Cannot open shared object file libssl.so.1.1

[SergeyAmirkhanyan]

When I running root it runs normally. I mean that there appears string root [0]. But upper of this string there are message:

cling::DynamicLibraryManager::loadLibrary(): libssl.so.1.1: cannot open shared object file: No such file or directory

What should be done to solve this problem ?

This problem usually happens when you try to use a ROOT binary distribution that is unsuitable for your operating system.

What problems it can lead to ?

[Wile_E_Coyote]

Expect any problems you can imagine. Usually, it renders ROOT unusable.

I am using 6.26/04 version of ROOT. My Ubuntu version is 22.04. What should I do to solve the problem ?

[Wile_E_Coyote]

The ROOT Team provides ready-to-use binary distributions for some systems (see “Download a pre-compiled binary distribution” therein), including various Ubuntu versions, which you just need to download and unpack.

For Ubuntu 22.04 / x86_64 / gcc 11.2: https://root.cern/download/?C=M;O=A;P=*[uU][bB][uU][nN][tT][uU]*22*

And there is no necessity to reinstal something ?

for the required packages see
Dependencies - ROOT

@smgrig These dependencies are valid when you want to build ROOT from the source.

Unfortunately, there exist no lists of system packages (compilers and libraries) that are needed for the “.tar.gz” binary distributions provided by the ROOT Team . See:

Python and ROOT when installing in WSL / Ubuntu

After unpacking a ready-to-use binary distribution (i.e., compiled by somebody else), I first install all missing libraries reported by (ignore several possible “not a dynamic executable” messages): source /where/I/unpacked/my/new/root/bin/thisroot.sh ldd ${ROOTSYS}/lib/*.so | grep "found" | sort -u On a Debian-like system (e.g., Ubuntu), one can then use “apt-file” to find, e.g., the missing “libgsl.so.23”: sudo apt-get install apt-file; sudo apt-file update # needed just once apt-file searc…

Problems in compiling 6.19/6.20 on Ubuntu 20.04

@amadio This post is more than 5 years old but the problem is “known” for more than 10 years (when Ubuntu 10.04 LTS started to provide its own ROOT version): Actually, with ROOT 6 the “problem” became more serious. Because ROOT 6 versions with “cxx11”, “cxx14” and especially “cxx17” are incompatible with one another (and some features will be incompatible with additional, experiment / analysis specific, software), one needs 3 sets of binaries for each ROOT 6 version so, something like 9 = 3 x…

I just want to understand should I reinstall full program since zero, or I can just delete all files from
root-src folder and just unpack there files from root_v6.26.04.Linux-ubuntu22-x86_64-gcc11.2.tar.gz without any reinstallations ?
