Hello,

as openmpi currently does not build on hydra, a lengthy list of failed
dependent packages appears:
   http://hydra.gnu.org/eval/75135#tabs-now-fail
This contains packages such as a2ps, alsa-utils, automoc4, gnunet, imagemagick,
qt etc., which a priori have no relationship with mpi.

I did not follow all dependency chains, but one of the culprits is fftw, as a
dependency of pulseaudio.

Would it not make sense to create a separate package that has openmpi as an
additional input?

Then I think it would be good to analyse the complete dependency chains
starting with openmpi.

Andreas

Ah yes, we must definitely keep an MPI-less version of fftw.

Eric, could you do that?

TIA,

Apparently the build failure has to do with the hwloc copy bundled in
the Open MPI tarball, which may be old.

I’ve added hwloc, so we can eventually use it instead.

Now there is an old hydra problem popping up at
   http://hydra.gnu.org/build/55792/nixlog/1/tail-reload :

guix build: error: open-file: No such file or directory: "/gnu/store/q5l0ph9yr025qz97xni0fqwfc45x7lhg-fftwf-3.3.4.drv"

It was supposed to be fixed, but apparently is not.

Yes, I noticed.  :-/

I’ll see what I can do.

Thanks Eric for addressing the issue.

Commit e5c66f8 does:

+(define-public fftw-openmpi
+  (package (inherit fftw)
+    (name "fftw-openmpi")
+    (inputs
+     `(("openmpi" ,openmpi)
+       ,@(package-inputs fftw)))
+    (arguments
+     (substitute-keyword-arguments (package-arguments fftw)
+       ((#:configure-flags cf)
+        `(cons "--enable-mpi" ,cf))))
+    (description
+     (string-append (package-description fftw)
+                    "  With OpenMPI parallelism support."))))

I don’t think I’ve mentioned it before, but we should refrain from using
‘string-append’ in descriptions, because that prevents i18n (xgettext
won’t catch it.)

Instead, I’d suggest leaving ‘description’ unchanged, and writing
‘synposis’ in full, with “(with MPI support)” added at the end.
See ‘unionfs-fuse/static’ for an example.
