FEM and python 3 issues

[triplus]

wow that sounds gread! but I need to install some package on my debian, do I? Which one, there is no package called appimage on debian stretch.

No additional packages need to get installed. What is needed is already included in the AppImage. As @sgrogan pointed out therefore all you need to do is to download the AppImage from the FreeCAD GitHub releases page (and follow the procedure above).

P.S. Note that there are 2 AppImages on the releases page (Py2/Qt4 - PPA based and Py3/Qt5 - Conda based).

FYI there is a Conda based AppImage available and therefore you don't need Windows to test it.

Is there a way to edit files (.py) in the AppImage? Testing is great, but we are counting on bernd to fix it.

Sure.

Code: Select all

downloaded.AppImage --appimage-extract
cd squashfs-root

You can navigate to content such as usr/Mod/Fem/module.py and do some modifications. To test the changes:

Code: Select all

./AppRun

If you want to pack it again as an AppImage:

Code: Select all

cd ..
wget "https://github.com/AppImage/AppImageKit/releases/download/continuous/appimagetool-x86_64.AppImage"
chmod a+x appimagetool-x86_64.AppImage
./appimagetool-x86_64.AppImage squashfs-root

I never knew it's so easy ... i really could'nt believe it

[bernd]

- start FreeCAD
- open FEM new solver example
- double click on elmer solver

Code: Select all

Good to hear it is working. Thanks to all the hard work AppImage inventors did. Packaging work invested on PPA/Conda side. Travis related work macOS FreeCAD packaging team did in the past ...

PR or it didn't happen.

Mentioned procedure doesn't modify your environment in any way. That is nothing gets installed and no environment paths get modified.

FYI, I've added this to Appimage#Using_AppImages_in_your_Development_Workflow

[triplus]

Great.

if the PR would be the one that counts I have joined month ago already ... git commit 42bfdf2 or git commit 8de9707 or git commit 656a669 IMHO joining the party for me means MY work and developing machine runs Py3 ...

All this Python 3 partying going on lately. Hard to keep track!
