I restrict my reply to this question. I know almost nothing about 
gtksourceviewmm, but the warning makes me believe that Gsv::wrap_init() 
has not been called. Gtk::Main does not do that for you. Gtkmm does not 
depend on gtksourceviewmm. It's the other way around, gtksourceviewmm 
depends on gtkmm.

Gsv::wrap_init() is called from Gsv::init(). I think you must call 
Gsv::init() early in your program.
