libgcc_s.so.1 must be installed for pthread_cancel to work #306

Closed bergera closed 5 years ago

bergera commented 5 years ago

Hello there, long time user trying to update to the latest version.

Expected Behavior

Actual Behavior

I am using a Phidget 1048_0 4-input. When the ON button is clicked, Artisan crashes with the following console error:

libgcc_s.so.1 must be installed for pthread_cancel to work
Aborted (core dumped)

I can provide a core dump or Apport crash file if that you'd find it helpful.

I built libphidget22-1.0.0.20190116 from source and verified that it correctly reads from my connected 1048_0. The Phidgets TemperatureSensor Python example code works and produces correct readings.

libgcc_s.so.1 is installed:

$ locate libgcc_s.so.1
/lib/i386-linux-gnu/libgcc_s.so.1
/lib/x86_64-linux-gnu/libgcc_s.so.1
/snap/core/5897/lib/i386-linux-gnu/libgcc_s.so.1
/snap/core/5897/lib/x86_64-linux-gnu/libgcc_s.so.1
/snap/core/6034/lib/i386-linux-gnu/libgcc_s.so.1
/snap/core/6034/lib/x86_64-linux-gnu/libgcc_s.so.1
/snap/core/6130/lib/i386-linux-gnu/libgcc_s.so.1
/snap/core/6130/lib/x86_64-linux-gnu/libgcc_s.so.1
/snap/vlc/555/lib/x86_64-linux-gnu/libgcc_s.so.1
/snap/vlc/768/lib/x86_64-linux-gnu/libgcc_s.so.1
/snap/vlc/770/lib/x86_64-linux-gnu/libgcc_s.so.1
/usr/lib/gcc/x86_64-linux-gnu/6/libgcc_s.so.1
/usr/lib/gcc/x86_64-linux-gnu/7/libgcc_s.so.1
/usr/share/artisan/libgcc_s.so.1

Using LD_PRELOAD=libgcc_s.so.1 has no effect. I also tried rebuilding libphidget22 using LIBS="-lgcc_s" and that had no effect.

I have also tried versions of libphidget22 as old as libphidget22-1.0.0.20170711 and still encountered the same problem.

Steps to Reproduce the Problem

  1. Select any Phidget from Device menu.
  2. Click ON

I don't know why it didn't occur to me before, but running Artisan as root does not cause a crash. Still, it's not ideal, so I hope this issue is still helpful. A user would need to understand X to get this running, and either launch Artisan from the command line or edit the .desktop file to change the Exec entry.

$ xhost +local:
$ sudo artisan

I am not a linux expert, but did you setup the udev rules for the Phidgets as noted in the installation documentation https://www.phidgets.com/docs/OS_-_Linux ?
