I am using centos and elgis repo and for me it is working..
so there must be a problem with the hdf linking or compile of the library.
Note hdf4 is responsible to do the job not hdf5 for the particular case.
gdal_translate 'HDF4_EOS:EOS_GRID:"MCD15A2.
A2002185.h12v05.005.2007172035551.hdf":MOD_Grid_MOD15A2:LaiStdDev_1km'
test2.tif
Input file size is 1200, 1200
0...10...20...30...40...50...60...70...80...90...100 - done.
