            Bug ID: 98754
           Summary: gnatmake no longer recognizes -P option
           Product: gcc
           Version: 10.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ada
          Assignee: unassigned at gcc dot gnu.org
          Reporter: emr-gnu at hev dot psu.edu
  Target Milestone: ---

Using 10.2.0, "gnatmake -Pfoo" does not appear to be a valid command line
anymore.  Contents of foo.gpr:

project foo is
   for Source_Dirs use (".");
   for Object_Dir use "./build";
   for Exec_Dir use ".";
   for Main use ("hello");

   package Compiler is
      for Default_Switches ("Ada")
          use ("-fstack-check",
               "-ffloat-store",
               "-msse2",
               "-mfpmath=sse",
               "-O0",
               "-gnatws",
               "-gnatE",
               "-gnato");
   end Compiler;
end foo

I would expect gnat to start building the program defined by "hello", but
instead I receive:

try "gnatmake-10.2 --help" for more information.

--- Comment #1 from Arnaud Charlet <charlet at gcc dot gnu.org> ---
Yes, that's as expected: support for project files has been moved entirely to
gprbuild. If you have gprbuild in your path, gnatmake -Pproject will call
gprbuild -Pproject.

--- Comment #2 from Eric Reischer <emr-gnu at hev dot psu.edu> ---
In that case, this is not a RESOLVED WONTFIX -- this is still open.  The
documentation and output of "gnatmake --help" need to be updated to reflect the
fact this is no longer a valid command line option.

--- Comment #3 from Eric Reischer <emr-gnu at hev dot psu.edu> ---
(Or some other more descriptive error indicating "gprbuild" was not found on
the path, rather than acting as though you have borked the command-line
options.)
