Connection to node=/davis_ros_driver failed: param client failed

[bochenxie]

Dear Developers,

Following the steps in the webpage, I install this driver. The system version is Ubuntu 18.04 LTS.

However, I find that there are some errors when I use "roslaunch dvs_renderer davis_mono.launch" with a DAVIS 240C camera. The driver cannot connect the DAVIS 240C, as shown in the following log.

Could you give me some advice for this case? Thanks a lot for your help.

Have a similar situation. Below is the gdb information I got.

I also have the some issue. I am getting a segmentation fault when I try to run davis_ros_driver by it self.

Segmentation fault (core dumped)

By disconnect an connecting the camera am I guessing the crash happens when the driver connects to the camera.

Also I successfully installed it and run it in June on a different pc and re-installation on that one works fine.

A wild guess is that it is a dependency that has updated and it causes the crash but I have no idea what dependency and it could be some thing else.

All this are done on ubuntu 18.04.

Hello, the issue is most probably the new version of Boost we have in our iniVation PPA repository, a package called 'boost-inivation'. The ROS build system seems to get confused about which Boost to use at compile and runtime, which leads to this crash. A quick fix is to uninstall the 'boost-inivation' package, then clean and rebuild the ROS packages, then they should work again.

@grammers Thanks for your good advice!

By running apt purge boost-inivation I got it to work! Thanks for the help!

[llongi]

Just for your info, we're also fixing this on boost-inivation package side to prevent conflicts in the future. A future release of boost-inivation will move the custom install to /opt/inivation/boost/ instead of /opt/boost-inivation/, which stops it from being auto-discovered and interfering with libcaer/ROS. I'll update this issue again when we release that update.

[Schweizliu]

仅供您参考，我们还在提升升级包方面修复了此问题，以防止将来发生冲突。 boost-inivation 的未来版本会将自定义安装移动到 /opt/inivation/boost/ 而不是 /opt/boost-inivation/，这会阻止它被自动发现并干扰 libcaer/ROS。当我们发布该更新时，我将再次更新此问题。

When I run sudo apt-get remove boost-inivation or sudo apt purge boost-inivation, I get this problem: Unable to locate package boost-inivation. I have updated the software source through the command "sudo apt-get update", but it has no effect. When I check whether the software has been installed through the command "sudo dpkg -l | grep*", there is no display, indicating that my system does not have this software package. So how to solve this problem "[WARN] [1680231915.210308595]: Camera calibration file /home/syou/.ros/camera_info/DAVIS-00000567.yaml not found."
