Hi, I can't help you with building GDAL but I can show where to learn the difference between --formats and --format: https://gdal.org/en/latest/programs/raster_common_options.html#raster-common-options

That is interesting. I set cmake to build hdf4, cmake sees it and it does not throw errors during the build. In fact, I see: [ 38%] Built target gdal_HDF4 but the command you gave gives not HDF4 gdalinfo --format hdf4 (should be "formats" instead?) gdalinfo --formats hdf4 this retrieves a long list, but no HDF5: gdalinfo --formats | grep hdf HDF5 -raster,multidimensional raster- (rovs): Hierarchical Data Format Release 5 (*.h5, *.hdf5) on the other hand gdal-config --formats gives: gdal-config --formats MEM vrt HDF4 MEM So it should be there? This is confusing. Will keep looking. Thank you for your time, Jukka!

However, the resulting command line tools cannot understand the format. Perhaps I am doing something wrong, or missing something important, or both. Do I understand correctly that MODIS L1B in HDF-EOS format should be readable by GDAL compiled with HDF4 support without additional libraries? Thanks for any hint.
