Re: Problem compiling HDF components in NCL 6.0.0 on AIX

Hi Peter,

We've had some internal discussions on this.

I first want to make sure that you compiled HDF correctly for use with
NCL. That is, did you compile it with NetCDF disabled, and the HDF
include files installed to their own "hdf" directory?

Your HDF "configure" line would have looked something like this:

  ./configure --prefix=/usr/local --with-zlib=/usr/local --with-jpeg=/
usr/local --includedir=/usr/local/include/hdf --disable-netcdf

For more information, please see:
