不真实的引擎4.20插件中的构建错误：[自适应统一构建]禁用排除文件的PCH

Question

在更新到虚幻4.20之后，我试图构建一个项目时，插件的代码中出现了以下错误：

1>[Adaptive unity build] Disabling PCH for excluded files. Set bAdaptiveUnityDisablesPCH to false in BuildConfiguration.xml to change this behavior. 
1>[Adaptive unity build] Excluded from MyUnrealPlugin unity file: MyFile.cpp

作为一个实验，我按照错误消息的建议禁用了bAdaptiveUnityDisablesPCH，但是这样做只是将上面的错误替换为：

<>c.<PrintExceptionInfo>b__4_1: ==============================================================================
<>c.<PrintExceptionInfo>b__4_0: UnrealBuildTool: ERROR: UBT ERROR: Failed to produce item: E:\GameDirectory\UE4\MyGame\Plugins\MyPlugin\Intermediate\Build\Win64\UE4Editor\Development\MyPlugin\UE4Editor-MyPlugin.lib
<>c.<PrintExceptionInfo>b__4_0:                         (see ../Programs/UnrealBuildTool/Log.txt for full exception trace)

<>c.<PrintExceptionInfo>b__4_1: ==============================================================================

对我该做些什么来纠正这个问题有什么想法吗？

非常感谢！

Answer 1

结果是一个红鱼--实际的错误在构建输出中进一步上升，并且源于Windows10SDK中的一个错误，该错误以前在Win8 SDK中被视为警告。在这种情况下，这些错误对我们没有意义，因此禁用这些错误纠正了问题。

#pragma warning(disable:4668)   // x  is not defined as a preprocessor macro, replacing with '0' for '#if/#elif'
#pragma warning(disable:4005)   // 'TEXT': macro redefinition

我自己搜索，我发现"[Adaptive unity build] Excluded from XXX unity file:“后面列出的文件是cpp文件，根据git进行修改。

不太确定这是否解决了你的问题，但它帮助我停止追逐这条信息。
