链接器命令失败，退出代码 1、XCode 4.5、Facebook SDK 3.1

Posted 2023-02-24

【中文标题】链接器命令失败，退出代码 1、XCode 4.5、Facebook SDK 3.1

【英文标题】：Linker command failed with exit code 1, XCode 4.5, Facebook SDK 3.1

【发布时间】：2012-10-27 01:07:07

【问题描述】：

我正在尝试将 Facebook SDK 集成到我的 xcode 项目中，但我遇到了一个绊脚石。

经过一些研究，我尝试确保我拥有最新版本的 FacebookSDK，因为那些与我有相同错误的人能够使用最新版本解决他们的问题，但这并没有帮助，所以我尝试下载来自github的源代码并使用build_all.sh命令重新编译，这也没有帮助。

我会把完整的错误日志放在最后，因为它超长，但这是最后的部分：

clang：错误：链接器命令失败，退出代码为 1（使用 -v 查看调用）

我已经看到很多与此问题相关的字符串，但正如我之前所说，既没有更新到最新的 SDK（在我的情况下这是不必要的步骤，因为我已经有了它）或重新编译 armv7 的源代码，armv7s 修复了问题。

提前致谢，

汤姆

【参考方案1】：

您缺少社交网络框架，请将其添加到目标中构建阶段二进制库的链接中。

【讨论】：

我从未听说过由于缺少另一个框架的链接而导致的错误“重复符号”。
