Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Building Engine - WaitMutex Exited with code 5

Hi All,

Any light on this topic would be much appreciated. I get the following error on a clean build of the engine:

C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.MakeFile.Targets(41,5): error MSB3075: The command "....\Build\BatchFiles\Build.bat UE4Editor Win64 Development -waitmutex" exited with code 5. Please verify that you have sufficient rights to run this command.

Thanks,

Product Version: UE 4.17

如果上面两个答案没用的话,试试我这个。

If those two answers are useless,Try mine.

这个问题我花了大半天时间来搜索解决方案。终于找到了有用的东西

I spent almost half day to search for the solution to this.Finally, I found something useful.

https://answers.unrealengine.com/questions/429455/link-errors-in-ubttasknode-classes.html https://answers.unrealengine.com/questions/511544/errorlnk2001-within-ubtservice-class.html?sort=oldest

可以参考一下上面两个问题的答案,其实两个都一样。

You can refer these two links above. Both the same, either one will be fine.

为了方便你们,我直接复制了解决方案:

For your convenient, I copyed it :

This is a known issue with changing to 4.12 and using tasks. It can be resolved by simply adding “GameplayTasks” to the PublicDependencyModuleNames section inside your ‘ProjectName’.Build.cs For example: PublicDependencyModuleNames.AddRange(new string[] { “Core”, “CoreUObject”, “Engine”, “InputCore”, “AIModule”, “GameplayTasks” });

在YourProjectName.Build.cs里的PublicDependencyModuleNames加上GameplayTasks就行。

Add GameplayTasks to PublicDependencyModuleNames of the YourProjectName.Build.cs file~.
