Compiler switches for directory in GNAT project files

Compiler switches for directory in GNAT project files

[Björn]

I have a number of source files in a GNAT project which have been
automatically generated. I want to compile these source files with
different compiler switches from the rest of the project (e.g. less
warnings).

All of the automatically generated files are located in one single
folder. Up until now I've specified them one by one in the project
file: for Switches ("foo.adb") use ... However, the list of specified
files have now grown well over a hundred.

Is there a way to specify specific compiler switches for all files
contained in a specific directory in GNAT project files?

You could create a separate project file for that directory.

Yes, I guess this is what I'll do.
I was hoping for some syntax: for Switches ("/*"), but I didn't find
anything when I scanned the user guide.

There asre two ways:

You can use the "Case" statement if you use an external/internal 
variable

  type SRC_Type is ( "default", "easy", "advance" ) ;
  --
  SRC : SRC_Type := external ( "SRC", "default" ) ;

  case SRC is
    when "default" =>
        for Source_Files  use ( "libraries_1.adb", 
                                "print_1.adb",
                                "environment_1.ads" ) ;
    when "easy" =>
        for Source_Files  use ( "libraries_2.adb", 
                                "print_1.adb",
                                "environment_2.ads" ) ;
    when "advance" =>
        for Source_Files  use ( "libraries_3.adb", 
                                "print_2.adb",
                                "environment_1.ads" ) ;
  end case;
  --
  -- or you can use the "for Swiches" statement
  --
  package Compiler is
    for Default_Switches ( "Ada" ) use ( "-gnat95" ) ;  -- default 95 specs
    --
    for Switches ( "Program_1.adb" ) use ( "-gnat05" ) ;  -- Ada 2005 specs
    for Switches ( "Program_2.adb" ) use ( "-gnat12" ) ;  -- using Ada 2012
  end Compiler ;
