Hej, I’m getting a similar error to this

Adding the line in Build.cs doesn’t work unfortunately. Any other module I have to add there?

[1/4] Compile MyComponent.cpp


[2/4] Link UE4Editor-MyProject-Mac-Debug.dylib


Undefined symbols for architecture x86_64:


  "FRenderResource::InitResource()", referenced from:


      vtable for FTexture in MyComponent.cpp.o


  "FRenderResource::ReleaseResource()", referenced from:


      vtable for FTexture in MyComponent.cpp.o


  "FRenderResource::~FRenderResource()", referenced from:


      FTexture::~FTexture() in MyComponent.cpp.o


ld: symbol(s) not found for architecture x86_64

I have tried to run verbose mode to find out something more, but I have no idea how to (as said in line 31 of the above log)…

I have sorted it out.

In MyProject.Build.cs the line has to say:

PrivateDependencyModuleNames.AddRange(new string[] { "RenderCore" });
