Trying to add a use iso_c_binding statement in an hello world example, I am quite confused:
$ flang hello.f90
./hello.f90:2:9: error: Cannot read module file for module 'iso_c_binding': Source file 'iso_c_binding.f18.mod' was not found
use iso_c_binding
^^^^^^^^^^^^^
error: Semantic errors in hello.f90
flang: in /home/osboxes, flang-new failed with exit status 1: /usr/bin/flang-new -fc1 -module-suffix .f18.mod -fdebug-unparse -fno-analyzed-objects-for-unparse hello.f90
I used flang but the error message says flang-new failed. And why the iso_c_binding module is not available?
