error while loading shared libraries libImt.so

[fpbarthel]

I'm trying to run cnvnator which requires ROOT, so I installed it using conda from the NLeSC channel. However, it doesn't locate the right libraries, and running CNVnator results in the following error:

error while loading shared libraries: libImt.so: cannot open shared object file: No such file or directory

Is this a version issue?

The NLeSC ROOT Conda package is no longer maintained and does not work properly with current Conda, modern Python, or modern ROOT. Use conda-forge ROOT instead:

Installing in a new environment:

conda create -n myrootenv python=3.7 root -c conda-forge
conda activate myrootenv
conda config --env --add channels conda-forge

From then on, use conda activate myrootenv to get in and conda deactivate to get out of the env. You should have a recent version of conda.

or

Installing in the current environment:

conda config --env --add channels conda-forge 
conda install root

Unlike the NLeSC package, this can even be the base environment if you really want to do that (it is not ideal, since it will be rather invasive, adding things like conda's compiler packages that are needed to compile with ROOT and Conda).

Conda-forge ROOT provides ROOT 6.16.00+, and supports Python 3.7, 3.6, and 2.7 on macOS and Linux. It is being tested by the ROOT team, and is automatically build by the conda-forge infrastructure. All default features and a huge number of optional features are turned on, and you can use it anywhere you would use ROOT, JupyROOT, or PyROOT.
