Re: [Ifeffit] Demeter 0.9.19

Hi Matt, I agree with everything you say. Thanks for taking the time to explain. As someone who uses fortran all the time, it makes sense for me to own Ifort, but since it's only free for academics on Linux, that's not true for most people. Actually, for FEFF our philosophy is also that it should compile with any compiler on any platform. We respond to EVERY compilation issue and never tell people to use another compiler. However -- most of our users don't want to compile code at all: they like a nice binary that I've compiled for them. (I doubt that the ifeffit/demeter users would object to this option ;).) For that, I like to use Ifort - for my purpose it's the better compiler. But we make sure that FEFF compiles well using gfortran etc. also. If I were to successfully built the codes on this mailing list, I'll definitely share the recipe, as well as any kind of binary other people can use without having to build/compile/... . It won't be for today, unfortunately :). Cheers, Kevin On Fri, Jan 10, 2014 at 7:28 AM, Matt Newville wrote:

I can concur with others here that making something work on Mac can be a miserable experience. Sometimes you have to admit defeat and change the approach.

Anyway, I tried "sudo port install p5.16-ifeffit" and failed:

dependencies -- does anyone else suspect "port" of being designed to fill hard disks as fast as possible?) System is 10.9 generally up-to-date with most things. pgplot seems to fail during extraction.

I doubt that I'd be able to contribute a lot to this project, but I can test things.

Also I'm surprised to read so much about gfortran about this thread, but maybe I'm missing some common knowledge on the project ... I am generally much happier with Ifort.

If you or anyone else wants to use ifort or any other compiler, that would be fine. For many years, I did keep a license for Digital/Compaq/Intel Fortran on Windows in order to make the Windows dlls for distribution of the Ifeffit package. Even on Windows, this stopped being necessary, as the MinGW suite began including gfortran.

Unlike Feff, these are open source projects, and we absolutely insist that anyone interested can use, (try to) build, and distribute these programs -- both Bruce and I are begging for such help, actually. Requiring non-free tools simply to build these programs would definitely put a burden on potential developers. I don't see any reason for why that would be necessary, especially on Linux and Mac, for which the system compilers are gcc (or gcc/llvm) which includes a working fortran compiler.

Many free software projects (notably for me, scipy, but also the macports that Frank mentioned) use gfortran on Macs. And gfortran works fine for me for many things on 10.6 and 10.8. I can compile the basic ifeffit library and other fortran libraries used in Larch (though I did recently notice some dependency issues between 10.6 and 10.8, as the compiler version changed, and haven't tried 10.9 yet). I have not been able to build PGPLOT (perhaps not crucial for Demeter) or the Ifeffit-Perl bridge successfully on 10.8. I believe this is probably a matter of getting the compiler / linker arguments correct....

If you or anyone else can get these codes to build using ifort, more power to you. If so, can you post your solution?
