undefined symbol: _ZNSt6atomicI8MAV_TYPEE5storeES0_St12memory_order

[TSC21]

Since last update, I get this after launching the node:

/home/vision/vision_ros_ws/devel/lib/mavros/mavros_node: symbol lookup error: /home/vision/vision_ros_ws/devel/lib//libmavros_plugins.so: undefined symbol: _ZNSt6atomicI8MAV_TYPEE5storeES0_St12memory_order

What could this be?

[tonybaltovski]

Try sudo apt-get distro-upgrade

[TSC21]

@tonybaltovski when I said "update", I meant mavros code update. Not related with Ubuntu distro.

[tonybaltovski]

Is your mavros installed from source or debs? distro-upgrade has nothing to do with the distro of Ubuntu.

[TSC21]

It was installed from source. It's not a missing depency, I just confirmed.

[tonybaltovski]

Delete the build, devel and install folders in your catkin workspace.

[TSC21]

Already did it and catkin_maked the ws but same error.

What version of gcc (gcc --version)? Strange that it not fail before (when i introduce std::atomic).

[TSC21]

gcc --version output:

gcc (Ubuntu/Linaro 4.6.4-1ubuntu1~12.04) 4.6.4`

@TSC21 Please check this workaround.

[TSC21]

Working! 👍 Can close now...

[TSC21]

@vooon I'm getting another similar problem now trying to launch:

/home/vision/vision_ros_ws/devel/lib/mavros/mavros_node: symbol lookup error: /home/vision/vision_ros_ws/devel/lib//libmavros_plugins.so: undefined symbol: _ZNKSt6atomicIdEcvdEv

Can you see how to fix this? Thanks!

Update: it's a std::atomic issue again.

Strange, gcc 4.6 at travis build correctly. I expect that at least build-in types should work.

Can't tell also. It compiles fine also in mine. But when roslaunching the mavros_node, it doesn't work.

It's working fine now! Thanks!
