Same issue here with the latest build of Pangolin. (The default commit of Pangolin is dated back to 2019, and no longer compiles).

Update: @XinyueZ I resolved this issue by manually compiling and linking OpenGL paths. You can double check the OpenGL paths in cmake config and see it they are all properly set.

Hi there! Could you please tell me how you manually compile and link OpenGL paths? Same issue here but I dont know how to solve it.

I solved this problem.
Add #include <X11/Xlib.h> to EGL.cpp works for me. Maybe you can try this.
