OpenSCAD for Raspbian ??
Is there an up to date prebuilt package for OpenSCAD to run under
Raspbian ??
If so, where can I get it ?
I found one that runs OK but it is rather old :-(
TIA
Dave
I have seen there already is a travis yaml file, I could try to port
it to Shippable to build it on their ARMHF and AARCH64 machines...

I understand that the Rpi only supports OpenGL ES, which is not sufficient
for OpenSCAD which needs full OpenGL, I have a vague recollection of a build
without preview that could do command line rendering, but that was a while
ago.
Admin - email* me if you need anything, or if I've done something stupid...

Raspberry pi 4 with raspbian supports opengl 2.1 using mesa and x11. AFAIK openscad should compile and run without any changes, with the standard Raspian install. I need to get a pi 4 so I can test this.
X11+OpenGL is also available on Raspberry Pi 3, if you are running an up to date version of Raspian. The original Pi 3 version of Raspian didn't support this. AFAIK, OpenSCAD should work. Haven't tested it.
Earlier pi models had a nonstandard opengl es library interface that bypassed x11 and wrote directly to the display (so, without a window manager). Unless there is a Qt port to that older API, openscad isn't compatible.

I just built it on a aarch64 Debian buster machine.
Is there anything else to grab except the openscad binary?
openscad: ELF 64-bit LSB pie executable, ARM aarch64, version 1
(GNU/Linux), dynamically linked, interpreter
/lib/ld-linux-aarch64.so.1, for GNU/Linux 3.7.0,
BuildID[sha1]=fe58df40cd15a51668f8964a2bcbfeac43a277d9, not stripped
Thanks.

That depends on what you are going to do. If it's supposed to
be distributable, the best option is likely an AppImage which
collects everything needed in a single file.
As for ARM in general, it's unfortunately not that simple.
Like people already said, OpenSCAD is not able to use GLES.
However that does not so much depend on what the GPU can
do. OpenSCAD happily runs with Mesa software renderer on
a Raspi3. The main question is how Qt is compiled. Usually ARM7
(or 32bit in general) systems enable GLES for Qt so compilation
will fail. Some AARCH64 systems use OpenGL instead, so it's
trivial to compile OpenSCAD.
Some time ago I started setting things up as docker build
using qemu-static but that's a bit annoying and quite slow.
I did have a working AppImage at some point, but it still
needed too much manual interaction to build.
It might be possible to set this up on OBS, but so far I
had too much trouble building AppImages there so I gave up.
Getting this to work would be great as OBS is very nice
in general.
ciao,
Torsten.
I know nothing about AppImage, but will try to find how to build one
for OpenSCAD.

The x86_64 build is handled via base docker image collecting all
the tooling:
https://github.com/openscad/docker-openscad/blob/master/appimage/appimage-x86_64-base/Dockerfile
and the actual build via:

Very interesting, thanks Torsten.
I will try to port it to aarch64.

Cool. Could you please disable the IRC notifications in the
travis.yml? It's currently reporting all build error :-).
ciao,
Torsten.
