Hi folks:

I have been eager to get a development environment for OpenVibe together on my Apple laptop.

I hope that I could build OpenVibe in Neurodebian running on VirtualBox. I was able to get the code to compile fully, but it nevertheless throws errors on startup there, and never actually runs (see below).

Thank you. I would sincerely appreciate anyone's advice on how to get a system like this configured.

============
./linux-test

Hi Mark,

this is tricky as the errors printed appear to be due to graphics which in openvibe is handled by gtk and/or ogre -- those are not printouts from openvibe itself but some graphics related library subroutine. One way to proceed would be to check that your virtual machine has 'full' graphics capabilities and can run other gtk and ogre applications in X11. If so, then you could investigate whats the issue with those missing drivers it complains about like vboxvideo etc. Usually such errors indicate that you haven't installed some necessary packages on your distro and/or the vm is not configured for graphics.

If that doesn't sort it out, I'd step the openvibe code with gdb and see which call exactly produces the error, and then find out if that call at all works on your system or if its something related to the way openvibe uses it.


Good luck,
Jussi

Thank you Jussi. That answer is a bit daunting, but I appreciate it very much.
