Skeleton_app creation #5

Open kid-cmd opened 3 years ago

kid-cmd commented 3 years ago

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.

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

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!
