merge fftw3 3.3.2-1 (main) from Debian sid (main)

[Aditya V]

See comment 7

original report
Please sync fftw3 3.3.2-1 (main) from Debian sid (main)

Explanation of the Ubuntu delta and why it can be dropped:
  * Merge with Debian; remaining changes:
    - Revert the ARM workaround.

As far as I can tell, there is no Ubuntu delta (checked by using 'bzr diff -r tag:3.3-1 -r tag:3.3-1ubuntu1', and there was no output), so there is no Ubuntu delta to be dropped. Also, this package now has support for multiarch (fixes bug 781726).

Changelog entries since current quantal version 3.3-1ubuntu1:

fftw3 (3.3.2-1) unstable; urgency=low

  * Team upload to unstable
  * New upstream release
  * enable avx on i386 too, detected at runtime
  * move wisdom tools to libfftw3-bin, make libfftw3-dev multiarch same
  * revert split into -mt package
    package size gain is negiglible compared to main library
  * drop debian/patches/fix-links.patch applied upstream
  * remove empty directories from libfftw3-dev
  * respect DEB_BUILD_OPTIONS parallel
  * add myself to Uploaders

  * debian/rules:
    - pass MPILIBS=mpicc --showme:link to configure to ensure correct
      mpi linkage
    - remove rpath from mpi libs with chrpath, add build-depend on it
    - remove unneeded quilt.make and the build-depend
  * wrap-and-sort debian directory
  * minor package description cleanup

[Julian Taylor (jtaylor)]

unfortunately its a bit more complicated than a sync due the library being in main.
fftw3 in debian now depends on mpi which is not in main. I guess it would need to be patched out as adding mpi to main is unlikely.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Mattias Johnsson (m-t-johnsson)]

I'd also like to add a request for pulling the most recent Debian version of fftw 3.3 (more specifically fftw-dev), precisely *because* it includes MPI support as well as AVX support, which the Ubuntu version doesn't.

I'm one of the authors of the XMDS2 numerical differential equation solver (www.xmds.org), and our XMDS2 installer for Ubuntu currently has to download the source for FFTW 3.3 and compile it on the local machine with MPI and AVX configuration options. This slow and fragile. Pulling FFTW in from the Ubuntu repos like all the other dependencies would be really nice.

I'm not completely sure how the Ubuntu repositories are organised, but if the openmpi package isn't going to move to main, could an MPI / AVX enabled-version of FFTW 3.3 sit in Universe? Or would different builds of the same package in different repositories be a non-starter?

[Alessio Treglia (quadrispro)]

As Julian said above, openmpi is in universe, so this needs a merge.

[Alessio Treglia (quadrispro)]

Unsubscribing sponsors for now.

[Julian Taylor (jtaylor)]

merging should still be delayed a bit
debian might get an mpich2 version too.

[Julian Taylor (jtaylor)]

well that died away
attached a debdiff merging it without mpi

I'll add and extra source package in universe for mpi later

[Clint Byrum (clint-fewbar)]

Hi Julian, thanks for submitting this. I took a look at it for sponsorship, but I have one reservation.

Could you document in the changelog why you changed the cflags?

If that is indeed the old Ubuntu delta, then please merge in the full changelog.

Thanks! Please re-subscribe sponsors upon addressing this.

[Julian Taylor (jtaylor)]

you mean for the long long test?
thats just to shut up debians build log checks

the debdiff is branched of debians git, not the current package, those changes just aren't worth an upload in debian but we might as well add them to ubuntu.

[Mattias Johnsson (m-t-johnsson)]

Great! Good to see Universe at least will get the MPI version.

[Rohit R (rr0hit)]

Once this is done can it be backported to precise? The MPI enabled version would benefit people like me who run 12.04 on clusters for scientific computation purposes.

[Stéphane Graber (stgraber)]

Uploaded.
