How to use autoware auto ros2 stack with matlab? ros2genmsg error

Hi,

Autoware is a common ros2 based framework for autonomous driving. https://gitlab.com/autowarefoundation/autoware.auto

when trying to open a ros2 bag file containing autoware messages in matlab, one needs to first run ros2genmsg on the Autoware message types.

However, when calling

ros2genmsg("/home/user/autoware_fork/src/external/autoware_auto_msgs")

matlab complains with

Identifying message files in folder '/home/user/autoware_fork/src/external/autoware_auto_msgs'..Done.
Validating message files in folder '/home/user/autoware_fork/src/external/autoware_auto_msgs'..Done.
Error using ros.internal.custommsgs.checkValidityOfMessages
No message files found in folder '/home/autoware_fork/src/external/autoware_auto_msgs/autoware_auto_control_msgs/msg'.

Error in ros2genmsg (line 89)
    [pkgMsgFiles, pkgSrvFiles] = ros.internal.custommsgs.checkValidityOfMessages(pkgDirs,folderPath,'ros2', pkgInfos);

Error in ground_non_ground (line 4)
ros2genmsg("/home/user/autoware_fork/src/external/autoware_auto_msgs")

Autoware is using some kind of precompiled .idl messages there, which matlab fails to understand.

user@rosgo:~/autoware_fork/src/external/autoware_auto_msgs/autoware_auto_control_msgs$ ls msg/
AckermannControlCommand.idl  AckermannLateralCommand.idl  HighLevelControlCommand.idl  LongitudinalCommand.idl

How can I import this message type into matlab?

Hi Max,

Thanks for your interest in this feature. This is something our development team is aware and we are considering it. Currently we are supporting only .msg files.

We will consider giving support to .idl files in future releases. Thanks for your feedback.

Thanks

Hari
