Hello Sylvain,
One may suspect you didn't load all DLL's properly or you didn't compile
your code the consistent way.
Can you elaborate whether you can run your code as ROOT macro
and as standard ROOT-loadable DLL?
At least when one uses macro it leaves no room for any bug withn the
compilation option. When you create a ROOT-loadable DLL you are free of
the problem with the proper loading of the ROOT system DLL's.
Since your code is a simple one it can be run as ROOT macro. Can you try
that first? If the performance is your main concern then try
ROOT-loadable DLL as your next step.
Best regards, Valeri
