Hello Xiaorong,
You need to change Dimuon.hh and Particle.hh as attached files.
#include <vector> is needed because vector is referenced in
LinkDef files. You also need default constructor for Dimuon
and Particle class in order to use vector. Compiling libDimun.so
after those changes, try.C works without problem.
Thank you
Masa Goto
