Can't Get Compiled code to run


ROOT Version: 5.34/36
Platform: Not Provided
Compiler: Not Provided


I am new to root and I am trying to compile and run my macroCompile_Code.txt (4.9 KB). The code compiles fine when I use (g++ -L Testing BE_cams_AvgPix.C root-config --cflags --glibs) but when I try to run the compiled code using ‘./a.out’ I get the attached errorCompile_Error.txt (2.1 KB).

Any help would be really appreciated!

Kind Regards,



Hi Rex,

it’s hard to tell. What is the minimal code snippet which reproduces the problem?



It looks like the SetBranchAddress lines has a problem because when I run this code: Compile_Code.txt (1.2 KB) without those 4 lines then it seems to compile and run fine. Thing is, the interpreter seems to read it fine.
Kind Regards,


  TFile *f = TFile::Open("CCD_images_trees.root");
  if ((!f) || f->IsZombie()) { delete f; return 1; }
  TTree *TreeB; f->GetObject("Biases", TreeB);
  if (!TreeB) { delete f; return 2; }
  TH2I *Bias_cam0 = 0, *Bias_cam1 = 0, *Bias_cam2 = 0, *Bias_cam3 = 0;


Hi, sorry, would you mind explaining to me what the difference between what I’ve written and the working version above?
