build hdf5 with parallel I/O support

[fanfani]

Hello FreeBSD folks!

I'm trying to edit the aforementioned port Makefile in order to build the package with parallel I/O support (with no luck so far). I'm really a FreeBSD n00b so maybe I am missing something ;-)

According to the upstream docs this should be just a matter of

CC=/usr/local/bin/mpicc ./configure --enable-parallel

and, in fact, if I manually download the source code, explode the tarball and run the above command I get confirmation from ./configure output that parallel I/O is enabled, and then, hitting make the code builds just fine.

Now I'd really like to use the ports system to install the package, so I try to edit /usr/ports/science/hdf5/Makefile accordingly, which means changing the lines

CONFIGURE_ARGS= --enable-cxx \
                --enable-hl \
                --enable-instrument \
                --enable-strict-format-checks

to

CONFIGURE_ARGS= --enable-parallel \
                --enable-hl \
                --enable-instrument \
                --enable-strict-format-checks

( --enable-cxx and [I]--enable-parallel[/I] options are mutually exclusive) and run


# CC=/usr/local/bin/mpicc make install clean


but as the ./configure output scrolls I find out that parallel I/O support is not enabled. I also tried to add the CC variable definition also inside the Makefile but nothing changes.

...am I missing something?

Thank you,
Emiliano

Yes:

configure: error: --enable-cxx and --enable-parallel flags are incompatible. Use --enable-unsupported to override this error.

But
--enable-unsupported
seems not to work. You can try remove
--enable-cxx
.

(Btw, I am can't find the QUOTE tag).

Yes:
You can try remove --enable-cxx

I did. As I said, i replaced --enable-cxx with --enable-parallel inside the Makefile.

Sorry.
http://docs.h5py.org/en/latest/mpi.html

HDF5 must be built with at least the following options:

$./configure --enable-parallel --enable-shared

Note that --enable-shared is required.

Forgot: you have to create a new pkg-plist file. Either with make makeplist|tee -a pkg-plist or with ports-mgmt/genplist.

 

[fanfani]

did that.

Forgot: you have to create a new pkg-plist file. Either with make makeplist|tee -a pkg-plist [...]

and that too.

however, i get still:

Features:
---------
                  Parallel HDF5: no

btw,

it would be cool IMHO if the option to compile hdf5 with parallel I/O would be easily available in the "official" science/hdf5 port (ie. a checkbox in the usual dialog box), i think is a feature that most hdf5 users would find useful.

is there a place where i can file a feature requesto to the port mantainer?

is https://bugs.freebsd.org the right place for feature requests?

thank you

Yes, it is.
