[ncl-install] 5.2.0 install, error with mpex15

[Mary Haley]

Hi Mark,

I think you did the right thing. The "ncargex" script needed to be updated to force "-lpng" on the compile line for this example. This will be in the next release of NCL.

Thanks for letting us know about this.

If you want to make the change yourself, edit the file $NCARG_ROOT/bin/ncargex and change:

    case mpex15:
        set other_data_files = (Europe.png Europe.pngi)
    breaksw


to:

    case mpex15:
        set other_data_files = (Europe.png Europe.pngi)
        set comp_flags = ($comp_flags "-lpng -lz")
    breaksw


--Mary
