Re: Hint to Ada newbies

[Per Sandberg <per.s.sandberg@bahnhof.se>]

Som more hints on switches:

This is a snippet of my usual project file during development. It will 
force me to keep a consistent layout and catch a lot of errors during 
compile and tests.

my.gpr:
------------------------------------
project My is

    for Source_Dirs use ("src");
    for Object_Dir use ".obj";
    for Main use ("main.adb");

   package Builder is
     for Default_Switches("Ada") use ("-k", "-j0");
     for Global_Configuration_Pragmas use project'Project_Dir & "my.gpp";
     --  Initialize data to bad values.
   end Builder;

   package Compiler is
       for Switches ("ada") use
         ("-gnatyybcfhiklnprtu", "-gnatyN256", "-gnaty3", -- Check 
layout.
          "-gnatVa", --  Turn on all validity checking options
          "-gnatwa", --  Turn most info/Warning
          "-gnatwe", --  Treat all warnings as errors
          "-gnata",  --  Enable Assertions.
          "-gnateE", --  Generate extra information in exception 
messages
          "-gnatQ"); --  Don't quit, write ali/tree file even if compile 
errors
    end Compiler;

    package Binder is
       for Switches ("ada") use
         ("-E");  -- Store callstack in exceptions.
    end Binder;
end Test_My;
------------------------------------
my.gpp
----------------------------------
pragma Initialize_Scalars;
--------------------------------
