Hi ZoriaRPG.
The Allegro units should be in the "units" directory. On my Windows system it is at "c:/lazarus/fpc/3.0.4/units/i386-win32/". I've created a directory named "allegro" and put files inside.
I didn't used Allegro 4.4 a long time ago. I know they did an update a few time ago. Let me know if it works.
I would also like to see some sample Pascal programmes using the lib, so that I can see how to access its headers and contents. e.g., the Allegro 'fix' type stuff, the BITMAP datatype, and so forth.
AFAIK nobody actually used Allegro.pas 4, except myself. You may find a list of my uses in
this FPC thread. Note that some use version 5.
