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"

An issue with hot reloads from 4.15.0 resurfaced in 4.16


Bumped into the issue with lib/dll suffix number mismatching when compiling the project for hot reload today.

I remember exactly the same issue that originally appeared in 4.15.0 but has been fixed in 4.15.1. And now it's back in 4.16. I get it in both 4.16.0 and 4.16.1

I observe the following disparity in the compiler output:

 1>  [2/3] Link UE4Editor-ProjectName-744.dll
 1>  [3/3] Link UE4Editor-ProjectName-3960.lib

which results in this error:

 1>ERROR : UBT error : Failed to produce item: C:\UE4-Projects\ProjectName\Intermediate\Build\Win64\UE4Editor\Development\UE4Editor-ProjectName-3960.lib

because the actual lib output is UE4Editor-ProjectName-744.lib

This doesn't happen every time but I couldn't figure a pattern so far. Some times it works but much more often it doesn't.

The old issue in the tracker just in case: https://issues.unrealengine.com/issue/UE-42205

Product Version: UE 4.16

Hi bstone,

Thanks for pointing this out. It does look like this issue has returned in 4.16. I have re-opened the original ticket to have it looked into again.
