Chapter 2 Developing with LF Fortran
-[N]DAL
Deallocate Allocatables
Compile only. Default: -dal
Specify -dal to deallocate allocated arrays that do not appear in DEALLOCATE or SAVE
statements when a RETURN, STOP, or END statement is encountered in the program unit
containing the allocatable array. Note that -ndal will suppress automatic deallocation for
Fortran 95 files (automatic deallocation is standard behavior in Fortran 95).
-[N]DBL
Double
Compile only. Default: -ndbl
Specify -dbl to extend all single-precision REAL and single-precision COMPLEX variables,
arrays, constants, and functions to 64 bit double-precision. If you use -dbl, all source
files (including modules) in a program should be compiled with -dbl. Specifying -dbl may
or may not result in a somewhat slower executable.
-[N]DLL
Dynamic Link Library
Link only. Default: -ndll
Specify -dll to create a 32-bit Windows dynamic link library (for more information, see
”Dynamically linked applications” on page 54).
-[N]F95
Fortran 95 Conformance
Compile only. Default: -nf95
Specify -f95 to generate warnings when the compiler encounters non standard Fortran 95
code.
Note that -nf95 allows any intrinsic data type to be equivalenced to any other intrinsic type.
-FILE filename
Filename
Compile and link. Default: not present
Precede the name of a file with -file to ensure the driver will interpret filename as the name
of a file and not an argument to an option.
Example
On the following command line, bill.f90 is correctly interpreted as a source file:
