Barbara, Thank you very much for your clear answer. I am not seeing an issue. The reason for my query is that I am trying to figure out how best to install NetCDF-4.3.0 and HDF4 such that there are no conflict with libraries or with the ncdump and ncgen utilities.
What I plan to do is install HDF-4.2.9 using --disable-netcdf and then rename HDF4's ncdump and ncgen to h4dump and h4gen. Then, I will install NetCDF-4.3.0 using --enable-hdf4 so that it can read HDF4 files and there won't be name clashes since HDF4 was built with --disable-netcdf. And, since I renamed the HDF4 utilities there won't be confusion about which ncdump and ncgen is found in a user's path and causing problems. Now that I know --disable-netcdf doesn't affect the ncdump and ncgen utilities, I think my plan should work. Thanks for your help, Chris ----------------------------------------------------------------------------------------------------------- Christopher W.
