Description
I have a 3dconnexion space navigator. Current drivers are version 1.1.4.
When the commnad "device snav on" is issue the following error is reported:
Could not start space navigator. cannot import name '_spacenavigator' from 'chimerax.spacenavigator' (/Applications/ChimeraX-0.93.app/Contents/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/chimerax/spacenavigator/__init__.py)

Thanks, keep up the good work.

The problem is that the Space Navigator library is not installed on our Mac ChimeraX build machine essex.cgl.ucsf.edu. I am not able to log into that machine, possibly I don't have an account on it.

Eric I think essex is your development machine. Could you install the Space Navigator driver (called "3DxWare 10 for macOS") on essex?

​https://www.3dconnexion.com/service/drivers.html

Once that is installed then the _spacenavigator module will get compiled and the device may then work in the daily build.

I tested Space Navigator on Windows 10 in ChimeraX and Chimera, both working. I was unable to get macOS 10.15.4 (Catalina) to even recognize device -- it will only treat it as a mouse, the Space Navigator control panel says no device connected. This is on a 2019 MacBook Pro with only USBC ports and my Space Navigator is old USBA, so the problem could be the USBA to USBC adapter I am using. The reporter is using macOS 10.14 -- let's see if it works there.

I got space navigator to work on my Mac laptop (10.15.4). It required uninstalling and reinstalling the space navigator driver. So I suspect once Eric puts the driver on the build machine the daily builds will work with Space Navigator.

Well, it's a little tricky since the installer is a .pkg and I'm working remotely. Following the guidelines from this page: ​https://apple.stackexchange.com/questions/72226/installing-pkg-with-terminal/72227 I ran the 'installer' command, which seemed to work:

essex:/Users/pett/rm<3> sudo installer -pkg Install\ 3Dconnexion\ software.pkg -target /
Password:
installer: Package name is 3Dconnexion Software
installer: Installing at base path /
installer: The install was successful.
installer: The install requires restarting now.

The question is, do you think I _really_ need to restart? I clearly would if I were _using_ a Space Navigator, but if I'm just linking against the library...

[goddard@…]

I do not think a restart is needed.  I believe it wants to restart because it installs a kernel module.  ChimeraX compilation does not need that -- it only needs the headers and library in /Library/Frameworks/3dconnexion.

[acheron24@…]

I don't know. But I don't mind testing the build without reboot.

The Mac ChimeraX build failed last night (Apple notarization issue) so the space navigator support won't be ready to try until tomorrow's build.

[acheron24@…]

That sounds great.

Mac build failed again last night with Apple notarization problems.  Look for build dated newer than May 11 on downloads page before testing space navigator.

[Tom Goddard]

Fixed.

Tested today's mac build and space navigator worked.

[acheron24@…]

I can confirm, great work.

Thank you very much.
