spacenavd not working with blender .. Is this compiled with spacenav support? #18

Closed japrogramer closed 1 year ago

japrogramer commented 6 years ago

hello I am on linux, I run blender from the flathub flatpak like this 

$XAUTHORITY=$HOME/.Xauthority sudo spacenavd -v -d
$flatpak run org.blender.Blender

is it because it runs in a jail that it cant detect the magic sauce that spacenavd is doing

bochecha commented 6 years ago

What if you run Blender with the following command?

$ flatpak run --device=all org.blender.Blender
bochecha commented 6 years ago

Seems another problem is that we build Blender with -DWITH_INPUT_NDOF:BOOL=OFF.

To enable that, we'd have to add the Spacenav libraries to the build.

I'll try to have a go at this.

bochecha commented 6 years ago

@japrogramer Since I don't have the spacenab hardware I can't reproduce the problem or try to debug it.

However, maybe you can help me. :slightly_smiling_face:

I'd like you to do the following, if possible:

  1. uninstall Blender from Flathub:

    $ flatpak uninstall org.blender.Blender

  2. download and install a bundle I just made (from #19) for testing purposes:

    $ wget https://www.daitauha.fr/static/blender.flatpak
$ flatpak install --user blender.flatpak
Installing for user: org.blender.Blender/x86_64/spacenav from bundle blender.flatpak

  3. run the test build:

    $ flatpak run org.blender.Blender//spacenav

Do things work?

japrogramer commented 6 years ago

@bochecha sorry for the late respond everything was sent to spam on my email, so i didn't see it until now. I will try this tommorow in the morning when I am near my hardware.

japrogramer commented 6 years ago

@bochecha finally had the chance to install and run, it didn't work .. I ran the program like you suggested and tha I ran it with all the devices passed like in the first comment

here is everything in my set up

bochecha commented 6 years ago

@japrogramer so you tested it… but then does it actually work? :thinking:

japrogramer commented 6 years ago

@bochecha I mentioned that it didn't work, I should also mention that I'm running Wayland.

bochecha commented 6 years ago

Oh sorry, I missed it.

Did you get any output in the terminal when running Blender? Maybe try with --debug-all? (that might make it extremely verbose)

japrogramer commented 6 years ago

@bochecha i finally got to it, still doesn't work. flatpak run --device=all org.blender.Blender//spacenav --debug-all

Blender quit
Arxcis commented 4 years ago

@bochecha

spacenavd-clients does not listen to the device directly. The spacenavd-events are sent across the X11 socket (for compability with clients written for the closed source driver) and also a Unix domain socket for features only available in the open spacenavd-driver.

Clients that use libspnav, have the option to use either the legacy X11-mode or the Unix socket mode.

According to the https://github.com/FreeSpacenav/spacenavd#dependencies, Blender is utliizing the Unix socket mode.

The path to the Unix socket is defined in 

#define SPNAV_SOCK_PATH "/var/run/spnav.sock"

https://github.com/FreeSpacenav/libspnav/blob/master/spnav.c#L39

Update

The blender source code also confirms this:

#define SPNAV_SOCK_PATH "/var/run/spnav.sock"

GHOST_NDOFManagerUnix::GHOST_NDOFManagerUnix(GHOST_System &sys)
    : GHOST_NDOFManager(sys), m_available(false)
{
  if (access(SPNAV_SOCK_PATH, F_OK) != 0) {
#ifdef DEBUG
    /* annoying for official builds, just adds noise and most people don't own these */
    puts("ndof: spacenavd not found");
    /* This isn't a hard error, just means the user doesn't have a 3D mouse. */
#endif
  }
  else if (spnav_open() != -1) {
    m_available = true;

https://github.com/blender/blender/blob/master/intern/ghost/intern/GHOST_NDOFManagerUnix.cpp#L24-L34

This also explains why we don't see any errors, because the error "ndof: spacenavd not found" is silenced other than in debug-builds.

Arxcis commented 4 years ago

I tried

$ flatpak run --filesystem=/var/run/spnav.sock --user org.blender.Blender//spacenav 
bwrap: Can't make symlink at /var/run: File exists

Does that mean that the socket is available inside the flatpak?

ghost commented 3 years ago

Did anyone figure out how to make it work with blender flatpak?

adrianinsaval commented 2 years ago

posting in case it's relevant, socket path seems to be configurable now: https://github.com/FreeSpacenav/libspnav/releases/tag/v0.3

ananace commented 2 years ago

I added the support into FreeCAD with https://github.com/flathub/org.freecadweb.FreeCAD/pull/55 - the exact same changes should work for Blender as well.

Of course, if your system follows spec with /var/run being a symlink, then something as simple as flatpak override --user org.blender.Blender --filesystem=/run/spnav.sock:ro should be enough.

tkrill commented 1 year ago

@ananace comment solves this for me.

flatpak override --user org.blender.Blender --filesystem=/run/spnav.sock:ro

Could this permission somehow be integrated in the flatpak build?

adrianinsaval commented 1 year ago

I do not have a 3d mouse so I cannot test, those of you who have it please test this PR: https://github.com/flathub/org.blender.Blender/pull/131#issuecomment-1366221802

tkrill commented 1 year ago

@adrianinsaval i downloaded and tested the version with the PR above. Seems to work for me.

Arxcis commented 1 year ago

Thank you very much @adrianinsaval :clap: for implementation and @tkrill for testing :smile: and @kevinsmia1939 for merging :+1:
