since I migrated to ROOT 6, I started to add at the beginning of my “one-main-function” scripts the following lines to make available to this script the class code that I have compiled with
// As of ROOT 6.04, this is the way to expose the symbols of these // compiled libraries into a script. R__LOAD_LIBRARY(PMTtestChannel) #include "PMTtestChannel.hpp"
It works and I do not need to call
gROOT->Load() in some place in the script. However, should I keep these lines if the script, after renaming my-one-main-function() to main(), is compiled to produce an executable?
At the time I thought it was a temporary workaround and I cannot find anymore the source of this information (very likely a forum post). So I am wondering if this is still the correct way to do and if you have a tutorial or any other documentation about this topic. For example it is not mentioned in the User’s Manual chapter “Adding a class” (and I am always afraid that this big manual adapted from ROOT 5 is not representative of the forefront of the ROOT development)
I think that having a how-to/tutorial/official explanation on this topic in a place easy to find would be beneficial
