Am I understanding you correctly that you don'tget any compiler errors > when you are compiling these files with pragma Ravenscar ???! 'Fraid so! (other than the aforementioned error on 'pragma Attach_Handler') 4 warnings about not using anything in the units 'with'-ed but other than that a clean compile (after commenting out the 'pragma Attach...'). I'm using Win32 GNAT 3.13p (20000509) with options "-gnatybefhik -gnato -gnatv" I also tried the other options "-gnaty -gnato -gnatv -gnatwe -gnatwl -gnatwu". There is a fair bit of 'tidying' to do to keep GNAT happy about formating but again a clean compilation/link occurs. I don't understand why you are trying to use these packages directly - aren't they just there for the benefit of the compiler? (Though I'm guessing that it isn't the use of them directly that is causing the problem - dodgy installation of GNAT maybe?)
