Installing on Apple MacBook M4

[konerr]

Hello,

I have not been able to install Bluemira on my new M4 series MacBook and was wondering if anyone had better luck than me.

Due to trouble installing openmc on arm64, I switched to osx-64 using rosetta and was able to install openmc. However, I am now stuck with the following FreeCADGui import error when I try to run examples/equilibria/eudemo_2017.ex.py
Error:
import FreeCADGui as Gui
ImportError: dlopen(/Users/rahul/miniforge3/envs/bluemira1/lib/FreeCADGui.so, 0x0002): Symbol not found: __Z12qt_blurImageP8QPainterR6QImagedbbi

I understand this is a FreeCADGui issue but wanted to see if anyone has any ideas.

Configuration

• Chip: Apple M4
• OS: Sequoia 15.5
• Python 3.11.13

Thanks,
Rahul

Hi Rahul,

We're having the same problems at the moment and have for a while, we have manged to get bluemira installed on an m-series mac before with rosetta but that was pre freecad v1 IIRC.

I've been trying to get any sort of mac runner (arm or x86-64) going with our actions since October (#3512). I had another look this morning and had the same error. My current guess is that freecad have built their conda macos binaries against a specific qt and therefore pyside version that is not dynamically linked or that for some reason qt 5 and 6 are being pulled into the conda env and freecad is linking against the wrong one on macos.

I can get access to a mac (I think its an m1 or m2) to dig directly but I have no timescale on how long that would take. Alternatives I can see, none of which are great:

1. Create a linux VM, I've not tried an arm linux install of bluemira or tried to install an x86 vm on arm (if that is even possible)
2. Manually build freecad on rosetta - I would try and install most of the deps using conda. The freecad conda feedstock is probably a good starting point.

Sorry thats not a very satisfactory answer. I'll update this thread if I make any progress.

@je-cook ,

Thanks for the response. I had some free time last week and I was able to get it to work on a x86 docker image running a amd64 linux. This was quite an experience. I have also noticed that it doesn't install on linux arm or osx-x86 either. I will try building freecad from source on rosetta but the dependency list is turning me off. I'll update the tread if I make any progress.

Thanks again.
Rahul
