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

compiler_version#

Name#

compiler_version(3) - [COMPILER:INQUIRY] Compiler version string

Synopsis#

    result = compiler_version()

     character(len=:) function compiler_version()

Characteristics#

  • The return value is a default-kind scalar character with system-dependent length.

Description#

compiler_version(3) returns a string containing the name and version of the compiler.

Options#

None.

Result#

The return value contains the name of the compiler and its version number used to compile the file containing the compiler_version(3) call.

Examples#

Sample program:

program demo_compiler_version
use, intrinsic :: iso_fortran_env, only : compiler_version
implicit none
