I have a root file which I was trying to analyse. I created a class for this root file using MakeClass method. ( Please find the code attached with this mail.)
I am reading the data from the root file ..do some caclulation and store output in other output root file with a tree. During this process I use TLorenzeVector which make things little easier for me.
As soon as I add the following line at the last part of my code it gives me segmentation voliation.... otherwise it works fine. Infact If i add these line at some other place it gives the same errror. Error occures at Tree.Fill() line!!
You must provide a dictionary for the vector in order for the I/O to work.
To do so is as simple as adding the following lines towards the top of your file:#include <vector>
#include "TLorentzVector.h"
#ifdef __MAKECINT__
#pragma link C++ class vector<TLorentzVector>;
#endif and you need to compile the result with ACLiC:.L Analyzer.C+Note: you may have to correct C++ syntax error if you took advantages of CINT shortcuts
Thanks for the help.
I have included the lines you sent........I am just confused when to run this command .L Analyzer.C+ ???
As I use a makefile to make "Analyser.so" and then run the code as :
Now should I generated the dictionary before doing these or have to modified my make file?? and how?
Meantime it seems the dictionary is not gereated… with .L Anlyser.C+ command… I am using 5.14 version.
Here is the output of .L Analyser.C+

Probably your macro uses something rootcint can’t parse.

[quote] As I use a makefile to make “Analyser.so” and then run the code as : [/quote]Since you have your own makefile and, seemingly, you are already running rootcint and compiling the result of running rootcint, you simply need to add the line#pragma link C++ class vector<TLorentzVector>; to you linkdef file.

How I can make a linkdef.h file and complie it also ??
Now the code compiles but again the same problem!!! If I declare one more TLorenzeVector then I get the segmentation voilation…This is excactly I was getting in the beginng.
Then I don’t know what the problem really is and I would need a complete running example to be able to debug the problem and/or you might be able to find the cause by using valgrind.
You must initialize your variable, in particular the array size (by the way, they are actually never set but I assume this is work in progress):[code] Int_t pPhot_N = 0;
Int_t pJet_N = 0;
Int_t gJet_N = 0;
Int_t Events = 0;
