--- Comment #9 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Tobias Burnus <bur...@gcc.gnu.org>: https://gcc.gnu.org/g:2ba0376ac40447ce7ee09fcef00511c18db25dfa commit r12-2839-g2ba0376ac40447ce7ee09fcef00511c18db25dfa Author: Tobias Burnus <tob...@codesourcery.com> Date: Tue Aug 10 17:26:32 2021 +0200 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.
