error: if a fragment input is (or contains) an integer, then it must be qualified with 'flat'

See original GitHub issue

Hi, I’m also trying to preprocess the data but am getting a different OpenGL error:

OpenGL Error: XX (500) In: /usr/local/include/pangolin/gl/gl.hpp, line 203 Framebuffer with requested attributes not available. Using available framebuffer. You may see visual artifacts.GLSL Shader compilation failed: <string>: 0:8(1): error: if a fragment input is (or contains) an integer, then it must be qualified with ‘flat’ 0:8(8): error: `gl_PrimitiveID’ redeclared

Zero samples are successfully being generated. I’m trying to generate the chairs training dataset from ShapeNet Core v2.

I am running this code on a fresh VMWare VM of Ubuntu 18.04 64-bit on VMWare Workstation Player 15. I have an NVIDIA GTX 1060 Mobile.

Some previous things I’ve tried were:

Running in a Docker contain (but Pangolin required a display)
Running in a VirtualBox VM of Ubuntu 18.04 (but it did not support OpenGL 3.3)
