ROOT

Hi,
I installed ROOT 6.26.00 following the inbstructions from : Installing ROOT - ROOT

When I launch ROOT with command root, I get :

root

Invoking:

Do the RBrowser does not work for ubuntu 21 or is there something I miss ?

Please read tips for efficient and successful posting and posting code

ROOT Version: 6.26.00
Platform: ubuntu 21.10
Compiler: gcc 11

You are trying to use binaries that were built on Ubuntu 20.04 / gcc 9 on Ubuntu 21.10 / gcc 11.

3

ok, so do you think it will be more useful to load sources and make a compilation or will I have to wait a version which will be compiled for my configuration ?

4

If you want “native” binaries for Ubuntu 21.10 / gcc 11, then you need to “build from source”.

Ubuntu 22.04 LTS is coming soon, so building “official” ROOT binaries for your “almost outdated” release does not make sense.

5

You can also use the conda or snap package (see Installing ROOT - ROOT ) instead of compiling from source.

Cheers,
Enrico

P.S. I also tried the installation from sources with :

gmake[1]: *** [CMakeFiles/Makefile2:37151 : roofit/hs3/CMakeFiles/G__RooFitHS3.dir/all] Erreur 2
gmake: *** [Makefile:171 : all] Erreur 2

and with : cmake -DCMAKE_INSTALL_PREFIX=~/Téléchargements/ROOT/root_6.26.00 ~/Téléchargements/ROOT/root_src -Droofit=OFF
I get :
