EarlGrey 2不会构建-未定义的符号

Question

由于EearGrey2的pod版本目前已经相当过时，我尝试使用直接复制的方法，并在构建AppFramework时有点卡住了。所以我遵循了这里的设置指南：Earlgrey 2 on Github

git clone -b earlgrey2 https://github.com/google/EarlGrey.git
cd EarlGrey
sh Scripts/download_deps.sh

然后我在XCode中打开EarlGrey.xcodeproj文件，开始构建所有的目标，除了ApppFramework之外的所有目标都构建得没有任何问题。但是当我尝试构建AppFramework目标时，首先我得到了一个关于在GreyAppStateTracker.m (第361行)中使用self的错误，我通过将_printAppStateTrackerLog更改为self->_printAppStateTrackerLog修复了这个错误。但在第二次构建尝试时，我得到了以下错误(如果我为arm或x86_64构建，这无关紧要，下面是我为arm64构建时的错误)，我无法修复：

我不太确定为什么它看不到这些符号。任何帮助都将不胜感激。我使用的是XCode 12.0以防万一。

Answer 1

我也有同样的问题。看一下这两个文件

公用库/配置/GREYAppState.m


CommonLib/GREYLogger.m

它们目前不是项目的一部分，但它们应该是项目的一部分。添加它们，并确保目标成员身份为for both设置为AppFramework。在那之后，AppFramework在我的系统上正确构建。
