Hi,
this chrash seems to depend on the FC version.

I can reproduce it with:

Code: Select all

OS: Linux Mint 18.3 (X-Cinnamon/cinnamon)
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.19.17499 (Git) AppImage
Build type: Release
Branch: master
Hash: 6b1be38f35686faf21e1015bf562520929890870
Python version: 3.7.3
Qt version: 5.9.7
Coin version: 4.0.0a
OCC version: 7.3.0
Locale: German/Germany (de_DE)

The crash does not happen with Py2/Qt4 builds of FC0.18.1 and FC0.18.3
I will try to investigate what's happening there...

[bzb.dev001]

The issue still occurs with the latest 0.19 build with A2plus 0.4.26a.

I have just moved from Windows to MX Linux and am having trouble with older assembly files that I try to open with A2Plus workbench installed. I have attached a sample file which was created before I had my new installation of FreeCAD on Linux. With A2Plus installed FreeCAD crashes when I try to open this file. This only happens with assemblies - single parts open. Strangely I can also create a new assembly with A2Plus installed.

When I removed A2Plus and installed Assembly 2 it opened the file. I have since added Assembly 4 to my installed workbenches and it opened the file. I also have exploded assembly installed which is working fine.

I can get by with what I have installed (I think) but thought this information might be helpful.

Hi,
opening your file with FC0.18.4 (AppImage) causes a crash on my system too, whereas opening it with recent FC0.19-daily works fine.
Perhaps you should upgrade to FC0.19.

[Laurie Hartley]

Perhaps you should upgrade to FC0.19.

Thanks kbwbe. I would like to but I would need some help as to how to go about that on Linux - Version 19 is not in any of my repos for MX

[Syres]

Version 19 is not in any of my repos for MX

Just for starters though, you can download and make the 0.19 AppImage executable and then give it a try which includes all it's dependencies hence it's name. https://github.com/FreeCAD/FreeCAD/rele ... g/0.19_pre currently FreeCAD_0.19-21514-Linux-Conda_glibc2.12-x86_64.AppImage

I still run both Windows and Linux Mint 19.3 in dual boot, I started in Linux by using the AppImage, progressing onto the Daily build and now I compile as it's reasonably easy but you stay on the AppImage if you feel comfortable using it.

I have since added Assembly 4 to my installed workbenches and it opened the file.
...
Version: 0.18.4.

Please be aware that Assembly4 relies on the App::Link framework introduced with FreeCAD v0.19, therefore you'll not be able to make much use of it with v0.18

[Laurie Hartley]

Syres and Zorko thank you for your responses. I have downloaded the V.19 appimage. Just one question do I have to uninstall my existing 18.4 version of FreeCAD?
