Dear Masa,
Thanks for your reply. Sorry I still can not get it work. Could you tell
me where I should put those command. I tried following two way.
1) I add
#include <vector>
...class
#ifdef __MAKECINT__
#pragma link C++ class vector<Particle>;
#endif
in Particle class header file
#include <vector>
...class
#ifdef __MAKECINT__
#pragma link C++ class vector<Dimuon>;
#endif
in Dimuon class header file
when I run the root micro file I got
*********************
root [0] .L try.C
root [1] main()
Error: Can't call vector<Particle,__malloc_alloc_template<0>
>::push_back(*muon1) in current scope FILE:try.C LINE:29
Possible candidates are...
filename line:size busy function type and name (in
vector<Particle,__malloc_alloc_template<0> >)
*** Interpreter error recovered ***
root [2]
**************************
2) I wrote DimuonLinkDef.h and ParticleLinkDef.h files
and in Makefile.am I added
noinst_HEADERS = \
ParticleDict.h ParticleLinkDef.h \
DimuonDict.h ParticleLinkDef.h
I got same error message like before.
Thanks for your time!
Xiaorong

Hello Xiaorong,
I am happy to answer your question.
This is a Cint limitation. You have STL container classes
vector<Dimuon> and vector<Particle> interpreted. they
work to some extent, but not perfect. You'll find this kind
of problem as you go on. Solution is to precompile
vector<Dimuon> and vector<Particle> in libDimuon.so
using #pragma link statement.
#include <vector>
class Particle { .... };
class Dimuon { .... };
#ifdef __MAKECINT__
#pragma link C++ class vector<Dimuon>;
#pragma link C++ class vector<Particle>;
#endif
Then, things will be fine.
Thank you
Masa Goto
