Hi Steffen,
Good question :)
I tried installing it with conda because I'm having issues with current installation in a virtual environment (not NEST related issue).

Following were the steps:
conda update conda
    conda create -n nest_conda nomkl numpy scipy matplotlib ipython cython nose
    conda activate nest_dev
    pip install junitparser

and a few other pytest packages. I am certain that it is permission issue but I don't know how to resolve this issue "runtime library [libgomp.so.1] in /usr/lib/gcc/x86_64-linux-gnu/9 may be hidden by files in:  /home/<user>/miniconda3/envs/nestConda/lib" without running CMAKE with sudo

Hi Maryada

Thanks for your feedback.
Could you describe me exactly what you did to install NEST?

Dear NEST users,
After trying multiple ideas, I am still facing the issue where my installation is successful with an error message:

-- Configuring done
CMake Warning at cmake/UseCython.cmake:100 (add_library):
  Cannot generate a safe runtime search path for target pynestkernel because
  files in some directories may conflict with libraries in implicit

    runtime library [libgomp.so.1] in /usr/lib/gcc/x86_64-linux-gnu/9 may be hidden by files in:

  Some of these libraries may not be found correctly.
Call Stack (most recent call first):
  cmake/UseCython.cmake:283 (python_add_module)
  pynest/CMakeLists.txt:28 (cython_add_module)

This leads to the failure of multiple tests. The summary of the tests and logs for the failed tests is attached.

I must mention that I tested the installation by creating a neuron and it works fine.

It would be nice to get rid of the error,  please see error_msg file to see where it fails.

Thanks and Regards
