Looking into it, this is not this plugins issue but more of an engine not supporting clang 6 yet officially(Although it builds and compiles ok).

[rdeioris]

Hi, the error is present in clang-3.9 too. I am investigating if i can bypass it

[aknarts]

I found a way to bypass it but it requires modification of the fbxproperty.h which is not really desirable from the plugin standpoint.

Just for the posterity this works:(line 1188 in Engine/Source/ThirdParty/FBX/2018.1.1/include/fbxsdk/core/fbxproperty.h)

 return StaticInit(pObject, pName, FbxGetDataTypeFromEnum(eFbxEnum), pValue, pForceSet, pFlags); // return StaticInit(pObject, pName, FbxGetDataTypeFromEnum(FbxTypeOf(*((FbxReference*)0))), pValue, pForceSet, pFlags); 

After this the errors move a bit further(working on it).

I might just be building it wrong at this point

Hello, I experimented the same error with the FBX module when compiling with clang-3.9 on the new Ubuntu-18.04 (clang-3.8 is no more available on that distribution). The fix you propose @aknarts works pretty well. So modifying line 1188 in Engine/Source/ThirdParty/FBX/2018.1.1/include/fbxsdk/core/fbxproperty.h is sufficient:

return StaticInit(pObject, pName, FbxGetDataTypeFromEnum(eFbxEnum), pValue, pForceSet, pFlags); // return StaticInit(pObject, pName, FbxGetDataTypeFromEnum(FbxTypeOf(*((FbxReference*)0))), pValue, pForceSet, pFlags); 

Thank you!
