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"

dll.response missing

Hi,

I came across a serious issue for me. I'm getting an error while compiling (in Editor and also out of VS) that says the " \Intermediate\Build\Win64\ProjectName\UE4Editor-ProjectName-9596.dll.response" file is missing. I checked the folder and this is correct. But I'm speechless why. This has happened now several times and everytime I could get my backup running. However it worked last night without a problem and while starting the project today, I got this error. I even zipped my working project yesterday. (I dad this bug yesterday as well, so I went ahead and used my old backup to get it working without the bug and continued zipping this running project). I also checked the given folder in my backup and it's filled with with a massive amount of files "Project-9595.dll", "project-2423.dll" etc. In the current project (with the given error) the folder is empty but 3 files remain:

  1. ProjectName.exe.respone

  2. Makefile.ubt

  3. UnrealHeaderTool.manifest

as I said all other files are missing (see picture) left-side = current project right-side = zip of current project from last night alt text

This is SUPER ANNOYING as I have to create a backup like every time I change something, because I can't be sure the version will still be working the next day. It seems that something causes Unreal to delete all these files. :o

Is there anything that could possible cause this? Or even better: Is there anything that can prevent this?

Thanks for reading,

~Theo

P.S: This only happend to me in 4.9.1

Product Version: UE 4.9

The numbered dlls are work of hot reload, compiler can't modify dll when it's running so UBT creates new dll with number and order engine to unload old dll and load new one.

If you get some error from it, try building without editor open, UBT then deletes all hot reload stuff

Thank you for the explanation. Unfortunately I get another error when compiling without opened editor. It seems that even the one file (projectname.dll.response) without a number is missing. new error where the first line translates into: file XYZ couldn't be opened. errors

for those that can't read it:

Thanks! It actually seems to work! For anybody else experiencing this problem, i did the following:

  1. delete /intermediate folder

  2. right clicked the .uproject and selected "generate visual studio files"

  3. right clicked my projectname (under games) and clicked "build"

  4. right clicked it again after getting an error and selected it as startup project.

I also had this problem but it was due to the fact I used a previous project to build off of. I needed to right click my .uproject file and edit the name like so:
