How can I use the PointCloudEditor to work with point clouds?

[lsyl20]

When I run ./build/PointCloudEditor, an error occurs：
E0807 18:27:10.097451 850578 shader_program_opengl.cc:155] GL Program Linker Error: error: fragment shader input `var2_color' has no matching output in the previous stage
F0807 18:27:10.097476 850578 render_widget.cc:971] Check failed: splat_shader_.LinkProgram()

How can I solve this problem and look forward to your reply！
