It's still giving me the same error even though I changed the file display_x11.cpp Note: I am using Ubuntu 18.04 in mac os X.

I think something may go wrong with the 3D rendering, could you please check by run glxgears : http://www.upubuntu.com/2013/11/how-to-check-3d-acceleration-fps-in.html

If this has some problem, then, pls let me know.

Muhammad1331 commented 5 years ago

I checked the glxgears which are running fine in my ubuntu. I tried to google the problem but couldn't find any plausible solution. I would really appreciate if you can help me with that.

EricLYang commented 5 years ago

Another question, how much is your RAM, this ORB SLAM could take you 8G.

Muhammad1331 commented 5 years ago

This is my mac system configuration. MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports) Processor 2.3 GHz Intel Core i5 Memory 8 GB 2133 MHz LPDDR3 Graphics Intel Iris Plus Graphics 640 1536 MB

BTW while I run the code the simulation gives me a glimpse of windows then it just stopped.

You can try following 1) Go to Software & Updates 2) Click Additional Drivers 3) Select the proprietary driver and click Apply changes After the driver is installed restart the computer

hi ! This problem because of the Eigen version in Ubuntu18.04 is 3.3.4, you can solve this issue by replacing your eigen version to 3.1.0.
