Hi,
I just recently downloaded the gnu toolchain
when i invoke the openmp flag, it fails
$ aarch64-none-elf-gfortran -c -o mod_constants.fppized.o -fopenmp -O3 -march=native mod_constants.fppized.f90 aarch64-none-elf-gfortran: error: unrecognized command line option '-pthread' [yhuerta@cn4002 build_base_compsys.0000]$ aarch64-none-elf-gfortran --version GNU Fortran (GNU Toolchain for the A-profile Architecture 9.2-2019.12 (arm-9.10) ) 9.2.1 20191025 Copyright (C) 2019 Free Software Foundation, Inc.

that is not the case, when i used the gcc9 compiler i downloaded directly from gnu gcc website
$ gcc-gcc9 -c -o mod_constants.fppized.o -fopenmp -O3 -march=native mod_constants.fppized.f90 $ [yhuerta@cn4002 build_base_compsys.0000]$ gcc-gcc9 -v Using built-in specs.

do i need to compile aarch64-none-elf-gfortran and add openmp support to it?
thanks
