GNAT - filename/unitname question

GNAT - filename/unitname question

[Manuel Collado]

Consider the following source file:

filename.adb
------------
   procedure unitname is
   begin
      ...
   end unitname;

Compiling it gives a warning:

   filename.adb:1:11: warning: file name does not match unit name, should
   be "unitname.adb"

And generates the files:

   filename.ali
   filename.o


The question is: is there a gcc switch or GNAT pragma to force the 
compiler to use the unitname for the object files? To have:

   unitname.ali
   unitname.o

instead of filename.* object files.

I've read the GNAT documentation for gcc switches and pragmas, but found 
nothing useful.

Thanks,

IIRC, pragma Source_File_Name provides some scheme.

You could compile with -gnatwe to treat warnings as errors. This may
be beyond what you are looking for :-)

On the whole,most people find it easier to go with what the compiler
wants (you could try gnatchop; it takes the units in an arbitrary
source file and outputs each unit in the "expected" file).
