unable to run youbot_simulation on ros noetic

[RozFa]

Hello,
I have read the previous issues and authors seem to have solved their problems. I got youbot_simulation and youbot_description. I had the following errors using catkin build :

error: ‘CONSTRUCTED’ was not declared in this scope 836 | state_ = CONSTRUCTED;
error: ‘CONSTRUCTED’ was not declared in this scope 844 | if (state_ != CONSTRUCTED)
error: ‘INITIALIZED’ was not declared in this scope 879 | state_ = INITIALIZED;

also when I use roslaunch youbot_gazebo_robot youbot.launch gazebo doesn't start.

I am new to Ros and I can not figure out how to fix these.

Hi @RozFa , you might be using the default kinetic-devel branch. Try compiling the noetic-devel branch, and it should at least fix the errors during catkin build.

I had the same idea. but I double checked and got the noetic-devel.
I'm afraid these happened with noetic branch

that's odd, because these errors were specifically addressed in c4fb88f.

Also, if you look at the line numbers mentioned in your error message, the noetic-devel branch shows updated code (see line 836 for example)

maybe I made a mistake writing noetic=devel at it just got the default version.
I changed those part manually and no more errors in catkin build. thank you
