how to support HDF-EOS format

[wxfei19@…]

I have a problem ! I can get the subdatasets in a hdf file,but when I use GDALOpen to open one of the subdatasets, It tell me that
"ERROR 4: `HDF4_EOS:EOS_SWATH:"d:\Swathc_Test.hdf":OnedGeo:CalB' does not exist i
n the file system,
and is not recognised as a supported dataset name."

why this happened?
what should I do if I want to support the hdf-eos format

Subdatasets:
  SUBDATASET_1_NAME=HDF4_EOS:EOS_SWATH:"d:\Swathc_Test.hdf":Simple:Temperature
  SUBDATASET_1_DESC=[100x40] Temperature (32-bit floating-point)
  SUBDATASET_2_NAME=HDF4_EOS:EOS_SWATH:"d:\Swathc_Test.hdf":Simple:Conduction
  SUBDATASET_2_DESC=[100x40] Conduction (32-bit floating-point)
  SUBDATASET_3_NAME=HDF4_EOS:EOS_SWATH:"d:\Swathc_Test.hdf":Simple:DataOne
  SUBDATASET_3_DESC=[100x40] DataOne (32-bit floating-point)
  SUBDATASET_4_NAME=HDF4_EOS:EOS_SWATH:"d:\Swathc_Test.hdf":Swath64:SensorA
  SUBDATASET_4_DESC=[100x40] SensorA (32-bit floating-point)
  SUBDATASET_5_NAME=HDF4_EOS:EOS_SWATH:"d:\Swathc_Test.hdf":SwathLatonly:Gain
  SUBDATASET_5_DESC=[100x40] Gain (32-bit floating-point)
  SUBDATASET_6_NAME=HDF4_EOS:EOS_SWATH:"d:\Swathc_Test.hdf":Swathco:BandC
  SUBDATASET_6_DESC=[100x40] BandC (32-bit floating-point)
  SUBDATASET_7_NAME=HDF4_EOS:EOS_SWATH:"d:\Swathc_Test.hdf":OnedGeo:CalA
  SUBDATASET_7_DESC=[100x40] CalA (32-bit floating-point)
  SUBDATASET_8_NAME=HDF4_EOS:EOS_SWATH:"d:\Swathc_Test.hdf":OnedGeo:CalB
  SUBDATASET_8_DESC=[100x40] CalB (32-bit floating-point)
  SUBDATASET_9_NAME=HDF4_EOS:EOS_SWATH:"d:\Swathc_Test.hdf":Index:Fakedata
  SUBDATASET_9_DESC=[40x40] Fakedata (32-bit floating-point)
ERROR 4: `HDF4_EOS:EOS_SWATH:"d:\Swathc_Test.hdf":OnedGeo:CalB' does not exist i

and is not recognised as a supported dataset name.

but the file "d:\Swathc_Test.hdf" is really exist in my harddisk
