 From the log it's a stdc++ library issue. Hard to tell from here why it 
cannot be linked successfully. You have the stdc++ header files, so it's 
rather odd that the linker fails. The stdc++ library should come with 
the C++ compiler, and should be automatically linked in, without 
mentioning it in the g++ command line.

In principle yes. The logger is quite flexible. It supports many logging 
groups and levels, as enabling all logging slows down VirtualBox to a 
crawl. Also you can have every log line prefixed by time and thread stamps.
