[gradsusr] Will grads be in spack?

Tue Jan 8 08:45:17 EST 2019

Jennifer, et al,

I just did a quick scan of this page:

  http://cola.gmu.edu/grads/gadoc/supplibs2.html

and tried to match with spack packages. Most had pretty good matches 
(though they might be called "libX" instead of "X"), and the only 
libraries I couldn't find are:

  dap
  gadap
  shapelib

and there are two that I don't think are quite right:

  udunits ==> spack has udunits2
  g2clib  ==> spack has grib-api, eccodes

You said to ignore dap/gadap, so I'm happy with that. Note that in my 
testing I'm always building netcdf with the dap variant and it works for 
that at least:

[(513) 08:43 AM] $ ncdump -hsc 
https://opendap.nccs.nasa.gov/dods/GEOS-5/fp/0.25_deg/fcast/inst1_2d_hwl_Nx/inst1_2d_hwl_Nx.20181222_12 
| head -20
netcdf inst1_2d_hwl_Nx {
dimensions:
	lat = 721 ;
	lon = 1152 ;
	time = 123 ;
variables:
	double time(time) ;
		time:grads_dim = "t" ;
		time:grads_mapping = "linear" ;
		time:grads_size = "123" ;

shapelib seems pretty standard in its build, so a package for it seems 
possible.

udunits was the precursor to udunits2, so a package for it probably 
isn't impossible either though we might need to talk with spack about 
naming it as "udunits" nowadays usually refers to the udunits2 package 
(udunits1?).

You have instructions for g2clib as well so it's probably doable as 
well, but ECMWF's (deprecated) grib-api and eccodes are in spack. I'm 
guessing, though, that the APIs are not the same?

I was rushing to get them into some kind of working state when releasing version 2.2.1 right before my position at COLA ended. Please use the source code at https://github.com/j-m-adams/GrADS, and not the tarball from COLA, which is missing a few scripts. I will try to incorporate the patches from Steve Woodbridge as quickly as I can. Not all libraries use the PKG_CONFIG model, so it is a mix of strategies for finding what is needed. I definitely rely on $LDFLAGS, $CFLAGS, $CPPFLAGS, and $LD_LIBRARY_PATH to find everything. The grib2 library is a good example of one with non-standard features -- that lib is barely supported within NCEP and has zero bells and whistles for simplifying your life; you have to edit the makefile to tweak the build and then copy files manually to install them outside of the local directory. Don't bother with dap/gadap. What else is not available in Spack?

This has involved learning how to make new spack packages, which has been interesting (and not quite fully successful yet, to be honest, but I'm learning!). Now, Baselibs started as an offshoot of Supplibs, so I am learning some useful and perhaps relevant lessons.

GEOS inherited this as it expects Baselibs to all be under one place as well. With GEOS I have the "luxury" of knowing its very odd non-standard GNU Make build system and could probably hack it to find spack's libraries without too much trouble, but GEOS relies on fewer libraries than GrADS.

Does anyone out there have experience building GrADS with --enable-dyn-supplibs? If you've documented how to get GrADS to find and use system libraries, spack might be okay with that (with, say, loooong LDFLAGS, LIBS, CPPFLAGS lines). The only other thought would be finding an autotools hacker who could expose all the supplibs with --with-PKG options.
