Hi,
me I had your problem few times.
It comes because in your build-*/ folder, where all plugins*.cpp are 
stored,
it may happen that two of these plugin* file contain the same line, like 
for example:

in plugins0.cpp:
#include 
"/home/3S-LAB/ecatalano/Yade/yade/pkg/dem/Engine/GlobalEngine/GlobalStiffnessTimeStepper.cpp" 


and the same in plugins1.cpp:
#include 
"/home/3S-LAB/ecatalano/Yade/yade/pkg/dem/Engine/GlobalEngine/GlobalStiffnessTimeStepper.cpp" 


so that you have a "multiple definition" error.

To solve the problem, it is sufficient to delete the line from one the 
two files.

Much better, especially in the case of several cases like this one, is 
to type

"scons -c"

and then recompile, type "scons".

Ema
