None Outputting root files in Geant 4 Applications via AIDA

From: Dylan <Dylan>

I am running Geant 4, version 4.9.3, on an iMac running OS X 10.6, with a 64 bit architecture (x86_64).

Currently I am trying to test the histogramming functionality of Geant 4 and its ability to create root files of histograms of longitudinal energy profiles in detector geometries. I plan to include this functionality in my own applications.

I am using the the example applications 'TestEm3' and 'AnaEx01' to try and write histograms of longitudinal energy profiles, in absorber and scintillator, to root files.

However, after installing Root and various versions of AIDA, one by one, I have found none that produce any output when this histogram functionality is invoked in the examples I have tried. I have tried Open Scientist vis, Open Scientist batch, RAIDA and iAIDA.

I have gone through the documentation supplied with Geant 4, the various readme files, made the suggested changes to script files, environment variables and paths. When I used the /testem/histo commands in'TestEm3', no output was produced. I have tried writing the histograms in other formats too, using the UI /testem/histo/setFileType command. I've tried xml, hbook and ascii (via /testem/printHisto), and none of these have worked.

I have also tried the solution suggested in thread #187 and #339, whereby root files should be written without the use of AIDA, in example N02. This did not work on my system either.

If anyone has any insight as to why the histogram classes are not producing output on this system and architecture, I would appreciate your advice.
