Hello Adolf, Sorry for not being faster at this… Still catching up :) This is basically a variable which used to be called MACHINE but was replaced with xxxMACHINExxx because the string “MACHINE” was actually used in some filename. Not sure I am happy with that name… When the root files are generated, we don’t replace anything, but if we read a rootfile from config/rootfiles, we will replace this variable with the architecture we are building for. Sometimes this method allows us to have just a generic root file for all architectures, sometimes this does not work because there are extra files or something like that. So when you have such a case, you need to manually replace the architecture with the placeholder and check if all other architectures generate the same file. -Michael > On 5 Jul 2024, at 11:39, Adolf Belka wrote: > > Hi All, > > When a rootfile is in one of the specific architecture directories, e.g. aarch64 do all the aarch64 references just get left as that or should they get changed to xxxMACHINExxx. > > Looking at some files in the directories it looks like they get left alone but when I have done the samba rootfile update for x86_64 I have , most times, changed any x86_64 reference to xxxMACHINExxx. > > What is the correct approach so I don't go messing things up. > > Regards, > > Adolf >
