Hi,
Carrot should work with ROOT version > 3.02.
Although a problem would appear in executing child init script
http://carrot.cern.ch/CarrotExamples/CarrotChildInit.C
This script loads several ROOT libs and executed when apache cihild
process is spawned. Since some ROOT libraries have dependences
an order of loading is not arbitrary. Unfortunately the order could be
changed when one switches to another ROOT version. If you have ROOT
sources you can find ROOT libs dependences by looking at config/Makefile.win32
I do not know at the moment how to determine libs dependencies by looking at compiled libs.
If sombody knows how to do it, please, let me know.
I hope to find solution for it by next Carrot release.
For a time being try changed order of ROOT libs loading in CarrotChildInit.C as
ret &= !gSystem->Load("libMatrix"); // moved up
ret &= !gSystem->Load("libHist"); // moved up
ret &= !gSystem->Load("libGraf");
ret &= !gSystem->Load("libGpad");
// ret &= !gSystem->Load("libMatrix");
// ret &= !gSystem->Load("libHist");
ret &= !gSystem->Load("libTree");
ret &= !gSystem->Load("libGraf3d");
ret &= G__loadfile("TApacheConfig.h");
Hope this helps. Thanks for pointing the problem.
Regards. Valeriy
