Hi
referring to this thread

How to build ROOT 6 on Scientific Linux

Hello, I tried to compile ROOT’s master branch on a virtual machine mounting SLC6. The OS doesn’t provide a version of gcc with support for c++11 out of the box, so I installed the devtoolkit and python2.7 as per here. ROOT seems to compile correctly using the g++ version contained in the devtoolkit, but some c++11 features seem to be broken. For example move-constructing a string causes a segfault. Is there a standard procedure to build and use ROOT on Scientific Linux machines that do not h…

it has been stated that Root 6 should not work with devtoolset in Centos6,
but then I have a question, why in root.cern.ch/build-prerequisites
you still suggest to use it ?
If it is only matter of this std::string “bug” inside the cling interpreter,
I would not so much bother…
In my Centos6.7 I have compiled Root6 6.04/08 with gcc.4.9.1 from devtoolset-3 as suggested in the prerequisites, then If I have to use the std library I usually compile my code, and this std::string issue does not appears…
So other than this, are there some strong objection to not use devtoolset to compile root 6?
Thanks

Hi Alfio,

thanks for spotting the reference in the build prerequisites. The reference post is the one you cite by Axel: How to build ROOT 6 on Scientific Linux
I am glad to read that the system is working for you. If problems are encountered, a full compiler installation is the first thing to try.

Cheers,
Danilo
