Hello 
After integrating the example for generating mesh components at runtime (A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums - I took the code from the github example (ProceduralMeshComponent)) in my Unreal Engine 4.7.6 project I faced the following error:
error LNK2019: unresolved external symbol ""__declspec(dllimport) public: static void __cdecl FWindowsPlatformMisc::MemoryBarrier(void)" (__imp_?MemoryBarrier@FWindowsPlatformMisc@@SAXXZ)" in Function ""public: struct FLockFreeVoidPointerListBase::FLink * __cdecl FLockFreeVoidPointerListBase::FLinkAllocator::AllocateLink(void *)" (?AllocateLink@FLinkAllocator@FLockFreeVoidPointerListBase@@QEAAPEAUFLink@2@PEAX@Z)". [...]\Intermediate\ProjectFiles\GeneratedMeshComponent.cpp.obj
I had this error already before (in my 1 week since I’m working with Unreal) and solved it by implementing
static void MemoryBarrier() { }
(as shown here: Project fails to compile - C++ - Epic Developer Community Forums). This method is still there but that doesn’t seem to influence the error since this searches for an dll (__declspec(dllimport)). My first thought was to rebuild the engine so that the above fix is contained in the dll. But by doing so, I recognized that VS2013 only printed 2 lines at build:
1>------ Build started: Project: UE4, Configuration: BuiltWithUnrealBuildTool v64 ------
========== Build: 1 successful, 0 error, 0 actual, 0 skipped==========
(freely translated from german). I guess this is due to the given command lines in the project properties under “NMake” with are:
@rem Nothing to do.
Is this due to, that I have invoked “Generate project files” on my project?
I don’t have any clue how to solve this error or even how to rebuild the engine (if this would even help). I appreciate any help!
I hope, I mentioned all important things, you need to know.
Thank you very much!
