---- End of my messages on Rpi4/Buster with free pascal environment fp-ide ...
I have buyed a new Rpi4/4Go on Kubii.fr and set up a new buster raspbian system on the new card.
This morning I have rebuilt a new fp-ide on this card by :
sudo apt-get install fp-ide
All works find in the set up but when compiling my welcome "blaise.pas" the same system error occurs !
by mending the directories under the TP7-IDe-like the program is well executing like in the precedent card.
So I think that the Free Pascal Editor for Buster/Rpi4 is not operational.
( Also units Crt, PtcGraph, PtcCrt are to be implemented because they aren't found under EDI).
