Re: ESMF_RegridWeightGen not found

Hi Mary & Sean,

on the Mac systems, we use Macports to install ncl. �Doing so requires that I download and place the ncarg-xxx.tgz file in the proper place in the Macports tree. �I�ll have to check whether this method uses the Linux or the Mac tgz file for its source. �It may be that it uses the Linux tgz file, which may/may not have the build for the binary you are discussing.

Macports has been moving to binary installations, however I suspect that ncl_ncarg is one that is built from source. �This may be the �source� of the issue.

We are compiling on the Macports compiled code with gcc-4.5, on our 10.6.8 Macs. �gfortran is not installed, and certainly no libraries compiled by gfortran should exist on any of our systems.

Which computer are you looking at concerning this issue, Sean, Sif or Tintagel?

Hi Mary,

I attempted to join the ncl-talk list after getting my post pinged because I hadn't joined. But I guess I'm awaiting approval now?

Hi Sean,

Yes, it was awaiting approval and I just approved it. Thanks for doing this.

I'm CC'ing the person who installed NCL on my machine. I'm not sure how he installed it, but I doubt he built it from source. Roy, how did you install NCL on our macs?

More information: The "ESMF_RegridWeightGen" binary should be in the same directory as the "ncl" binary. You can verify this with :

ls $NCARG_ROOT/bin/ncl
ls $NCARG_ROOT/bin/ESMF_RegridWeightGen

Of course, this means that NCARG_ROOT must be set correctly. It looks to me like it is, otherwise you would be seeing different error messages.

I just verified that the "ESMF_RegridWeightGen" binary is indeed included in the MacOS 10.6.8 / NCL V6.1.2 tar file that we provide on the ESG:

ncl_ncarg-6.1.2.MacOS_10.6_64bit_gcc460.tar.gz

If this is the file you used for the installation, then it should be there.

Thanks,
Sean

The ESMF_RegridWeightGen command should have been installed with NCL, unless NCL was built from source code.

How did you install NCL on your system?

Hi,

I'm having a problem with ESMF_regrid which seems to be that the unix command ESMF_RegridWeightGen is not found. �To make the problem easy to illustrate, I adapted Example 1 from the ESMF_regrid() documentation, and used the file air.mon.ltm.nc from the NCEP/NCAR reanalysis. I uploaded the .nc file to the CGD ftp site given on the webpage.

Here is the example script....

Fri Dec 27 12:33:25 sif scripts> more ex1.ncl
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/esmf/ESMF_regridding.ncl"

begin
������infile = "/Users/sdavis/sd-data/ncep/ncep.reanalysis.derived/pressure/air.mon.ltm.nc"

��sfile = addfile(infile,"r")
��temp �= sfile->air(0,0,:,:)

��Opt ���������������= True

��Opt@SrcFileName ���= "src_SCRIP.nc"
��Opt@DstFileName ���= "dst_SCRIP.nc"
��Opt@WgtFileName ���= "NCEP_2_Rect.nc"
��Opt@ForceOverwrite = True

��Opt@SrcMask2D �����= where(.not.ismissing(temp),1,0)

��Opt@DstGridType ���= "5x5"
��Opt@DstLLCorner ���= (/ -60.d, ��0.d/)
��Opt@DstURCorner ���= (/ �60.d, 355.d/)

��temp_regrid = ESMF_regrid(temp,Opt)
��printVarSummary(temp_regrid)
end

And here's what happens when I try to run it...

I'm running NCL on Mac OSX 10.6.8.

Any ideas on what could be causing this problem?

Thanks!!
