Ivo@2: /* To compile, you may have to specify:
Ivo@2:  *  The include paths for mono: -I /usr/include/mono-1.0/ -I /usr/include/glib-2.0/ -I /usr/lib/glib-2.0/include/
Ivo@2:  *  The location of the VBoxXPCOMC.so library: /usr/lib/virtualbox/VBoxXPCOMC.so
Ivo@2:  *  The location of the mono library (if an alternative build is to be used): /home/ivo/mono/devtest/lib/libmono-2.0.so
Ivo@2:  *  To link against the mono library (if the system wide installed version is to be used): -lmono
Ivo@2:  *  Where to look for the VBoxXPCOMC.so library at run time: -Wl,-R,/usr/lib/virtualbox
Ivo@2:  *  Where to look for the mono library at run time (if non-standard): -R,/home/ivo/mono/devtest/lib/
Ivo@2:  *
Ivo@2:  * The resulting commandline may look like this:
Ivo@2:    gcc VBoxMono.c -o VBoxMono -lmono \
Ivo@2:     -I /usr/include/mono-1.0/ -I /usr/include/glib-2.0/ -I /usr/lib/glib-2.0/include/ \
Ivo@2:     /usr/lib/virtualbox/VBoxXPCOMC.so -Wl,-R,/usr/lib/virtualbox
Ivo@2:  * The resulting commandline may look like this if mono is installed in an alternative location:
Ivo@2:    gcc VBoxMono.c -o VBoxMono \
Ivo@2:     -I /usr/include/mono-1.0/ -I /usr/include/glib-2.0/ -I /usr/lib/glib-2.0/include/ \

Ivo@2:     /home/ivo/mono/devtest/lib/libmono-2.0.so -Wl,-R,/home/ivo/mono/devtest/lib/
Ivo@2:  * Then make the binary owned by root and set the suid bit:
Ivo@2:    sudo chown root VBoxMono
Ivo@2:    sudo chmod u+s VBoxMono
