Hi, The ROOT team is happy to announce the new production release v6.14/00! It contains several major new features, including: LZ4 compression by default: faster reading of ROOT files; ROOT::RDataFrame : the recommended way for analyzing trees, simple, expressive and parallel - see https://root-f…

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

[image] suhl: In master this seems to be fixed by commit 5c1921a4be42c195c4490521de35774f5f1a2aa0, could this be cherry-picked to the 6.14 branch as well? 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 .

[image] uzair90: I have been trying to build ROOT 16.14/00 with Ubuntu 16.4 and GCC 4.8.0. @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 CMak…

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: /home/arka/Root6_Build/include/ROOT/RVec.hxx:36:10: fatal error: 'v…

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.

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/…

[image] amadio: cmake --build . --target VDT The problem is fixed. Thank you very much.
