Question

我有一个非常古老的遗产项目（从2010年开始约会）。它的Crashlytics工具包最后一次更新于2013年。

我试图更新它。它不使用pod，因此我使用了official Manual update指南。

我下载了更新的工具包。
按照建议用新的替换旧的Crashlytics。旧的没有Fabric工具包，所以我只是将其粘贴在那里并在Project设置中链接了库。

这是这里描述的唯一两个步骤。但这样做会导致链接器错误：

我尝试过的事情：

删除Crashlytics和Fabrics的引用并重新链接它们。
删除两个工具包的物理实例并读取它们。
清理XCode的派生数据。
清洁项目。
通过Cocoapods安装最新版本。
通过Fabric App升级

但错误仍然存在。现在，我在我的智慧结束。关于如何解决这个问题的任何想法？

Answer 1

我明白了。

问题是，前一个人修改了链接器和编译器标志，并从它们中移除了$(inherited)标志，这标志覆盖了Cocoapods配置，这反过来导致主项目与Cocoapods链接失败，因此缺少符号XCode无法找到没有链接的符号。

首先，我删除了Crashlytics手册，然后通过cocoapods安装它们。现在它说符号丢失了。

解决此问题：

转到＆＃34;预处理器宏＆＃34;并确保将$(inherited)添加到调试和释放配置中。
转到＆＃34;其他链接标记＆＃34;并确保在那里添加$(inherited)标志。

Crashlytics 3.8.4现已启动并运行。

Crashlytics手册更新到3.8.4导致链接器错误
