Skeleton_app creation

[kid-cmd]

Hello I am a student who wants to add the skeleton app to my cFS.

I git clone skeleton app to the apps file path and populated the other necessary file paths needed for sample apps creation and there were still issues.

I implemented the changes noted in the issue logs such as the CCSDS_CommandPacket_t #4 changes and followed #2 "Add integration instructions" 's changes for how they got it working however I tend to run into errors. Some examples include what is shown in the reply below.

Is there a guide for a noob like me to integrate the app onto cfs. NASA has such robust and great documentation but i still havent managed. Am i not placing the app name in the correct locations? Am i missing commands i should be running? full breakdown for a beginner plz.

(Shows this below despite me changing it to CFE_SB_CmdHdr_t)
‘CCSDS_CommandPacket_t’ undeclared (first use in this function); did you mean ‘CCSDS_SpacePacket_t’?
SKELETON_ReportHousekeeping((CCSDS_CommandPacket_t *)Msg);

upon compiling. When making changes the cFS runs without showing skeleton app, aborts, or shows what is below.

and the similar #2

Hi! Thanks for the question! Check out our cFS training package. Specifically the steps in Exercise 7 (page 188) should get you most of the way there. https://ntrs.nasa.gov/citations/20205011588. Swap out SCH for skeleton and you should be good to go!
