fftw-3: Not building universal variant

[andre.david@…]

Hi,

I am using a data analysis package (root.cern.ch) that build x86_64 and I like that. This package has an interface to fftw-3, but when compiling it, I get:

g++ -O2 -m64 -dynamiclib -single_module -undefined dynamic_lookup -install_name /Users/adavid/root/lib/libFFTW.dylib -m64 -o lib/libFFTW.dylib fftw/src/TFFTComplex.o fftw/src/TFFTComplexReal.o fftw/src/TFFTReal.o fftw/src/TFFTRealComplex.o fftw/src/G__FFTW.o -ldl -L/opt/local/lib -lfftw3
ld: warning in /opt/local/lib/libfftw3.a, file is not of required architecture
ln -fs libFFTW.dylib lib/libFFTW.so
==> lib/libFFTW.dylib done

So I thought I just needed to uninstall fftw-3 and ask for it with +universal. The problem is that:

$ sudo port -d -v install fftw-3 +universal

Warning: the following items did not execute (for fftw-3): org.macports.activate org.macports.configure org.macports.build org.macports.destroot org.macports.install

It seems like something's broken. If it is my compiler, please help me figuring it out.

Thanks,

Andre

Attached the fftw-3 config.log

Ok, I am actually debugging as I post. (Sorry for that.) I have used Monolingual to get rid of all ppc stuff on my macbook pro, hence no ppc arches in /Developer.

Therefore the question becomes: is there a way to define universal as i386+x86_64 (no ppc)? Or even better: create a variant for building both 32 and 64 bit version of the arch of the given arch--allbits, perhaps?

Thanks for your reading,

Andre

PS - I will be looking where the universal variants are defined...

[andre.david@…]

Though I am not Tcl literate I nailed the location to /opt/local/share/macports/Tcl/port1.0/portconfigure.tcl, where

# internal functions to determine the "-arch xy" flags for the compiler
# -> these should preferably get a more global scope, perhaps be user-configurable?
set universal_archs {ppc ppc64 i386 x86_64}

I would second this. Or an alternative like "allbits" (tongue in cheek,) which gets set i386+x86_64 on intel and ppc+ppc64 on ppc.

Sounds plausible?

Unfortunately, the problem isn't over. Replacing the above line with

set universal_archs {i386 x86_64}

compiles what seems like all the code, but then brutally stops:

I guess this provides grounds for an actual request that universal is broken in fftw-3.

I confirmed that fftw-3 is not universal. It seems difficult for me to make it so since fftw-3 tries to optimize for an architecture. I set universal_variant no at this time. Let me know if I am in the wrong and there is a way.

[Veence (Vincent)]

fftw-3 cannot be made universal an easy way. When I try to add a universal variant and blindly compile it with -arch i386 -arch x86_64, gcc don't even go further the first compilation phase because the command line uses -M options which are forbidden with multiple archs (the preprocessor output differs according to the arch being compiled for). There is no other way to build a fftw-3 universal but to create a per arch temp directory, compiling each version for one arch, and then use lipo to gather the multiple .dylib files into a universal one. I wonder if this can be done with a script under MacPorts 1.7.

[Veence (Vincent)]

I have a fix. I put the modified Portfile, which based on the graphics/cairo solution, here:

​ftp://ftp.cimaxonline.fr/Portfile_fftw3_universal

Please try it out and let me know.

universal Portfile, from 10.50@…, attached

I'll test this but it will probably be next week before I get a chance, I imagine the same will work for fftw-3-single?

[skymoo (Adam Mercer)]

I'll check this

Normally, yes. This is a fairly general universal build framework solution: the code is duplicated in subdirectories corresponding to each arch, then separately configured with the right arch flag and compiled therein, then the results are joined through lipo into a universal file. It should be satisfactory for build processes that use -M or -E or any other option not compatible with multiple arch switches in gcc.

I will test your Portfile. Could take a while since I am busy. Could you diff -u and upload the patch? The added part is straightforward but not short. I wonder if your approach is incorporated in port command since it may be applicable to other similar ports.

patch for universal variant of fftw-3

[Veence (Vincent)]

I have attached the patch in universal diff Sorry for being late, I was away these days. Thanks for testing it

[tenomoto (Takeshi Enomoto)]

I confirmed that it works. I have just committed. Thanks a lot.
