The name 'PublicLibraryPaths' does not exist in the current context (UE5)

DryreL · December 10, 2023, 3:16pm

Hi all,

I’m having an issue when trying to upgrade a plugin from UE 4.27.2 to UE 5.0.3

It says “The name ‘PublicLibraryPaths’ does not exist in the current context” in the error.
I must change this but- to what? Thanks in advance.

using System.IO;
using UnrealBuildTool;

public class CapabilityDetectLibrary : ModuleRules
{
	public CapabilityDetectLibrary(ReadOnlyTargetRules Target) : base(Target)
	{
		Type = ModuleType.External;

		if (Target.Platform == UnrealTargetPlatform.Win64)
		{
			// Add the import library
			PublicLibraryPaths.Add(Path.Combine(ModuleDirectory, "x64", "Release"));
			PublicAdditionalLibraries.Add("CapabilityDetectLibrary.lib");

			// Delay-load the DLL, so we can load it from the right place first
			PublicDelayLoadDLLs.Add("CapabilityDetectLibrary.dll");
		}
        else if (Target.Platform == UnrealTargetPlatform.Mac)
        {
            PublicDelayLoadDLLs.Add(Path.Combine(ModuleDirectory, "Mac", "Release", "libCapabilityDetectLibrary.dylib"));
        }
	}
}

I assume it’s all .lib files? You can use:

string LibPath = Path.Combine(ModuleDirectory, “x64”, “Release”);
foreach (string file in Directory.GetFiles(LibPath, “*lib”))
{
PublicAdditionalLibraries.Add(file);
}

Thanks for the code!

I’m having following error when trying to open my project (Build was successful).

SOLUTION:

PublicLibraryPaths is outdated. Make sure to use PublicIncludePaths.

Additional info (directly from the compiler): Library ‘YOURFILE.lib’ was not resolvable to a file when used in Module ‘YOURFILE’, assuming it is a filename and will search library paths for it. This is slow and dependency checking will not work for it. Please update reference to be fully qualified alternatively use PublicSystemLibraryPaths if you do intended to use this slow path to suppress this warning.
