UE 4.15.2 Compile Error

[mukund-dh]

Hey I get the following error when I try to compile this with UE 4.15.2:

error C2504: 'TStructOpsTypeTraitsBase2': base class undefined

TStructOpsTypeTraitsBase2 is not a template Line 72, RuntimeMeshComponent.h

I'm also getting build errors with 4.15.2. This is the error I'm getting:

I was able to fork and fix this: https://github.com/Revolutionary-Games/UE4RuntimeMeshComponent

I can create a pull request if that is a sufficient fix.

And that's what I get for trying to rush through a 4.16 fix... That's actually been upgraded for 4.16 but for some reason didn't think to preprocess switch the old version back in for previous engines.

[Koderz]

Hopefully that's fixed but don't have 4.15 installed atm so can't verify that.

I'm also getting build errors with 4.15.2: d:\unrealengine4\ue_4.15\engine\source\runtime\coreuobject\public\UObject/Class.h(662): error C2280: 'FRuntimeMeshComponentPrePhysicsTickFunction &FRuntimeMeshComponentPrePhysicsTickFunction::operator =(const FRuntimeMeshComponentPrePhysicsTickFunction &)': attempting to reference a deleted function 2> (...) =FRuntimeMeshComponentPrePhysicsTickFunction (...)

Tried to use forked version and here what I get: Time Elapsed 00:01:31.03 ========== Build: 2 succeeded, 0 failed, 0 up-to-date, 0 skipped ========== :D

Hello,

All existing issues for RMCv2 are being closed as RMCv2 is no longer being supported. RMCv3 is in beta here : https://github.com/Koderz/RuntimeMeshComponent/tree/Version3Dev

If you encounter this or any new issues in v3 please feel free to open a new issue!

Thanks!
