fftw3f does not have the fortran bindings. sfftw

I am running:

I did a port install of fftw-3-single. In this install there should be a fortran wrapper. The calls should be of the form sfftw….

Is this a difference in 3.3_0 and the current version of fftw 3.1.2? Can this be fixed?

Examine the output of "port variants fftw-3-single"; you should find that you can create the fortran wrappers by selecting the gcc variant of your choice.

All the update to 3.3 did was to update the version, nothing changed wrt the fortran bindings. Which gcc variant are you using? What do you mean about 3.1.2 being the current version of fftw?

[clirakis (Chris)]

I have not used any of the prior version of macports so I can't comment on change bringing the current version to 3.3.

Will variants give me any other choices other than fftw-3-single? I assume that this port just enables the --enable-single flag in the fftw configure script. If so, this should have the fortran bindings in it.

I am using the xcode mac version of gcc. I don't happen to be next to my mac right now. I believe it is gcc 4.1.2 but I'm not sure, BTW gfortran is also the apple xcode variant.

Yes the version of fftw that I downloaded off the website was 3.1.2 and when I compile it, the bindings do exist so I'm pretty sure it doesn't have anything to do with the compiler.

Is there a way I can substitute my compiled version and make ports think it installed a copy of fftw?

The fortran bindings are only enabled if you specify one of the gcc variants otherwise there is no fortran compiler available as Xcode doesn't incude a fortran compiler. If you look at the port the --disable-fortran flag is passed unless one of the gcc variants is used.

Xcode doesn't contain a fortran compiler, so if you are not using one of the gcc variants that will explain why the fortran bindings aren't being built. What do you mean by gfortran being an Xcode variant?

Yes the version of fftw that I downloaded off the website was 3.1.2 and when I compile it, the bindings do exist so I'm pretty sure it doesn't have anything to do with the compiler.

In that case it seems that you have a fortran compiler, where did you get it from? Where is it installed?

No

[clirakis (Chris)]

It is gfortran and when I do a gfortran -V it comes up as a apple osx supplied version. I'll dig further when I get home from travel and post here.

So are you saying that I can change the flags on the port during compile if I want? Chris

That is not coming from Xcode, it would be useful to know where it came from?

By using the variants you can.

I promised that I'd publish the results from the fortran dump.

gfortran -v

Does that help?

[skymoo (Adam Mercer)]

Not really, where is the compiler installed, i.e. whats the output of which gfortran?

[skymoo (Adam Mercer)]

ping, where is the gfortran installed. I can't go about trying to address this ticket without that information.

No response, reopen if this is still a problem.
