Build fails due to addition of GroupFastBulkRead and GroupSyncBulkRead

[vishcomestrue]

I just pulled humble branch and when I tried building the package, colcon throws out an error and seems like it has something to do with the addition of GroupFastSyncRead and GroupFastBulkRead. I am adding the screenshot of the builderr for you reference! Hope to get this solved as soon as possible.

Also this seems like to have appeared after merging pull request #15 where the CHANGELOG.rst file also mentions the same.

Hi @vishcomestrue , thanks for leaving the issue.

Based on our tests, it seems that the issue is caused by the version of the Dynamixel SDK. The binary release version that can currently be installed with the following command:

sudo apt install ros-humble-dynamixel-sdk is an older version that does not yet support GroupFastSyncRead and GroupFastBulkRead.

We have released a new version, but it will take some time before it gets updated.
Until then, you can manually fetch the latest SDK by running:

git clone -b humble https://github.com/ROBOTIS-GIT/DynamixelSDK.git

and build it together with your project to resolve the issue.

We might have missed updating some manuals. Do you know if there is any manual that still instructs users to use:
sudo apt install ros-humble-dynamixel-sdk Let us know!

Hey @yun-goon , thanks a lot. Sorry for such a late reply, I tested it on the same day but yeah forgot to update you.

And yes, sudo apt install ros-humble-dynamixel-sdk is still recommended by OpenManipulator-X's official installation manual.

Hi @vishcomestrue ! Oh, I see. We missed that. Thanks for letting us know!
I'll keep this issue open for now, just in case, until the SDK's binary release is available.

I will close this issue after updating the manual
