[osg-users] Weird linker error while building an osg-based app on a virtual machine

[Andreas Goebel]

Ok,

in case someone runs into the same problem: The linker error disappears
when you switch off 3d accelleration for the virtual machine.

After linking, you can turn it on again, and then even the application
works.

I have no idea what linking has to do with 3d accelleration while the
program is not even run.
