OpenScad 2014.03 - Segmentation Fault
Hi!
I developed this model (https://github.com/speendo/tapeholder) in several
months ago in some older version of OpenSCAD.
Now I made a test print and wanted to make some corrections. My Debian
Stretch x64 system(s) updated OpenSCAD to version 2015.03. The new user
interface looks beatiful, but - while already a bit slow in previous
versions - the model is really not usable anymore in the new version of
OpenSCAD.
I read that the laggy model viewer is some kind of Qt 5 problem that comes
with complex models (well, I didn't find my model that complex, but my
computers have a different opinion, obviously) in version 2015.03 and cannot
be solved. Therefore I tried to downgrade to version 2014.03 by downloading
the binaries from http://www.openscad.org/downloads.html.
That worked on my netbook - the model is still laggy but it's possible to
work with it. On my desktop computer which has 2 monitors I didn't succeed.
When I try to run OpenSCAD from the console I get a "Speicherzugriffsfehler"
which translate from German as "Segmentation Fault" (at least I think so).
What can I do now? I would like to edit my model in a not too old version of
OpenSCAD. Version 2015.03 seems to be unusable and version 2014.03 does not
even start :-(
Can you help me to make one version work?
Thank you in advance!
Marcel

Maybe try the snapshot builds that are still built against Qt4.
The package is called openscad-nightly so it can be installed in parallel
to the normal repository version.
The Debian8 version works on Debian/testing too (that's how I use it).
Unfortunately OBS will not support Stretch until it's officially released.
See http://www.openscad.org/downloads.html#snapshots
ciao,
Torsten.
The laggy UI behaviour appears to be a problem when using some version of the X11 port of Qt5.
Do we know what the cause of this problem is? Can it be solved by upgrading Qt or are we doing something fishy in the UI code of OpenSCAD itself?
As this question pops up with increasing frequency, it sounds like a good candidate for the FAQ: https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/FAQ

Thank you for your answers!
So I tried to install OpenSCAD 2015.11 on Debian Stretch x64 from the
development snapshots. I didn't succeed because of a missing dependency:
$ sudo aptitude install openscad-nightly
The following NEW packages will be installed:
libboost-filesystem1.55.0{a} libboost-program-options1.55.0{a}
libboost-regex1.55.0{a}
libboost-system1.55.0{a} libboost-thread1.55.0{a} libglew1.10{a}
openscad-nightly{b}
0 packages upgraded, 7 newly installed, 0 to remove and 45 not upgraded.
Need to get 4363 kB of archives. After unpacking 14.8 MB will be used.
The following packages have unmet dependencies:
openscad-nightly : Depends: libcgal10 which is a virtual package.
Depends: libqscintilla2-11 which is a virtual package.
The following actions will resolve these dependencies:
Keep the following packages at their current version:
-
openscad-nightly [Not Installed]
Accept this solution? [Y/n/q/?] n
*** No more solutions available ***
Is there a possibility to solve that issue or do I have any other choices?

Hmm, looks like it still works for me as it did install those dependencies
before and they are still there.
Unfortunately it seems Ubuntu decided to package opencsg with a different
package name in 15.10, so that does not work either :-(.
That should still leave 2 options:
- install those missing dependencies from stable
- build from source following the instructions on github
ciao,
Torsten.
are there packages named qscintilla and cgal that need to be installed?

Yes!
cgal:

Can I use those packages?

How did you do that?
What I meant is basically what's described there (but with different
values):
http://serverfault.com/questions/22414/how-can-i-run-debian-stable-but-install-some-packages-from-testing
I'm running with
testing = 750
stable = 400
unstable = 50
which gives testing the priority but allows to resolve packages from
stable too.
In addition that gives the possibility to specifically override the
selection for some packages, e.g. I tried compiling against an older
version of libglew-dev which is at version 1.13 in testing by:
sudo apt install libglew-dev/stable
which downgrades to 1.10 from stable. This can be reverted by simply
running the install without the "/stable" again to select the
version from testing.
ciao,
Torsten.
