Bug ID: 101820 Summary: fatal error: ISO_Fortran_binding.h: No such file or directory Product: gcc Version: 12.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libfortran Assignee: unassigned at gcc dot gnu.org Reporter: ubizjak at gmail dot com Target Milestone: --- There are quite some FAILs in the gfortran testsuite, e.g.: FAIL: gfortran.dg/ISO_Fortran_binding_1.f90 -O0 (test for excess errors) FAIL: gfortran.dg/ISO_Fortran_binding_1.f90 -O1 (test for excess errors) FAIL: gfortran.dg/ISO_Fortran_binding_1.f90 -O2 (test for excess errors) FAIL: gfortran.dg/ISO_Fortran_binding_1.f90 -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions (test for excess errors) FAIL: gfortran.dg/ISO_Fortran_binding_1.f90 -O3 -g (test for excess errors) FAIL: gfortran.dg/ISO_Fortran_binding_1.f90 -Os (test for excess errors) ... where: /home/uros/git/gcc/gcc/testsuite/gfortran.dg/ISO_Fortran_binding_1.c:3:10: fatal error: ISO_Fortran_binding.h: No such file or directory compilation terminated. compiler exited with status 1 FAIL: gfortran.dg/ISO_Fortran_binding_1.f90 -O3 -g (test for excess errors) Excess errors: /home/uros/git/gcc/gcc/testsuite/gfortran.dg/ISO_Fortran_binding_1.c:3:10: fatal error: ISO_Fortran_binding.h: No such file or directory compilation terminated. UNRESOLVED: gfortran.dg/ISO_Fortran_binding_1.f90 -O3 -g compilation failed to produce executable The file ISO_Fortran_binding.h is present in the libgfortran build directory, but it looks to me that -I is missing when building the testcase: /home/uros/gcc-build/gcc/testsuite/gfortran/../../gfortran -B/home/uros/gcc-build/gcc/testsuite/gfortran/../../ -B/home/uros/gcc-build/x86_64-pc-linux-gnu/./libgfortran/ /home/uros/git/gcc/gcc/testsuite/gfortran.dg/ISO_Fortran_binding_1.f90 -fdiagnostics-plain-output -fdiagnostics-plain-output -O3 -g -pedantic-errors /home/uros/git/gcc/gcc/testsuite/gfortran.dg/ISO_Fortran_binding_1.c -dumpbase -B/home/uros/gcc-build/x86_64-pc-linux-gnu/./libgfortran/.libs -L/home/uros/gcc-build/x86_64-pc-linux-gnu/./libgfortran/.libs -L/home/uros/gcc-build/x86_64-pc-linux-gnu/./libgfortran/.libs -L/home/uros/gcc-build/x86_64-pc-linux-gnu/./libatomic/.libs -B/home/uros/gcc-build/x86_64-pc-linux-gnu/./libquadmath/.libs -L/home/uros/gcc-build/x86_64-pc-linux-gnu/./libquadmath/.libs -L/home/uros/gcc-build/x86_64-pc-linux-gnu/./libquadmath/.libs -lm -o ./ISO_Fortran_binding_1.exe /home/uros/git/gcc/gcc/testsuite/gfortran.dg/ISO_Fortran_binding_1.c:3:10: fatal error: ISO_Fortran_binding.h: No such file or directory compilation terminated. Adding "-I/home/uros/gcc-build/x86_64-pc-linux-gnu/libgfortran" to the above command fixes the compilation.
