COMPILER_OPTIONS

Module Intrinsic Inquiry Function: Returns a string containing the compiler options that were used for compilation.

Module

USE ISO_FORTRAN_ENV

Syntax

result = COMPILER_OPTIONS( )

Results

The result is a scalar of type default character of processor-defined length.

The return value is a list of the compiler options that were used for compilation.

Example

Consider the following file named t.f90:

use ISO_FORTRAN_ENV

character (len = :), allocatable :: res

res = compiler_options ()
print *, "len of res is: ", len (res)
print *, "('<<', A, '>>')") res

deallocate (res)
end

The following is the output:

Linux

 Lin$ ifx -o t.out -warn alignments -assume writeable-strings t.f90
Lin$ ./t.out
len of res is:           51
<<-o t.out -warn alignments -assume writeable-strings>>
