Hello ,
I'm a noob in fortran
I used to use an old fortran program on a unix machine (5 Years ago)
I'm tryig to reuse now on a windows machine. I'm trying to compile it in vain (usign ifort .in an intel compiler using : ifort mkmodel.f)
I know i should use fft libraries but i don't know how.
This is the program i'm trying to compile.
Thanks in advance (i cans send you the file i'm trying to compile)
I regularly compile SPICE2G.6 Fortran 77 source on various platforms and, until recently, it was quite straightforward. However, most 'modern' compilers merely preprocess the Fortran source into 'C', then run gcc on that. The preprocessors are badly broken, and the compilation fails - especially on Linux.
However, the Fortran compiler supplied with Cygwin in 2018 works fine, and produces a Win64 executable.
Try gfortran instead. Here's the guide should work perfectly.
1. You can install the fft library for windows from- http://www.fftw.org/install/windows.html
2. Create a module: http://www.fftw.org/doc/Defining-an-FFTW-module.html (guide)
3. And add it to the windows search path: https://docs.microsoft.com/en-us/previous-versions/7d83bc18(v=vs.140)?redirectedfrom=MSDN (follow this path guide)
4. First compile the program: gfortran -c -o test.o test.f90
6. Then, link it with fft library: test.o -LC:\fftw-3.3.4-dll64 -lfftw3-3 ( let's say you have installed it on C:\ directory)
Hope it helps.
We develop tools for migrating, modernising and debugging Fortran codes. (Have a look at http://simconglobal.com ). I would be happy to have a look at your code to see whether I can make it work. You can reach me at [email protected] .
Best wishes,
John
