compiler_options

Name

compiler_options(3) - [COMPILER:INQUIRY] Options passed to the compiler

Synopsis

    result = compiler_options()

     character(len=:) function compiler_options()

Characteristics

• the return value is a default-kind character variable with system-dependent length.

Description

compiler_options(3) returns a string with the options used for compiling.

Options

None.

Result

The result contains the compiler flags used to compile the file containing the compiler_options(3) call.

Examples

Sample program:

program demo_compiler_version
use, intrinsic :: iso_fortran_env, only : compiler_version
use, intrinsic :: iso_fortran_env, only : compiler_options
implicit none
   print '(4a)', &
      'This file was compiled by ', &
      compiler_version(),           &
      ' using the options ',        &
      compiler_options()
end program demo_compiler_version
