Vulkan-1.lib packaging error

fabianu · October 31, 2016, 9:41pm

Hi everyone.

I have a strange packaging error i can not figure out. This happens with new created c++ projects and with new created blueprint projects when i add the first c++ class. This does not happen when i export to Windows 32-Bit.

When I try to package for Windows 64-Bit it fails with this error:

UATHelper: Packaging (Windows (64-bit)): UnrealBuildTool: LINK : fatal error LNK1181: cannot open input file 'vulkan-1.lib'

I do not know why the unreal engine is trying to link against vulkan and i don’t know why it’s failing. Please help!

My setup is:

Windows 10 Education 64 Bit
GTX 1080 with GeForce Driver 375.70
UE4 4.13.2
Vulkan SDK 1.0.30.0

Full error message:

Hello fabianu,

When trying to do a general search for the link error you’re getting, I came across this post and it seems like it could be an issue related to build configuration. Could you try what is mentioned there and see if it could help?

As far as the editor trying to link with Vulkan, this is simply due to having the Vulkan SDK installed. Much like having the Android SDK installed, it will automatically pick up on that and start trying to include it where applicable.

Are you using the Binary version of the editor (downloaded from the Epic Games Launcher) or a source built version (downloaded from Github)? Do you get any kind of errors when trying to just compile the project rather than packaging?

Thank you very much for your reply! The solution of the post you linked worked for me. After deleting the Binary and Intermediate folders and compiling with the Development Editor configuration in Visual Studio the packaging succeeded.

I will still answer your questions:
I use the binary version of the engine. And i did not get any compilation errors. Both compiling from Visual Studio and the Engine worked without errors.

Thanks again for the help and have a nice day! Please promote your comment to an answer.
