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"

ERROR: UBT ERROR: Failed to produce item: UE4Editor-UPupilLabsVR.dll

Hey guys, I am new into UE. Iam trying to connect UE to the VR-Eye-Tracker from PupilLabs using zeroMQ.

I found this plugin https://github.com/SysOverdrive/UPupilLabsVR which I tried to build into the engine. With this command: .\RunUAT.bat BuildPlugin -plugin="C:\Users\VR\Documents\UnrealProjects\Plugins\UPupilLabsVR/UPupilLabsVR.uplugin" -package="C:\Users\VR\Documents\UnrealProjects\HelloWorld\PL_Packaged"

I always get this Error message: UnrealBuildTool: ERROR: UBT ERROR: Failed to produce item: C:\Users\VR\Documents\UnrealProjects\HelloWorld\PL_Packaged\HostProject\Plugins\UPupilLabsVR\Binaries\Win64\UE4Editor-UPupilLabsVR.dll

I hope you can help me.

Product Version: UE 4.15

I fgured it out my problem was not exactly causded by producing UE4Editor-.dll. My API was missing this parameter InStackSize btw. its zero.

InStackSize The size of the stack to create. 0 means use the current thread's stack size

Thread = FRunnableThread::Create(this, TEXT("PupilMsgWorker"), InStackSize, TPri_AboveNormal);
