Libstdc++.so: version `GLIBCXX_3.4.30' not found after building from source on Ubuntu

ROOT
1

Hello,

I followed the instructions to build root from source on an ubuntu machine:

git clone --branch latest-stable --depth=1 GitHub - root-project/root: The official repository for ROOT: analyzing, storing and visualizing big data, scientifically root_src
mkdir root_build root_install && cd root_build
cmake -DCMAKE_INSTALL_PREFIX=…/root_install …/root_src
cmake --build . – install -j4
source …/root_install/bin/thisroot.sh

and then when I try to use ROOT in python I hit this error:

python3
Python 3.10.14 (main, Mar 21 2024, 16:24:04) [GCC 11.2.0] on linux
Type “help”, “copyright”, “credits” or “license” for more information.

import ROOT
Fatal in TROOT::InitInterpreter: cannot load library /home/ubuntu/miniconda3/lib/python3.10/lib-dynload/…/…/libstdc++.so: version `GLIBCXX_3.4.30’ not found (required by /home/ubuntu/root_install/lib/libRIO.so)

Is it obvious to someone how to resolve this issue?

Thanks,

Mark

ok, it seems the issue is I am in a conda base shell. If I deactivate that, then importing ROOT works.

So presumably I need to update the libstdc++ version inside my conda shell such that I can use ROOT inside that.

Cheers,

Mark
