2016-11-02 00:40:48 -0500 | commented question | How to fill a sensor_msgs/image without a memcpy ? Ideally they would have a nodelet receiving the sensor_msgs::Image in a callback so the serialization would be skipped. However the initial copy from the driver is still wasted cycles. They aught to be able to create a custom allocator. |
2016-03-11 16:31:24 -0500 | answered a question | ctrl-c shutdown of nodelet manager versus calling shutdown inside of nodelet manager I did find something that works! You have to configure your node launch XML to indicate that the nodelet which will call exit(x) is required. Then when it detects a failure, it will kill the entire launch file. then inside nodelet you can call "exit(err);" with some error in err. Well I did the following incase there's some other path: I really want it to exit. |

2015-09-08 02:08:37 -0500 | commented question | library not found for -lpcl_io I have the same problem. When I add "-L/usr/local/lib" in the link.txt it fixes it but this is not permanent as the changes are blown away next time I build apparently. |
