Submission: etsf_io

[dstrubbe (David Strubbe)]

Portfile for ETSF_IO, an input/output library for electronic structure codes, intended for the science category.

[cooljeanius (Eric Gallager)]

I tried building it, and it ran into this error when configuring:

checking for /opt/local/include/netcdf.mod... no
checking for /opt/local/include/NETCDF.mod... no
checking for /opt/local/include/NETCDF.MOD... no
Action: install NetCDF and set its path with --with-netcdf-module-path.
configure: error: "No 'NetCDF' module found."
Command failed:  cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_LocalPorts_science_etsf_io/etsf_io/work/etsf_io-1.0.3" && ./configure --prefix=/opt/local --disable-dependency-tracking --with-netcdf-module-path=/opt/local/include --with-netcdf-ldflags=-L/opt/local/lib FCFLAGS=-O3 CFLAGS=-O3 
Exit code: 1

This is where netcdf-fortran puts its mods:

gl00b05046:~ egall$ port contents netcdf-fortran | grep mod
  /opt/local/include/TYPESIZES.mod
  /opt/local/include/mods32/NETCDF.mod
  /opt/local/include/mods64/NETCDF.mod

Not sure how you'd do this when building universal... maybe by using the muniversal portgroup?

[dstrubbe (David Strubbe)]

Hm, thanks for trying it out. Were you building etsf_io, netcd-fortran, or both as universal? netcdf-fortran puts its mods here for me, when building +gcc46 and not universal:

  /opt/local/include/NETCDF.mod
  /opt/local/include/TYPESIZES.mod

Not sure why this would be different. I don't see anything about mods explicitly in the netcdf-fortran Portfile. Also, there are no other ports depending on netcdf-fortran to use as a model, it seems from "port list depends:netcdf-fortran".

Both. I have +universal in my variants.conf file.

[dstrubbe (David Strubbe)]

I tried to build netcdf-fortran +universal, but it set off a cascade of rebuilds of dependencies, ending in an error (#39016), so I cannot reproduce.

Maybe something like this is needed?

variant universal {
    configure.args.delete   --with-netcdf-module-path=${prefix}/include
    configure.args.append   --with-netcdf-module-path=${prefix}/mod32/include
}

But, should it use mod32 or mod64?

If you use the `muniversal` portgroup​, I'm pretty sure you could use both... although I'm not sure how exactly though...

[cooljeanius (Eric Gallager)]

Cc Me!

[dstrubbe (David Strubbe)]

Well, maybe the simplest is just to add "universal_variant no". I am not sure how to use the portgroup.

[cooljeanius (Eric Gallager)]

Yeah, it could really use some more usage notes in its comments...

Edit: That's #32428

[dstrubbe (David Strubbe)]

Ok let's just have no universal, pending figuring out how to do that properly. Please review my revised Portfile submission.

Fetch fails because the host is offline. I found a copy of the distfile on ​Launchpad.

Configure fails:

checking for /opt/local/include/netcdf.mod... no
checking for /opt/local/include/NETCDF.mod... no
checking for /opt/local/include/NETCDF.MOD... no
Action: install NetCDF and set its path with --with-netcdf-module-path.
configure: error: "No 'NetCDF' module found."

Note that I do have netcdf-fortran installed with the universal variant. It appears that netcdf-fortran installs NETCDF.mod into a different place depending on whether it is installed with the universal variant or not. That makes it difficult for ports like etsf_io that want to use NETCDF.mod to know where it is. This might be a bug in netcdf-fortran; I've filed #39319 for that.

[ryandesign (Ryan Carsten Schmidt)]

Committed the port in r106631 with these changes:

• added launchpad download location (the main host is back up in the mean time)
• changed "mod32" and "mod64" to "mods32" and "mods64" in comment about netcdf-fortran universal
• added "require_active_variants netcdf-fortran {} universal" to ensure netcdf-fortran is not installed universal, until we figure out what to do about that
• instead of setting "FCFLAGS=-O3 CFLAGS=-O3" in configure.args, I set configure.optflags to "-O3"
