Creating 3D text causes CQ-editor to segfault #257

Open ornamentist opened 3 years ago

ornamentist commented 3 years ago

I'm running the following script in CQ-editor on a Mac M1 running Big Sur:

#! /usr/bin/env python3

from typing import *
import cadquery as CQ

def assembly() -> Any:
  block = CQ.Workplane("XY").text(txt = "foo", fontsize = 3, distance = 4, cut = False, combine = False, clean = True)
  return block

show_object(assembly())

Unfortunately CQ-editor segfaults when I run this. I could well be doing something wrong here so any advice much appreciated.

I cannot reproduce (though I have no Mac) - can you provide more info on your versions and possible a backtrace?

ornamentist commented 3 years ago

Host: I'm running CQ-editor on an M1 Mac mini with macOS 11.2.3.

Install: CADQuery and the CQ-editor are installed with Miniconda and run using the Miniconda version of Python. Conda list reports:

conda list | grep cad
cadquery                  master                    py3.8    cadquery
cq-editor                 master                    py3.8    cadquery
ocp                       7.5.1beta               1_py3.8    cadquery

Looking in the system logs for a backtrace I get (truncated):

I'm thinking it might be better to run CADQuery and CQ-editor in a container or even a VM, but it would still rely on libraries compiled for an aarch64 architecture.

jmwright commented 3 years ago

To my knowledge you're the first person to try on an M1. I don't think anyone has had any luck on aarch64, and we don't officially support it yet.

ornamentist commented 3 years ago

Fair enough. I'll revisit CQ-editor in the future.

In the meantime big thanks to everyone who works on CADQuery and CQ-editor, they're a great way to access the power of the OpenCascade ecosystem.

greyltc commented 3 years ago

I've built and tested on aarch64. Raspberry pi, not mac though.

This doesn't seem to be native code on the mac though. I see X86-64 (Translated) above. I have no idea how homebrew tries to handle this stuff, but could there be some illegal mixing of native and x86_64 translated architectures going on here?

ornamentist commented 3 years ago

The automated translation of x86 to aarch64 on macOS has worked very well for me so far. Having said that, it could very well be some interaction between the architectures going on deep in the Python and C++ stacks.

fischman commented 3 years ago

On crostini (linux container in chromeos), not OS/X, with cq-editor installed via conda install -c cadquery -c conda-forge cq-editor=master I get a similar stack with:

import cadquery as cq
result = cq.Workplane('XY').text('hello', 10, 2)

The pre-built https://github.com/CadQuery/CQ-editor/releases/download/0.2/CQ-editor-Linux-x86_64.zip works just fine. @adam-urbanczyk points out on discord that the prebuilt has OCCT 7.4.
