It's nothing specific to boost, you just have to learn the GDB macro language. One of the difficulties in writing GDB pretty prints is that, unlike with Visual Studio debug visualizers, GDB pretty printing does not happen "automatically". You have to write a special command for every single type you want to pretty print. "printboostvariant", "printboostany", "printboostfspath", etc. It's a little bit annoying for sure. You can get around this even by writing a GDB plugin. To learn the GDB macro syntax just google for "gdb macro syntax". Additionally, you can refer to this page: http://www.yolinux.com/TUTORIALS/GDB-Commands.html#STLDEREF which, specifically contains this .gdbinit file (which is where you add macros) http://www.yolinux.com/TUTORIALS/src/dbinit_stl_views-1.03.txt that contains many examples of pretty printing STL containers. If you want to write a GDB plugin, there is not as much available info, but you can refer to this page: http://sourceware.org/ml/gdb-patches/2008-05/msg00671.html in which someone submitted a plugin for GDB to automatically display correctly STL types just by using the normal "print" statement.
