Cannot open input file 'HACD_64.lib' ;_;

[anonymous_user_a4d67e591 (anonymous_user_a4d67e59)]

Hi guys.

I’m getting this sad error when I try building:

error LNK1181: cannot open input file 'HACD_64.lib'

I understand that HACD is a 3rd party plugin (Long name is Hierarchical Approximate Convex Decomposition), but I can’t figure out how to fix this problem.

Looks like it can’t find a file by the name of HACD_64.lib. I reinstalled the ue4 engine, but it didn’t work.
Anyone know how to fix this? I’m really stuck once again. ;_;

Many thanks

I figured it out, thank God! Here’s the fix:

[BUG] LNK1181: cannot open input file

This is the answer found there:

Okay, so sometimes it’s better to start with a clean slate. I’d had some stale files from various builds in different configurations lying around. After doing the following:

deleting the Binaries/ and Intermediate/ directories

right-clicking my .uproject and selecting “Generate Visual Studio Files”

in Visual Studio, right-clicking my project in the Solution Explorer and selecting “Rebuild” with the Development Editor configuration

The issue resolves itself. I’d still like to know why using the Debug configurations appends the weirdness to the .dll and .lib files as in my original question, causing the original issues. However, for now this is solved.
