In short:

Install guest-os-additions

Create easy accessible symbolic link:
sudo ln -s /media/sf_Share /home/<>/Share

Enable auto-mount for the shared folder:
You may go to Device->Shared Folder Settings, edit the shared folder, and enable Auto-mount.

make-googleearth-package --force
sudo apt-get install gdebi
sudo gdebi googleearth*.deb

Import olsrd into Eclipse

This is to avoid all sorts of red markers on the right hand side (potential compilation errors). I have not yet tried to compile this. Just browsing at the moment:

  1. Create new makefile project with existing code.
  2. Set project path to be the top directory olsrd.
  3. Make sure to select the Linux toolchain (or the correct one for your environment).

That’s it.


If problems starting Xming applications, disable some security on the windows machine.
