1 /* To compile, you may have to specify:
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/
3 * The location of the VBoxXPCOMC.so library: /usr/lib/virtualbox/VBoxXPCOMC.so
4 * The location of the mono library (if an alternative build is to be used): /home/ivo/mono/devtest/lib/libmono-2.0.so
5 * To link against the mono library (if the system wide installed version is to be used): -lmono
6 * Where to look for the VBoxXPCOMC.so library at run time: -Wl,-R,/usr/lib/virtualbox
7 * Where to look for the mono library at run time (if non-standard): -R,/home/ivo/mono/devtest/lib/
8 *
9 * The resulting commandline may look like this:
10 gcc VBoxMono.c -o VBoxMono -lmono \
11 -I /usr/include/mono-1.0/ -I /usr/include/glib-2.0/ -I /usr/lib/glib-2.0/include/ \
12 /usr/lib/virtualbox/VBoxXPCOMC.so -Wl,-R,/usr/lib/virtualbox
13 * The resulting commandline may look like this if mono is installed in an alternative location:
14 gcc VBoxMono.c -o VBoxMono \
15 -I /usr/include/mono-1.0/ -I /usr/include/glib-2.0/ -I /usr/lib/glib-2.0/include/ \
16 /usr/lib/virtualbox/VBoxXPCOMC.so -Wl,-R,/usr/lib/virtualbox \
17 /home/ivo/mono/devtest/lib/libmono-2.0.so -Wl,-R,/home/ivo/mono/devtest/lib/
18 * Then make the binary owned by root and set the suid bit:
19 sudo chown root VBoxMono
20 sudo chmod u+s VBoxMono
