Assimp: Microsoft Visual Studio 2017 Building Issue C2678 / C2088

[rathaROG]

Hello! I've got this problem while building with Visual Studio 2017 on Windows 10 64-bit.

3>C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\VC\Tools\MSVC\14.11.25503\include\algorithm(909): error C2678: binary '!=': no operator found which takes a left-hand operand of type 'Assimp::WordIterator' (or there is no acceptable conversion) (compiling source file D:\DEVLibs\assimp\v401\code\X3DImporter.cpp) 1>C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\VC\Tools\MSVC\14.11.25503\include\algorithm(909): error C2088: '!=': illegal for struct

How should I fix this? Please help me!

We are experiencing the very same errors using Microsoft Visual Studio 2017 Version 15.0.26730.12 on windows. However, it builds fine on Linux (centos 7 with gcc5.3.1 and gcc6.3.1) and MacOs X using apple-clang 9.

Thank you so much for your confirm! Looks like it is a bug in the compiler generated assignment operator of Microsoft Visual Studio 2017.

I will try to reproduce it.

That would be great! Thank you so much for that! :)

I believe someone has already fixed this on master. Operator (==, !=) parameters in release builds (4.0.x) are not passed as const references. Commit that fixed it.

Tested it with 9756b48. Works.
Thank you for pointing that out.

I will try later. Thank you guys so much!

9756b48 also worked for me, thanks a lot!
