I am not sure if there is a simple answer. From a google search it looks like there are available bindings for gfortran that one can download, and there are ways (<a href="http://stackoverflow.com/questions/11955378/check-that-iso-c-binding-is-available-at-compile-time">http://stackoverflow.com/questions/11955378/check-that-iso-c-binding-is-available-at-compile-time</a>) to check if your compiler has it.<div>
<br></div><div>If it is not available you could try changing "use, intrinsic "" ISO_C_BINDING" to "use :: MYISO_C_BINDING" in fftw_modules.F and try one of the versions that can be downloaded and renaming it appropriately.</div>

I found that version 12.1 requires ISO_C_BINDING module.<br>
this is a Fortran 2003 extension and some f90/f95 compilers don't support it.<br>
For the users who use that compilers, should they choose version 11.1?<br>
if anyone know the workaround, please advise.<br>
<br>
