FreeCAD and Raspberry Pi 4

[clicky]

Top of 0.18 branch is better - it happily opens documents saved by version from top of the master branch.
(I believe that's version 0.18.3 and a bit)

[kkremitzki]

The current stable tag is 0.18.3 so you can just check that out with git and build it.

if no warnings messages (see my previous post above, maybe I did something wrong or some libs are still missing, or ...?).

For Qt4 there should be a PySide and shiboken package that offer Python modules that can be imported at runtime. When installing them the warning should go away.
Without these modules the Tux wb doesn't load and the Path and FEM wb don't work 100% either.

Ok, however I had installed Pyside libs already:

pi@raspberrypi:~ $ 

it seems to me that Pyside lib for Qt4-Py3 binding is installed, Shiboken py3 as well. Is there something else needed which is missing?

[-alex-]

...Thank you for all your effort. It is working now for me, too. I did what you said (and got to the same state with PySide errors, etc).

Hi Clicky, thanks for your comments and your feedback. I have seen your post on the raspberry's forum: thanks for your reporting overthere
If you expect a full experience with Freecad maybe you should compile with Py2/Qt4 build because of Pyside missing module error with Py3/Qt4 one (at least for now).
I'm trying to solve this trouble right now, but no success.

Hello All,

Hereby I can confirm a successful build on the Pi4. I used the source of 0.18.3. As far as I can see everything is working.

Here is my short list used for installing:

Code: Select all

sudo apt install cmake build-essential libtool lsb-release swig libboost-dev libboost-date-time-dev libboost-filesystem-dev libboost-graph-dev libboost-iostreams-dev libboost-program-options-dev libboost-python-dev libboost-regex-dev libboost-serialization-dev libboost-signals-dev libboost-thread-dev libcoin-dev libeigen3-dev libgts-bin libgts-dev libkdtree++-dev libmedc-dev libopencv-dev libproj-dev libvtk6-dev libx11-dev libxerces-c-dev libzipios++-dev qt4-dev-tools libqt4-dev libqt4-opengl-dev libqtwebkit-dev libshiboken-dev libpyside-dev pyside-tools python-dev python-matplotlib python-pivy python-ply python-pyside libocct*-dev occt-draw libsimage-dev doxygen libcoin-doc dh-exec libspnav-dev

wget https://github.com/FreeCAD/FreeCAD/archive/0.18.3.zip

unzip 0.18.3.zip

mkdir freecad-build

cd freecad-build

cmake -DPYTHON_EXECUTABLE=/usr/bin/python2.7 \ -DPYTHON_INCLUDE_DIR=/usr/include/python2.7m \ -DPYTHON_LIBRARY=/usr/lib/arm-linux-gnueabihf/libpython2.7m.so \ -DPYTHON_PACKAGES_PATH=/usr/local/lib/python2.7/dist-packages/  ../freecad-source
make -j4

Hope it helps someone.

Best regards and keep up the good work!
Martijn

Thanks you very much

Hello everyone,
Thank you all for a solution for using freecad on RPI4.
I was able to install version 0.18 and 0.19 to do tests with my 3D printer. It works perfectly and surprisingly quickly.
I also install the Cura 4.2 slicer (https://www.dropbox.com/sh/s43vqzmi4d2b ... urm4a?dl=0) .
Maybe we will find a solution to switch to python 3 and Qt5, it will be Christmas before Christmas ?
Thanks again to everyone

You are welcome

I am not complaining and almost everything (I know how to use ) is working now. So far only exporting as .obj had an issue - but, that's just really strange requirement I have and I can easily find several work-arounds.

...So far only exporting as .obj had an issue - but, that's just really strange requirement I have and I can easily find several work-arounds.

You should report your problem. As I remember recently some developers made changes to the Wavefront OBJ exporter, so if it fails for you, there is a chance of correcting the issue.

Hey chaps,

I am trying to run FreeCAD on a Pinebook Pro. The precompiled version it will launch but then segfault when I try to open a file.
Now I tried to compile 1.8.4 using MartijnD's instructions. At 45% I get

[ 45%] Linking CXX shared library ../../../../Mod/Mesh/Mesh.so
[ 45%] Built target Mesh
make: *** [Makefile:130: all] Error 2

Any idea what I might be doing wrong? Or is the Pinebook Pro too far away from the RPi4 hardwarewise?

Thanks!
Björn

Unfortunately this snippet doesn't contain the actual error, you'll have to scroll up in your build output to find it. This is just saying "make" failed, but "make" was calling commands itself to do the building, and it's the failure of one of those earlier commands that shows what happened.

You can also upload the entire build output to something like https://paste.debian.net/.

No, it isn't. BTW I ordered one recently so I will be working on getting FreeCAD working on it before too long.

Thanks!
