Install on macOS from CONDA

I installed OpenMC on my MAC (INL issued). Conda/Mamba complete their process. OpenMC is installed. I ran JEZEBEL.PY and also a couple of other files that I created. OpenMC runs fine. It creates all the required xml. Results appear good.

I am having trouble with plotting packages:

I tried openmc --plot
error is: “Application built with libpng-1.4.12 but running with 1.6.43”.

I then installed opened-plotter
it worked yesterday. but today it is not. Here is the message I get:

can someone help me. INL experts (Michal and Travis) are at PHYSOR. I need to get work done

Hi, did you solve the problem by any chance ? It happens the same to me…

3

Nope. But there is a similar string under a different topic. They identified some solutions for linux and ubuntu etc. You should check that. I liked the plot package but it is a bummer. Let me know if you find some fix.

Could you please tell me the string / topic title you’re referring to ? So it will be easier to find what you told me. I’ll let you know if I find different solutions.

On this same site under user support there is an item “OpenMc plotter aborts when ……” Hope that helps

I’ve been getting the same error (“Application built with libpng-1.4.12 but running with 1.6.43” followed by a seg fault) on an Apple Silicon MacBook, running in a Rosetta Terminal). First blush suggests to me that it is an old version of OpenMC in the conda-forge repository. But, doing a little research, libpng-1.4.12 is really old. Old enough that I haven’t been able to find a repo for it and leading me to suspect it is a different problem pretending to be a dependency problem.

It would be really awesome if we could get arm64 versions of OpenMC from conda-forge. I’m currently working on setting up a conda environment to do a arm64 compile from scratch. (My build and install fu is really out of date, so I’m having to do a lot of re-education.)

Jeff this is DV Rao. If you ever finish this project and have a MACbook version on Conda let me know.

I see that conda-forge has a useful blog post on ARM support if you are keen to put in a PR to the openmc-feedstock repository that would be great. I see that there are also Snapdragon ARM based CPU heading to Windows laptops soon so I think this ARM support is going to be a growing request.

Shimwell
I’m a dinosaur of 20th century… so am a heavy user but not well versed with Python and Conda. I like OpenMC and am using it on my MacBook (which is currently beating many of the clusters I have access to). Anyone who can post a version that gets rid of plotter issues would be great.

Will do, though there is a lot of figuring out to do on my part. I’m running into linker errors when trying to recompile, so that’s interesting. I’m so out of date!

I think I have put in the PR to create an arm64 version. Waiting on approval.
