ROOT production release v6.14/00 is out!

@Axel should we pin this?

uzair90 · June 15, 2018, 5:15am

I have been trying to build ROOT 16.14/00 with Ubuntu 16.4 and GCC 4.8.0.

I get the following error every time I run “cmake --build .” in the build directory:

3 posts were split to a new topic: Windows install issue with v6.14/00

Done, thanks for reporting! It will be part of a v6.14/02 that we expect in a couple of weeks.

Some more info on the fresh new RDataFrame interface in this post.

@uzair90 Please try again with GCC 4.8.5 or newer. ROOT needs full support for C++11, and GCC 4.8.0 does not have it yet.

Edit: This specific problem may actually be a problem with dependencies in CMake, however (see ROOT-9478).

Axel · June 16, 2018, 7:24am

And Ubuntu 16.04 comes with GCC 5.3.

Hello,
I am also having trouble with root installation. This is the error I am getting:

[ 88%] Generating G__ROOTVecOps.cxx, ../../lib/libROOTVecOps_rdict.pcm, ../../lib/libROOTVecOps.rootmap
In file included from input_line_12:7:

This is my gcc version ubuntu 18.04:
gcc (Ubuntu 7.3.0-16ubuntu3) 7.3.0

How do I fix this issue?

Thanks,
Arka

Hi Arka,

see Guilherme’s comment in the linked Jira ticket: Loading...

you should add the line

set_property(GLOBAL APPEND PROPERTY ROOT_BUILTIN_TARGETS VDT)

right after line set(vdt ON CACHE BOOL "" FORCE) in file cmake/modules/SearchInstalledSoftware.cmake.

Cheers, Axel.

amadio · June 18, 2018, 6:43am

Alternatively, without making any change to ROOT, you can do (in the build directory):

$ cmake --build . --target VDT
$ cmake --build .

The problem is that CMake fails to add a dependency on VDT, so it is not built early enough.
This is being fixed here: https://github.com/root-project/root/pull/2205.

arkasantra · June 18, 2018, 9:49am

The problem is fixed. Thank you very much.

amadio · June 18, 2018, 9:51am

It’s also fixed on the master and 6.14 branches as well, so when 6.14/02 is released, this will not be a problem anymore. Cheers,

Hi,
Will there be a binary distribution of v6.14 compatible with SLC 6.9? This doesnt seem to be the case at the moment. Hence one cannot set it up on lxplus - SLC 6.9 from CVMFS either.
And trying to compile ROOT v6.14 on SLC 6.9 runs into other problems, such as requiring cmake version 3.4.3 which doesnt seem to be available for SLC 6.
Any suggestions would be very welcome.
Thanks
Halil

Hi

I am new to jupyter

can we install python 2 and 3 on same system through Jupyter

Axel · June 19, 2018, 6:29pm

You could simply log on to lxplus7.cern.ch. Would that be a solution for you?

Axel · June 19, 2018, 6:31pm

Hi priyanka_120993, could you open a new topic for this?

Axel

hsaka · June 20, 2018, 12:44am

Hi Axel,
Sure, that works in principle. However bulk of the input samples I would like to work with are not stored on lxplus but in other machines where the OS is still SLC 6 (probably a fairly common situation). Is there a fundamental reason why an SLC 6.9 binary is difficult to centrally provide? I understand that CentOS 7 is the next step but this will really save a lot of hassle until the transition is complete. Normally I wouldnt mind not having the latest version of ROOT, but this one surely deserves an update
Thanks
Halil

Axel · June 20, 2018, 6:24am

Hi Halil,
SLC6’s compiler (GCC4.4!) is too old to build ROOT - GCC 4.4.0 is from 2009! Use LCG releases to create a custom environment (but then e.g. emacs is broken etc), or simply log on to lxplus7 where the compiler is old, too, but just recent enough.
Axel.
