Arch Linux User Repository

Flatcam no longer works with the current numpy version it seems. Running it in the terminal yields

ImportError: cannot import name 'Inf' from 'numpy' (/usr/lib/python3.12/site-packages/numpy/init.py). Did you mean: 'inf'?

Missing dependency "python-darkdetect", also the launcher script tries to launch /opt/flatcam-qt6/FlatCam.py which doesn't exist. Instead need to run /opt/flatcam-qt6/flatcam.py, which is lacking executable permission.

Current python-or-tools from AUR does not build for me.

Today it is need add 'python-pyserial', 'python-pyqtdarktheme' to dependencies. FlatCAM started up and works well. I didn't have to change anything in the py code.

Note: For me some of dependency packages has not built for today. As example 'python-or-toools' and 'python-svg.path'. (First can be built success as version 9.5 (from aur snapshot); second can be built with delete of 'check()' in PKGBUILD.) On a clean system, no more fixes were needed.

For anyone that just wants this package working here's what works for me on Arch/ Manjaro:

$ git clone https://github.com/vispy/vispy.git $ cd vispy $ pip install -e . --break-system-packages

(The above is required because vispy also fails to build from Pamac)

$ pip3 install darkdetect --break-system-packages $ pip3 install svg.path --break-system-packages

Install in Pamac, but click "edit build files". Leave everything as they are for python-vispy, etc but when you get to the files for flatcam-qt6 comment out all the dependencies. Apply/ build and wait for install.

Once installed, go into /opt or wherever it installed to and find appMain.py. Comment out these lines (around line 50):

import qdarktheme

import qdarktheme.themes.dark.stylesheet as qdarksheet

import qdarktheme.themes.light.stylesheet as qlightsheet

Then find appMain.py and comment out these lines (around 625):

if self.options["global_theme"] == 'default':

self.resource_location = 'assets/resources'

elif self.options["global_theme"] == 'light':

self.resource_location = 'assets/resources'

qlightsheet.STYLE_SHEET = light_style_sheet.L_STYLE_SHEET

self.qapp.setStyleSheet(qdarktheme.load_stylesheet('light'))

else:

self.resource_location = 'assets/resources/dark_resources'

qdarksheet.STYLE_SHEET = dark_style_sheet.D_STYLE_SHEET

self.qapp.setStyleSheet(qdarktheme.load_stylesheet())

NOTICE THE SECOND LINE IS NOT COMMENTED OUT AND IS DEDENTED

Next find MainGUI.py and replace the following line (2098 at time of writing):

self.splitter.setSizes([splitter_left, 0])

with

self.splitter.setSizes([int(splitter_left), 0])

Lastly rename flatcam.py to FlatCAM.py and you should be able to run with

$ python3 FlatCAM.py

and make desktop shortcuts or whatever you want to do

Hope that saves someone the time I spent to figure it all out

On a fresh system install I found I was missing python-pyserial, this should be added as a dependency.

Start of flatcam-qt6 failed

Traceback (most recent call last):

If somebody install additional package with pip install pyqtdarktheme next error will arise:

Traceback (most recent call last):
  File "/opt/flatcam-qt6/FlatCAM.py", line 8, in <module>

This package is only used when you want to change theme. So flatcam will work when you delete code with qdarktheme You can comment lines that "contains" qdarktheme and run it without any problem.

You can "fix it" by editing /opt/flatcam-qt6/appMain.py with sudo!

Lines that I have commented:

43 #import qdarktheme
44 #import qdarktheme.themes.dark.stylesheet as qdarksheet
45 #import qdarktheme.themes.light.stylesheet as qlightsheet

642         #elif self.options["global_theme"] == 'light':
643         #    self.resource_location = 'assets/resources'
644         #    qlightsheet.STYLE_SHEET = light_style_sheet.L_STYLE_SHEET
645         #    self.qapp.setStyleSheet(qdarktheme.load_stylesheet('light'))
646         #else:
647         #    self.resource_location = 'assets/resources/dark_resources'
648         #    qdarksheet.STYLE_SHEET = dark_style_sheet.D_STYLE_SHEET
649         #    self.qapp.setStyleSheet(qdarktheme.load_stylesheet())

BTW, this is not ideal way to fix this, but it works.

So I assume I have to install an additional package...

I had to install python-darkdetect from the community repo to be able to launch flatcam after a new install.

qdarktheme is not resolved. install pyqtdarktheme via pip to solve it. Careful, there is a "t" in there. For some unknown reason though, even with that installed and before you get into the gui, I got this:

/usr/bin/flatcam-qt6: line 3: 182195 Segmentation fault (core dumped) python /opt/flatcam-qt6/FlatCAM.py $@

Took like an hour to compile, so I gave up and moved to another version.

Fixed the missing dependency. Through the .install file of makepkg, that installs the dependency via the python's pip
