Trouble decoding lcm message

[camkisailus]

Hi!

I followed the README using my custom message type mbot_encoder_t

package mbot_lcm_msgs;

struct mbot_encoder_t
{
    int64_t utime;
    int64_t leftticks;
    int64_t rightticks;
    int16_t left_delta;
    int16_t right_delta;
}

rosmsg-gen.sh, rosrepub-gen.sh and catkin build complete without error, but when I run roslaunch lcm_to_ros mbot_republishers.launch this error message is printing error -1 decoding mbot_encoder_t!!! Before any messages are even published to LCM? What is it attempting to decode?

FWIW my config looks like so:

# LCM to ROS republisher with normal hash
MBOT_ENCODERS, mbot_lcm_msgs, mbot_encoder_t, lcm2ros

Any help is much appreciated!

Hello, I'm not 100% sure, but maybe could you also look at the generated messages after rosmsg-gen, do they look OK? And/or you could post them here to check. Then, I will try building yours locally and see if I get an issue.

OK, I may have an answer. There is a mistake (which I will fix) where the message header doesn't get created if the directory for the message package name doesn't already exist. So in your case, could you try creating an mbot_lcm_msgs directory in the lcm_to_ros directory, then running rosmsg-gen again, check that a mbot_lcm_msgs\mbot_encoder_t.hpp file appears in and see if that helps? Then I will fix the error properly
