So now I am trying to configure the --RTS option in GPS. First I tried to include the two Windows Scenario variables ADAINCLUDE and ADALIB with the correct RTS path, but still the builder returns me the same error message ("avr-gnatmake: RTS path not valid: missing adainclude and adalib directories").

Secondly I tried to include the following lines inside .gpr file, but the result was the same.

   type Ada_Include_Type is ("""c:\GNAT\2011\lib\gcc\avr\4.5.3\rts-zfp\adainclude""");
   Ada_Include : Ada_Include_Type := external ("ADAINCLUDE", """c:\GNAT\2011\lib\gcc\avr\4.5.3\rts-zfp\adainclude""");
   
   type Ada_Lib_Type is ("""c:\GNAT\2011\lib\gcc\avr\4.5.3\rts-zfp\adalib""");
   Ada_Lib : Ada_Lib_Type := external ("ADALIB", """c:\GNAT\2011\lib\gcc\avr\4.5.3\rts-zfp\adalib""");

And finally I tried to set the path directly on package Builder, so I used 

   package Builder is
      for Executable_Suffix use ".elf";
      for Default_Switches ("Ada") use ("--RTS=c:\GNAT\2011\lib\gcc\avr\4.5.3\rts-zfp --mmcu=avr5");
   end Builder;

and also the error message did not change.

Would someone have an idea on how to fix this?
