 Posted: Thu Jan 03, 2019 4:15 pm Post subject: No pyside in portage |
 |
|
Hi.
For the last year and a half or so, I had been trying to get FreeCAD installed and working on my Gentoo system. It never really worked. I hadn't tried for a while until recently again, and I see that it has been removed entirely from Portage.
Fortunately, I found that FreeCAD offers a stand-alone appimage version. This seems to work just fine under Gentoo -- except when I need to use the Assembly module... as soon as I go to import something, it blows up. I think that this is probably because I do not have pyside installed. But -- it looks like pyside is no longer in portage either. Of course, it is just a guess, but the README pulled from github states that this is a dependency of the module, so I think it is a good guess...
I'm trying to follow the tutorial for creating the lego block, on the freecad website, which introduces the assembly module (something I will need). When I click on "Import a part from another freecad document", it segfaults.

So, I'm wondering if there is a gentoo-sanctioned option for installing pyside (though I doubt it), and failing that, what is the best way to install it? I don't really have any experience with pyside, so I'm at a loss, and I don't want to contaminate my system by installing something that cannot be (at the very least) cleanly uninstalled. Any advice here?
I'm using freecad 0.17.
Thanks.

pyside is qt4 and since qt4 was depreciated it has gone.
Also python got a promotion within the Qt project and as such it is no longer a 2nd class citizen https://wiki.qt.io/Qt_for_Python

That looks like the Qt overlay, which would explain why you don't see it if you don't have said overlay set up. :]

Yes, that was why they dropped FreeCAD from portage... the QT4 thing...
But I do have QT for Python installed... but either it won't cut it, or it cannot find it.
I appreciate what you are saying Chitoo, but I did not want to get into overlays... it just creates headaches at upgrade time. I try to keep my system as pure as possible. I rely on my system too much and just don't have the time to to get into a dependency nightmare these days. Besides, if I did that, I might as well just do the whole FreeCAD overlay (since I'd be in the neighborhood).
I know they are working on a native assembly workbench in FreeCAD... maybe I'll give it a little more time. If I get impatient... I'll try the overlay.
Thanks.

I've been building freecad from git for some years now. But I can't say anything about the assembly module.
I've been using the waebbl overlay for pyside, pivy, pyside-tools, shiboken, opencascade, SoQt, coin, and simage. Waebbl also has freecad packages for stable and development. I've just stuck with building from git source. Freecad will run from its build directroy just fine, but I'd definitely use separate source and build directories. And I haven't had any conflicts come from it.
Unfortunately, both the shiboken and pyside packages are failing to build at the moment, which is what lead me to this thread.
Freecad builds and runs just fine now with QT5.
But you'll need several things from overlays, or install them yourself to get freecad built and running. And you really will want a modern version.
