Original report text

Attempting to use OpenSCAD features results in the following error:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/denns/tmp/freecadapp/squashfs-root/usr/Mod/OpenSCAD/importCSG.py", line 105, in insert

  File "/home/denns/tmp/freecadapp/squashfs-root/usr/Mod/OpenSCAD/OpenSCADUtils.py", line 158, in check_output2
    raise OpenSCADError('%s %s\n' % (stdoutd.strip(),stderrd.strip()))
<class 'OpenSCADUtils.OpenSCADError'>: " /usr/bin/openscad: /home/denns/tmp/freecadapp/squashfs-root/usr/lib/libQt5Core.so.5: version `Qt_5.14' not found (required by /usr/bin/openscad)\n/usr/bin/openscad: /home/denns/tmp/freecadapp/squashfs-root/usr/lib/libQt5Core.so.5: version `Qt_5.13' not found (required by /usr/lib/libqscintilla2_qt5.so.15)\n"

This is caused by a mismatch between the version of QT in the AppImage and the version used by OpenSCAD (outside of the AppImage). It can be fixed by unsetting LD_LIBRARY_PATH in prior to calling OpenSCAD.

What's blocking is a missing openscad package on conda. Anyone willing to create one?

[luzpaz]

is there an openscad conda feedstock?

[looooo]

@luzpaz no I don't think so.

[luzpaz]

@looooo If there was an OpenSCAD feedstock...would we be able to use it from a License point of view? (SInce AFAIU OpenSCAD is GPLv3)

Edit: https://github.com/openscad/openscad/blob/master/COPYING

[looooo]

We already have gpl3 packages bundled. So why not.

Forums user "lamikr" has submitted a patch to address this: https://forum.freecadweb.org/viewtopic.php?p=609157#p609157

I'm attaching the patch here: I'll turn it into a PR shortly.

Thanks chennes! JFYI, can you keep an eye open for Snap package users who are having issues with OpenSCAD too? Thanks!

Hey Guys,

SOLVED: The fix suggested by lamkr at https://forum.freecadweb.org/viewtopic.php?p=609157 worked for my issue too.

I appologize if this is the wrong place to be posting this. But I'm trying to use the FreeCAD AppImage (FreeCAD-0.20.0-Linux-x86_64.AppImage Revision 29177 (GIT)) in conjunction with the OpenSCAD AppImage (OpenSCAD-2022.05.15.ai11886-x86_64.AppImage) on an Ubuntu 20.04 system with neither app install natively.
The dependency error I am getting is.

<class 'OpenSCADUtils.OpenSCADError'>: ' /usr/bin/AppImageLauncher: /tmp/.mount_FreeCAAP5tZQ/usr/lib/libcurl.so.4: no version information available (required by /usr/bin/../lib/x86_64-linux-gnu/appimagelauncher/libappimageupdate.so)\nqt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""\nThis application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.\n'

I think I have all the related xcb packages installed on my base system, and the OpenSCAD AppImage executes fine by itself.

I'm not sure if this is related to the fix you discuss here or not. Any suggestions would be appreciated, also it's unclear to me if the patch you mention above is available in some kind of nightly build of the FreeCAD AppImage or not. I will try to test some more things and report back here if I find any workaround.

For the record I tried the snap packages too and got a different error about "libQt5Gamepad.so.5" missing and installing the dependency to my root install didn't help.

UPDATE:
Looking at the error above more closely it seems to be saying libcurl.so.4 is missing.
But confirmed I have that installed on my base install too (perhaps it needs to be in the FreeCAD AppImage? or maybe its the LD_LIBRARY_PATH thing mentioned above.)

Do you mind opening a ticket on https://github.com/FreeCAD/FreeCAD-snap/ to report this? TIA!

Yup I can do, I'll try to get to add it in the next week or so.

Can I close this in favor of FreeCAD/FreeCAD#8239 / FreeCAD/FreeCAD#7182
