Bug ID: 96661 Summary: configure:16984: error: unsupported system, cannot find Fortran int kind=16 Product: gcc Version: 11.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libgomp Assignee: unassigned at gcc dot gnu.org Reporter: danglin at gcc dot gnu.org CC: burnus at gcc dot gnu.org, jakub at gcc dot gnu.org Target Milestone: --- Host: hppa64-hp-hpux11.11 Target: hppa64-hp-hpux11.11 Build: hppa64-hp-hpux11.11 Whiling configuring libgomp, the following error occurs: configure:16984: error: unsupported system, cannot find Fortran int kind=16, nee ded for omp_depend_kind ## ---------------- ## ## Cache variables. ## ## ---------------- ## ac_cv_build=hppa64-hp-hpux11.11 ac_cv_c_compiler_gnu=yes Looks like this was introduced by: 2020-07-23 Tobias Burnus <tob...@codesourcery.com> * configure.ac: Add OMP_DEPEND_KIND and OMP_INT128_SIZE. * libgomp_f.h.in (omp_check_defines): Check whether sizeof of determined Fortran kind and C typedef match. * omp_lib.f90.in: Add omp_depened_kind. * omp_lib.h.in: Likewise; fix omp_alloctrait_key_kind. * configure: Regenerate. * Makefile.in: Regenerate. * testsuite/Makefile.in: Regenerate. Guess this is because target doesn't support int128. For the most part, libgomp used to work on this target.
