[Bug fortran/20811] New: gfortran include problem (regression from g77)

[afranck at gmx dot de]

Hello,

doing some experiments with gfortran, I stumbled across the following
bug/regression with respect to g77:

consider these two files in a directory "test":

$ cat test/foo.f:
      subroutine foo
      include   'test.h'
      end

$ cat test/test.h
c  just a comment

Now, compiling with g77:

~ $ g77 -c test/foo.f
[works ok]

and with gfortran:

~ $ gfortran -c test/foo.f
Error: Can't open included file 'test.h'

If I compile within "test":

~/test $ gfortran -c foo.f
[works ok]

everything is fine.

But "include" is IMHO supposed to include from where the source file is located,
not only in the current directory?

Greetings,
Andreas

FYI, ifort_8.0.046, Absoft Fortran 95 9.0 EP, pgf95 6.0-2, SGI f90 7.4, and g95
will all find and use the included file in the same directory as the source
without requiring extra '-I' command line options.

Adding -I. to FC in the Makefile of libgfortran makes my compile happy again.

After this patch libgfortran fails to build on darwin-ppc.

it does not find the selected_int_kind.inc in the libgfortran objdir when
building libgfortran. (selected_int_kind.f90 compilation)

Reverting the patch brings me to a successful libgfortran build.

You should really attach patches and not the files themselves. Now, I don't
know exactly what you changed in those files. And I'm really wondering what you
could possible change in Makefile.in :)

I'm assigning this bug to myself, as I intend to look into it in the next few
days.

The two attached files will change the behavior so that included files are
processed as described in comment #2. I have not checked the results
extensively.
