Hi Philippe,
The last root version that worked good for me was root-6.06.08,
and this is the one that I am using right now after failing in using root-6.08.02.
I am now trying with root-6.08.04 as you suggested…
In the mean time, I would like to make the following observations in respect to these new versions of root (root-6.08.xx):
- cmake: The configure process, driven by cmake, takes ages!
I measured the time needed in our cluster login node (Processor (INTEL CPUs (E5-2640 v3) Operating system: CentOS Linux release 7.3.1611) -> 11:20 (yes, 11 minutes!). And this is just the configuration process not the build.
‘configure’ in previous root versions (root-6.06.xx) needed only 18 seconds to be completed in the same machine.
The ‘cmake’ procedure also needs two copies of root, one for the sources and one for the build.
(One could delete the sources after the build, but in case that you want to keep it to change something in the source you will need it again. So, in the end, I have to keep these two copies).
I’ve always liked the simplicity of installing root by defining ROOTSYS, typing ‘configure’ and then ‘make’. This seems to not to be possible anymore. There is even a warning in ‘configure’ saying that this method is deprecated. Nevertheless I tried and I got compilation errors, so it didn’t work.
Cheers,
Alberto
