It looks like the standard C++ library is not getting linked in. Are you linking your code with g++, gcc or ld? If using the first, that library gets linked in automatically, but not if you're using the other two.

For the errors about sqlite3, you need to add -lsqlite3 to the link command (assuming you have it installed, of course).
