[ncl-install] possible directory error in ncl-6.4.0 test script?

[Kevin Hallock]

Hi Sam,

Your configuration appears to be correct. Please note that setting NCARG_RANGS is only necessary if the lib/ncarg/database/rangs directory is in a non-standard location relative to NCARG_ROOT; in your case, it seems that setting NCARG_RANGS should not be necessary, although having it set should not cause any problems.

The ng4ex script is not essential to running NCL and is frequently used to test a variety of NCL scripts to determine if a new NCL binary built from source has all of its features enabled. Could you please run “ncl $NCARG_ROOT/lib/ncarg/nclex/xyplot/xy01n.ncl” to try running this example directly? That should tell us if the issue is in the ng4ex script or in NCL itself.

Thanks,
Kevin

If you have any old environment variables left over from a previous installation, then you may need to change them, or not set them at all.
