Am trying to compile a free-format fortran file with some subroutines in it, with gfortran complaining

gfortran -O3 -ffree-form -o kamkrai-sort.f

compilation terminated.

The -o option names the output file, but you have told the compiler to use your input file as the output file.

What is the appropriate command that generates the object file only ?
