ERROR! FAILED TO INITIALIZE GLFW LIBRARY

[wuzijian1997]

Hi Adnan,

After building the AMBF as the instruction here, I met below error when running ambf_simulator. I am using Dockerfile (Ubuntu 20.04 with ROS Noetic) according to this repo. Do you know how to fix this problem? Thank you!

Hello,

Thanks for the issue. If you are running ambf_simulator via Docker, you will not get the GUI to work. Instead you can run the simulator headless using ambf_simulator -g 0. Please see here for more command line options.
