Hi Carol, re: > Ok, thanks for helping with my curiosity!

I was expecting to see an undefined reference to a shared library, but I don't see anything unusual about this listing other than it being rather long. As a comparison, here is 'ldd' output for the 'ncdump' that gets built and installed as part of McIDAS: % which ncdump /home/mcidas/bin/ncdump % ldd `which ncdump` linux-vdso.so.1 => (0x00007fff79548000) libnetcdf.so.7 => /home/mcidas/mcidas2018/netcdf/liblib/.libs/libnetcdf.so.7 (0x00007f76a7fc9000) libhdf5.so.8 => /home/mcidas/mcidas2018/hdf5/src/.libs/libhdf5.so.8 (0x00007f76a7aff000) libdl.so.2 => /lib64/libdl.so.2 (0x0000003cf1e00000) libm.so.6 => /lib64/libm.so.6 (0x0000003cf2600000) libz.so.1 => /lib64/libz.so.1 (0x0000003cf2a00000) libc.so.6 => /lib64/libc.so.6 (0x0000003cf1600000) librt.so.1 => /lib64/librt.so.1 (0x0000003cf2200000) /lib64/ld-linux-x86-64.so.2 (0x000055941dbe9000) Have you tried running the version of 'ncdump' that gets built as part of a McIDAS installation? If yes, what are/were the results? re: large and consistently sized netCDF output files; wrong? > Yes, I think this is incorrect. When I create area files for meteosat, the > file sizes are all different for all the bands. We'll know more when you can do an 'ncdump' on the files you are creating.
