[Trilinos-Users] [EXTERNAL] Re: decomp tool Error

[Sjaardema, Gregory D]

What size mesh are you decomposing (#elem, #block, #node) and how many processors are you decompsing it for?

Did you also install hdf5 and reference it in the netcdf build for netcdf-4 support, or is it a netcdf build only?

The current getopt that you have will work, but will give reduced functionality in regards to long options which you can see by entering -H and -h and seeing the difference.  I'm not sure if installing the gnu-getopt in parallel with the system getopt would cause issues or not, but on my and many other macs we have both installed and have not noticed any issues (However, I use port instead of brew).

Sai,

I believe your using homebrew as a package manager so use:

brew install getopt

To install the getopt command line utility.

Hi,

I installed Trilinos and Peridigm (official versions hosted on GitHub) on my Mac OS X 10.11.3, including the dependencies boost, hdf5 and netcdf. I followed the instructions on Sandia's Peridigm installation guide to the dot.

The Peridigm unit tests all passed, which is good. However, when I try to use the decomp tool from Trilinos, I get the following errors:


########################################################################
The "getopt" executable that is available on this system is an older
version that is not compatible with the needs of the "decomp" tool.
If possible, you should update your getopt to a newer version and make
sure that the new getopt is in your path.

Below are some options for getting the current getopt version:
* If on a Mac: "sudo port install getopt"
* Search the internet for "getopt-1.1.5" or "getopt-1.1.4"; download and build

Enter "-h" for the modified options that this version supports.
Enter "-H" for the options that the standard version supports.

There are multiple errors here.

1) I don't know how to update the getopt executable. It seems Mac OS X already comes with a built in version (which I checked and found to be in /usr/bin), but this version in not compatible with decomp. I checked Homebrew, and there is a key only option to install gnu-getopt, but they have a warning that installing different versions in parallel can cause trouble. I'm not able to find any other working way to install get opt with out causing errors.

2) NetCDF error about exceeding dimensions. I installed the latest version of netcdf-c, 4.4.0. I changed the numbers in netcdf.h as instructed in the Peridigm installation guide. I have a feeling that this may have something to do with the error, but I'm not quite sure. All tests passed, however, when I installed netcdf from source.

There may be other errors I'm not seeing. Please, I would appreciate if I can get some guidance on how to address these errors.

Sai
