Dear Community,

I recently installed version 0.14.0 of OpenMC. To install the code, I cloned the official repository using:

$ git clone --recurse-submodules [GitHub - openmc-dev/openmc: OpenMC Monte Carlo Code](https://github.com/openmc-dev/openmc.git)

Then I ran cmake. I made sure to build OpenMC with a debug build:

$ cmake -DCMAKE\_BUILD\_TYPE=Debug …

Following the instructions at [4. Test Suite — OpenMC Documentation](https://docs.openmc.org/en/latest/devguide/tests.html), I set OPENMC\_CROSS\_SECTIONS and OPENMC\_ENDF\_DATA. Unfortunately, I do not have NJOY installed on my machine.

To test the installation, I ran ctest on the “build” folder and pytest on the “tests/regression\_tests” and “tests/unit\_tests” folders. While all the c++ tests and most of the unit tests passed, most of the regression tests, 133 out of 165 to be exact, failed.

Is anyone experiencing the same issues? Do you have any recommendations?

Thank you very much in advance, and compliments once again for the great job you are doing!
