I have this happen all the time, basically everytime I update my console app, or web app that runs on a Pi.... The app will start, then quit by itself. The error logs show nothing, the Linux Sys log(s) show only the startup and the log entries I have coded into the app - but nothing with regard to why the app would spontaneously quit!
Tonite, I updated the SQLite database, and added Xojoversionstring to the app so it would write it to the database on start, and then could be read by a web app page.
Can anyone tell me some clues to solve why this is happening and what to do about it?
In some cases, it has been Xojo version - I have better luck with 2017R3 than any of the 2018 versions. But again, it is different from app to app. ie some apps compiled in 2018Rx are fine, some are not. Some must be done in 2017R3. Sometimes it is helpful to shut down the Pi, sometimes it does not matter (just stop the app, upload new and restart the app). Very very strange!
Anyway, this is an enormous problem since it take hours to get it figured out, and there is never a ryhm or reason as to why it finally works! Not good for something that should be production ready!
