Error during building the extension

I am using ubuntu 18.04 and I get the following error after executing cmake --build .

coppelia/simExtAssimp/plugin.cpp:107:65: error: ‘aiProcess_DropNormals’ was not declared in this scope aiProcess_SortByPType|aiProcess_RemoveComponent|aiProcess_DropNormals| error: ‘aiProcess_EmbedTextures’ was not declared in this scope aiProcess_GenUVCoords|aiProcess_TransformUVCoords|aiProcess_EmbedTextures;

Hello, make sure to use the latest source for Assimp (CoppeliaSim is currently using Assimp version 4.1). Cheers

@Coppelia : thanks for the quick response.

I can compile simExtAssimp using assimp from head (https://github.com/assimp/assimp). But obviously when I copy libsimExtAssimp.so to the CoppeliaSim_Player_V4_0_0_Ubuntu18_04 then it crashes with

If I install assimp 4.1 instead then I get this error when building simExtAssimp:

Doesn't the library that comes with CoppeliaSim V4.0.0 work? Have you taken the version of simExtAssimp from release 4.0.0 or the last version of it? The last version of it is using API calls that are not supported in V4.0.0 (but will in V4.1.0 to come out next month)
