            Bug ID: 101660
           Summary: FAIL: gfortran.dg/bind_c_array_params_3.f90
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: msebor at gcc dot gnu.org
  Target Milestone: ---

In a recent x86_64 build I see a number of failures in the gfortran test suite:

   FAIL: gfortran.dg/bind_c_array_params_3.f90 (6: -12)
   FAIL: gfortran.dg/ISO_Fortran_binding_10.f90 (6: -12)

   FAIL: gfortran.dg/PR94327.f90 (6: -12)

The failures have also been reported here:
https://gcc.gnu.org/pipermail/gcc-testresults/2021-July/709815.html

Most (all?) of the failures are due to:

gcc/testsuite/gfortran.dg/bind_c_array_params_3_aux.c:8:10: fatal error:
ISO_Fortran_binding.h: No such file or directory
compilation terminated.
compiler exited with status 1
FAIL: gfortran.dg/bind_c_array_params_3.f90   -O0  (test for excess errors)
Excess errors:
gcc/testsuite/gfortran.dg/bind_c_array_params_3_aux.c:8:10: fatal error:
ISO_Fortran_binding.h: No such file or directory
compilation terminated.

UNRESOLVED: gfortran.dg/bind_c_array_params_3.f90   -O0  compilation failed to
produce executable

--- Comment #2 from Tobias Burnus <burnus at gcc dot gnu.org> ---
The problem is the patch set for PR 101305, which moved from a static
  libgfortran/ISO_Fortran_binding.h
to a generated
  $build/$arch/libgfortran/ISO_Fortran_binding.h

And in the include file:
  -#include "../../../libgfortran/ISO_Fortran_binding.h"
  +#include "ISO_Fortran_binding.h"

I am not quite sure whether that should be "..." or now "<...>".

Notes:
* When doing incremental builds, ISO_Fortran_binding.h was not build; I had to
  delete $build/{*,*/*}/libgfortran/  (or $build to do a proper bootstrap)
  to get it generated.

* Here, it does work in that case with in-build-tree testing, except that with
  testing -m64 and -m32 at the same time, the wrong header is used,
  cf. https://gcc.gnu.org/pipermail/gcc-patches/2021-July/576194.html

It would be useful to know:
* whether you did an incremental build or not (cf. above)

* whether your are testing in build tree or with the installed compiler.
→ If the latter, does changing "ISO_Fortran_binding.h" to
<ISO_Fortran_binding.h> help?

* Do you use RUNTESTFLAGS - in particular  --target_board=  to run multiple
archs at the
  the same time (→ email above)

--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I think it should be <ISO_Fortran_binding.h> .
Anyway, at least on Fedora it fails because we install the
ISO_Fortran_binding.h
header not to /usr/include but to
/usr/lib/gcc/<target>/<version>/include/ISO_Fortran_binding.h
and so when using xgcc -B ... the just built compiler can't use the system
compiler's version, which IMHO is the only reason why it could succeed for
Sandra or anyone else.
We need an -I ... option that will point the compiler to the libgfortran build
directory (and do so correctly for the current multilib).

    testsuite/lib/gfortran.exp: Add -I for ISO*.h [PR101305, PR101660]

    This patch adds -I$specdir/libgfortran to GFORTRAN_UNDER_TEST, when
    set by proc gfortran_init. As the $specdir depends on the multilib
    setting, it has to be re-set for a different multilib; hence, we track
    whether a previous call to gfortran_init set that var or whether it
    was set differently.

    gfortran: Fix in-build-tree testing [PR101305, PR101660]

    ISO_Fortran_binding.h is written in the build dir - hence, a previous
commit
    added it as include directory for in-build-tree testing.  However,
    it turned out that -I$specdir/libgfortran interferes with reading .mod
files
    as they are then no longer regareded as intrinsic modules.  Solution:
Create
    an extra include/ directory in the libgfortran build dir and copy
    ISO_Fortran_binding.h to that directory.  As -B$specdir/libgfortran already
    causes gfortran to read that include subdirectory, the -I flag is no longer
    needed.

            PR libfortran/101305
            PR fortran/101660
            PR testsuite/101847

    libgfortran/ChangeLog:

            * Makefile.am (ISO_Fortran_binding.h): Create include/ in the build
dir
            and copy the include file to it.
            (clean-local): Add for removing the 'include' directory.
            * Makefile.in: Regenerate.

    gcc/testsuite/ChangeLog:

            * lib/gfortran.exp (gfortran_init): Remove -I$specpath/libgfortran
            from the string used to set GFORTRAN_UNDER_TEST.
