I believe the errors are due to that you link the same .o-file
twice.. Remove one of them..

hmm maybe put ugl_view _after_ ugl_desktop on the commandline? A
normal ld does only a one pass scan for symbols if my memory doesn't
fool me too much..

Guess a better commandline would be something like:

gxx -g3 -fno-implicit-templates -fhandle-exceptions -I. -I../ -I./include \
     -o ugltest ugltest.cc universe.o smath.o timer.o oolist.o input.o \
     llist.o inilib.o ugl_bitmap.o ugl_desktop.o ugl_view.o uobject.o \
     vertex.o vector.o object.o  ugl_window.o ugl_palette.o ugl_screen.o \
     ugl_component.o ugl_container.o -L../ -lalleg
