Its posible to port cedserver for ARM? Im thinking about replacing my more than 10 years old, pentium 4 computer with Raspberry-Pi.
Probably yes, as far as I can tell even without much trouble. FreePascal support ARM in different flavours. Since you probably also use Linux, lNet (the networking library cedserver uses) should also compile and run fine.
Just give it a shot, it should compile without any changes :) I don't have any ARM device around so I can't really test it.
