2 月 12 日也面临同样的问题。所以我在Github 上针对这个问题打开了一个问题。

有解决此问题的方法。

在@CocoaPods 项目中手动添加 DoubleConversion 和 glog 到 Link Binary With Libraries of React 框架目标。

这个问题在 RN 0.58.4 中修复

【讨论】：

【解决方案4】：

当我阅读错误消息时，解决方案非常简单......

只需将 x86_64 架构添加到您的依赖项即可。我还没有，因为我将 React-Native 添加到现有的 ios 应用程序中，它与应用程序有一些差异，应用程序默认使用 React-Native 创建。 React-logger -> Build Settings -> Architectures
