Symbol definition confusion

daviddoria

I have a bunch of files that I would like to combine into a library. In the makefile I have

1 2

libgeom.a: geom_Point.o geom_Vector.o geom_Matrix.o geom_Line.o geom_Edge.o geom_Plane.o geom_Polygon.o geom_Display.o geom_Geometry.o
        ar crs $@ $^

it seems to work fine. However, when I try to use the library I get an undefined symbol. When I run nm on it, it seems like there is a symbol that is undefined 3 times and defined once???

1 2 3 4 5

nm libgeom.a | grep VectorC1Eddd
         U _ZN11geom_VectorC1Eddd
         U _ZN11geom_VectorC1Eddd
         U _ZN11geom_VectorC1Eddd
00000046 T _ZN11geom_VectorC1Eddd

I don't understand how that could be? Am I interpreting this output incorrectly?

Thanks!

Dave
