<font size="2" face="DejaVu Sans Mono">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:</font><br>
<br>
<font size="2" face="DejaVu Sans Mono">[ 38%] Built target gdal_HDF4</font><br>
<br>
<font size="2" face="DejaVu Sans Mono">but the command you gave
gives not HDF4</font><br>
<br>
<font face="DejaVu Sans Mono"><span lang="EN-US"
style="mso-fareast-language:EN-US">gdalinfo --format hdf4</span></font><br>
<font face="DejaVu Sans Mono"><span lang="EN-US"
style="mso-fareast-language:EN-US"></span></font><br>
<font face="DejaVu Sans Mono"><span lang="EN-US"
style="mso-fareast-language:EN-US">(should be "formats"
instead?)</span></font><br>
<font face="DejaVu Sans Mono"><span lang="EN-US"

face="DejaVu Sans Mono"><span lang="EN-US"
style="mso-fareast-language:EN-US">gdalinfo --formats hdf4<br>
<br>
this retrieves a long list, but no HDF5:<br>
<br>
gdalinfo --formats | grep hdf<br>
HDF5 -raster,multidimensional raster- (rovs): Hierarchical
Data Format Release 5 (*.h5, *.hdf5)<br>
<br>
on the other hand </span></font><br>
<font face="DejaVu Sans Mono"><font size="2">gdal-config --formats<br>
<br>
gives:<br>
<br>
gdal-config --formats<br>
MEM vrt HDF4 MEM<br>
<br>
So it should be there?<br>
<br>
This is confusing. Will keep looking.<br>
<br>
Thank you for your time, Jukka!<br>

<p class="MsoNormal"><span
style="font-size:10.0pt;font-family:"DejaVu Sans Mono",serif">I
recently compiled a minimal GDAL (3.10) with HDF4 support
(using HDF 4.3.0) for processing MODIS L1B data. However,
the resulting command line tools cannot understand the
format. Perhaps I am doing something wrong, or missing
something important, or both.<br>
<br>
Do I understand correctly that MODIS L1B in HDF-EOS format
should be readable by GDAL compiled with HDF4 support
without additional libraries?<br>
<br>
Thanks for any hint.<br>
