[SOLVED] Segfaullt in Invesalius3 Mint-19.0

business_kid · 01-09-2019, 09:00 AM

Hi
It's a fairly fresh install of Mint-19.0, duly updated & upgraded. Invesalius-3.1.1 is installed with synaptic. I did also try the debian .deb, but that seemed to behave the same (segfault). Here's the terminal output:

Code:

invesalius3
/usr/share/invesalius/invesalius/data/transformations.py:1899: UserWarning: failed to import module _transformations
  warnings.warn("failed to import module %s" % name)
session mode:  0

(app.py:1709): Gtk-CRITICAL **: 14:43:28.906: gtk_widget_set_size_request: assertion 'width >= -1' failed
Segmentation fault

That probably means something to someone who speaks python-ese, which I don't. I'm strictly a hardware head - obsolete hardware, for the most part. I get the above 3-4 seconds after launch. I have /usr/share/invesalius/app.py but it's 384 lines.

You may want to look through the bug reports (both open and closed) here - https://github.com/invesalius/invesalius3/issues - and create a new issue if yours hasn't already been reported.

Thanks Hydruga. I installed Mint instead of LFS as my spare system. There's a FIXME about W64 in app.py - apparently it trips over the language setting. It's on to to-do list to find a virtualbox vm containing Mac OSX or higher.

EDIT: Also filed a bug now with the Invesalius Devs.

I think I read somewhere in those links that the developer says that the software should work ok under a KDE/Qt environment. You might have some joy creating a Kubuntu virtual machine, or similar, to run it. Mint 18.3 KDE if you prefer.

Qt5 is in Mint. I added python3, since it is a python thing. I can't do KDE in my host system, let alone in a guest. My limit there is 6G of ram, with half minimum going to the host system. I more or less have myself sorted without Invesalius, or exotic OSes. But I did confirm the Ubuntu bug, and post one in the Invesalius setup. https://github.com/invesalius/invesalius3/issues/161

He's back very quick with something to try. I'll have to boot Mint (again!) and try that. Manyana…

Out of interest, bk, what do you mean by "you added python3"? Python 3 comes as standard in Mint (and in fact is required for a fair chunk of Mint functionality).

6GB of total RAM is perfectly sufficient to run a VM with a KDE-supporting distro (I too have 6GB and dedicate 2GB to each of my virtual machines when I want to run them). You won't need to be running the VM all the time anyway, you only need to fire it up when you need to use Invesalius.

When I asked it to install python3, it installed stuff. I didn't look what.

Updating to the latest Invesalius in the PPA solved it. Invesalius isn't bad.

Nice one.
