I have some confusion on the creation of these various packages from the link below. The instructions say I should catkin build. but catkin build doesn't make a devel folder. If I can catkin_make in the same works space then it just breaks stuff (to my understanding). I'm not sure what to do, because I need to source ../devel/setup.bash but can't do so with no devel directory.Link to github and instructions

This doesn't have enough information to be answerable, though you are right that catkin buildshould create the devel directory.

It might help us if you show us 1) Any error messages from catkin build: cd ~/catkin_ws; source /opt/ros/melodic/setup.bash; catkin build 2) the contents of your catkin workspace: cd ~/catkin_ws; tree -L 2

Please do explain what caused the problem you encountered and then accept your own answer.

@gvdhoorn For some reason i had created a bunch of build and devel files in my computer root(/home), I deleted them then the catkin build from my workspace root worked, I on't know how it happened but it's one of those I'll look for when catkin build doesn't work.
