By running main.cc and with data.root, I should make analyzetree.root output file, but it seems the code is not working and I don’t see any error. Please give me your insight.
main.cc (2.5 KB)
Please read tips for efficient and successful posting and posting code
ROOT Version: root_v5.34.36
data.root file too big to be upload.
here is the link * Download example data tree: [root]
One cannot try your code without “
But first, make sure that you do not get any errors or warnings from:
`root-config --cxx --cflags` -Wall main.cc `root-config --libs`
particle_tree.h (2.0 KB)
Here is “particle_tree.h”
Fix your source code.
[...]$ `root-config --cxx --cflags` -Wall main.cc `root-config --libs`

I changed the name of analyzetree.cc to main.cc with little bit modifying such as from exe/analyzetree.exe <No. events to analyze>
exe/analyzetree.exe data.root analyzetree.root 1000
Here is the raw analyzetree.cc

The problem is not the “main” routine but the missing implementations of the “particle_tree” class methods.
analyzetree.tgz (7.5 KB)
here is the everything the file contain except data.root. Is there still error?
In the “
analyzetree.cc” file, instead of:
Are there any other things I should know. When I run this code, word usage appear and root quits.
It is not a ROOT macro. It is a “standalone application”. You must learn how to compile and run executables on your system.
