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?

Best
Steffen

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
  directories:

    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

  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.
