Hi, Are you running the LSD-SLAM in a virtual machine???

Moha555 commented 7 years ago

Hi, yes

af-silva commented 7 years ago

Hi,

That is a hard problem to solved without seeing what is going on in the machine. Bu you can try to enable hardware acceleration in your Virtual Machine and make sure that you have the VirtualBox Extension Pack installed. If the problem persists try to look around for the specific error that you are getting when trying to run the code libGL error: failed to load driver: vboxvideo .

And I don't have experience running this code on a virtual machine, so I don't know how it behaves, but from my experience the LSD-SLAM uses a lot of resources from the machine and in a virtual environment can be a little slow...

Sorry if I can't help you more than this :)

I have the next error running lsd_slam_viewer lsdslamerror

Moha555 commented 7 years ago

Dear @af-silva My problem is solved... :) Virtual machine could not run this code I tried to run it on the Ubunto OS , and eventually it's ran.

@romdos I thinks it's better to you to create a Issue related to the problem that your project instance is invoking. Second please provide more information, because just with the error is very difficult to help (e.g. are you using rosbuild or catkin? ). You could try to delete the devel and build folders and compile everything again... it's a memory problem but I don't know what is causing it.

@Moha555 Nice :) happy hacking :p If the problem is solved please close the issue, to maintained the issue list clean.
