Error in `leapd': malloc()

[stormaes]

I'm experiencing a similar problem.
*** Error in `leapd': corrupted double-linked list: 0x00007f7dd4002580 ***
It also occurs when moving hands into and out of tracking.

EDIT:
note: I'm not using a distro built from scratch, but I am using archlinux.
Maybe some newer package version?

archlinux

These errors are most likely related. We only officially support Ubuntu so other distros may have compatibility issues like the one you are experiencing.

I experience similar problems, I am running Ubuntu GNOME 14.04... leapd crashes shortly after booting up but then respawns and seems stable from then on. I attached a summary, I can send the full crash log if it helps:

[jdonald]

I think these crashes are the known corruption issues that have been around since v2.2.7.

Try this build (link updated 2/23/2016) which has several fixes on top of v2.3.1.31549

[jzitelli]

Thanks, haven't had any crashes with that build!

[alexsmith1988]

Hi, is the newer build still available? I'm also having the same problem and that link is dead.

[thiagogcm]

Why does this build not the official one? Any plans for an updated v2 release? or v3 support for Linux. Thanks

[jhung]

It's built off a development branch and hasn't gone through our standard QA. In particular, the change to Qt 5.5 affected a lot of things. Currently all of our resources are driving towards improving the Orion beta, which will eventually have Linux support -- though Android support is first up on the docket.

The links to the patched installer should still be up and running. If anyone runs into any issues with it, please let me know.

[thiagogcm]

Thanks for the prompt reply. Links are up and the patch works (at least for a quick test). Linux support is very welcome but Android is even better. Looking forward to try it!!

[jhung]

Thanks for following up! If you're interested, please keep an eye on developer.leapmotion.com or subscribe to our developer newsletter so you can stay up to date on our releases.

I have this issue too. leapd just survives a couple of seconds before it will exit. This is on Linux Mint 18 Cinnamon 64bit

Hi mns,

Please make sure you are installing the patched installer linked by jdonald above in this thread. You can find it here: https://leapmotion.box.com/s/rlwzvt680i5r6zes75ge36ub2yt7ksx3

[mnx]

This is the output of apt-get:

Errors were encountered while processing:
 leap
E: Sub-process /usr/bin/dpkg returned an error code (1)
A package failed to install.  Trying to recover:
Setting up leap (2.3.1+31549) ...
Leap Motion installed under /usr/bin and /usr/sbin
ln: failed to create symbolic link '/etc/init.d/leapd': File exists
dpkg: error processing package leap (--configure):
 subprocess installed post-installation script returned error exit status 1

I believe this is something your engineers will be able to fix in no time, but will benefit users like myself.

[jdonald]

Looks like the old leap package left something behind. I think when you install a new one it should automatically remove the old one, but just in case it didn't try sudo dpkg --remove leap

If that still leaves /etc/init.d/leapd as a stale file, then that would be due to a bug in the old package. You can force-remove that file via sudo rm -f /etc/init.d/leapd

Then go ahead and try installing the patch and it'll hopefully work or we'll see a different error to troubleshoot next.

[mnx]

After the --remove there is no leapd in /etc/init.d/. But on reinstall this happens:

This would probably take some effort to debug since we don't test or support Mint. We don't really support Debian either, but some changes in the patch to make the installation process amenable to Debian or Ubuntu 15.04 may have broken Mint compatibility further.

Rather than fully fix this, you could just run the daemon manually. After it installs with the error, you can run sudo /sbin/leapd and start the daemon up manually rather than going through systemctl.

[mnx]

Mint 18 is based on Ubuntu Xenial, I don't think it should behave too differently.
Could that be related to the switch from upstart to systemd in Mint 18? Ubuntu switched too, so maybe there is a need to adapt how processes are launched for the leap driver. That's just a guess though.

Hi mnx. Did you solve the problem? I'm having the same error as you . I downloaded the SDK 2.3.1+33747 version from https://leapmotion.box.com/s/rlwzvt680i5r6zes75ge36ub2yt7ksx3 posted in this thread. I use the Python libraries for my project, but surprisingly my project can't even do a screen print. It gives segmentation fault as soon as the program starts. I tried to use the libraries from the old SDK version (2.3.1+31549) and keep the 33747 package installed. The program works fine, but when I plug in the leap motion device in USB port, I get this error:

AttributeError: type object 'object' has no attribute 'getattr' error

And when I quit the program, I get:

Failed to parse a message from a zero-copy input stream

I guess these errors are caused by mixing the old libraries with the new package. But, then why can not I launch my program if I am using the sdk 2.3.1 + 33747 package libraries?

[mnx]

leapd runs fine there, but I have to start it manually every time with sudo leapd. Also it throws an error for not being installed properly every time I run apt-get as if it just want to remind me how low priority linux is for the leap developers.

Ubuntu 16.04 LTS user here, freshly joined the community. I have both of the above mentioned problems, the one with the installer and the corrupted-double linked list. Downloaded file is Leap-2.3.1+31549-x64.deb. There has never been any previous version on my system, this is the very first time I install this stuff.

How come that this problem has been around for almost 4 years now? Is it that difficult to reproduce?
