  in my  simple script i changed just one line to get it working with
new lazarus git sources:


   ' old svn code:

   #  svn co http://svn.freepascal.org/svn/lazarus/trunk lazarus

   new code ( git needs to be installed )

   git clone https://gitlab.com/freepascal.org/lazarus/lazarus.git lazarus


Alternative: look how its done by fpcupdeluxe:

good luck!
